craftsman 82357 multimeter manualDid you miss your activation email ? If so, would they be kind enough to open it up and tell me the measurement of the R41 resistor. Mine is burnt and I cannot properly read the colour values, but need to replace it. I really do not want to replace the DMM. I've tried looking for the same one for sale, but have had no luck. I really love this DMM. Thanks! Does anyone have a Craftsman 82357 Digital MultiMeter. If so, would they be kind enough to open it up and tell me the measurement of the R41 resistor.

In your other thread I put a link to a page with the PC software in a zip file. I have been to that page in my other post, a few times over the years, and was in touch with the owner of that site before posting my question for help here. With physical appearances, it's closest to the 20TRMS. Mine is a True RMS Autoranging PC Interface DMM. It's the pictures for the various functions that look different on mine. I see in the datasheet for the 20TRMS, the T means Temperature and the RMS means True RMS multimeter, so although it looks a little different with the printing on the case, mine would be the 20TRMS. I'll use that to see if I can find more out about it.http://casms.org/atts/news-files/e-cigarette-510-manual.xml

I could not find much info on the LP2 version of this chip. I've uploaded some pictures, maybe it would help. I believe the R41 and R40 might have something to do with current measurements, but I am not certain. Is there a chance this Craftsman one could have been available before the Wens one. For some reason, I remember it being purchased before 99. I graduated in 99, so I use that as a reference point, and for some reason, I remember having it for a couple years before graduation. I could be mistaken. I searched at Fortune Semi Corp. Maybe at one time the probes stuck in the wrong jacks?) This happens to the best of us. Did you enjoy that nice magic smoke? I searched at Fortune Semi Corp. Maybe at one time the probes stuck in the wrong jacks?) This happens to the best of us. Did you enjoy that nice magic smoke. My memory is a bit faulty, so it must have been purchased in 1999. I believe I know what happened. It happened months ago. I was careless and hired some help to help repair some TVs. The person who was helping claimed they had a lot of expierence and knew exactly what they where doing. They were working on the backlighting for a Samsung TV I believe and I heard this bang. If memory serves, they crossed the probes while trying to measure one of the input filter caps. They grounded it out and it ended up burning a small dip in my actual probes. I don't know why they where even messing around with the PSU. I had already told them what was wrong and what needed to be done and they said they had understood. It didn't damage the TV anymore than it was already damaged, and thankfully, the guy wasn't hurt (except for maybe his ego a little?). I think that's probably what damaged the DMM. After that, it started acting up. More than one decimal point on the screen, locking up while trying to take measurements. Currently, I have to assume that any measurements taken with it could be completely useless.http://aradovan.com/userfiles/e-auction-manual.xml That one company said no parts, no service manual, but they have a Wens 20TRMS they'd sell me, new, for 125 USD FOB (what ever FOB means). I took those pictures a few weeks ago, when I asked for help on BadCaps (but didn't have much luck). So I came here and shrunk them and then uploaded them. I can tear it apart and pull R40 and R41. If R40 measures 990 ohm, and I trace to see if it follows that circuit, I think we found the value of my burnt out resistor. These are tolerant resistors, 1 I believe. I wonder if more accurate ones would make the meter more accurate for current measurements? The burned out resistor. I have other ways to measure currently.but being burned out, I read it as open when I tried measuring in circuit. I figured if it measures open in circuit, it'll for sure measure open if I pulled it, and I didn't go any further there. Thanks. I need a good bench DMM, but I still need my portable jobby for certain tasks. I'll keep that link bookmarked for when that time comes. I believe Agilent bought HP, and then Keysight bought Agilent, or something like that, so in the end, Keysight ended up with all of the equipment. I would end up either buying something with a traceable calibration, or send it out to get calibrated. I've been in need of a benchtop DMM for a long time, but everytime I remember, I'm in a bad financial place. When I'm in a good financial place, I don't remember!!!!!

This was not the result of increased Myc protein levels, as Myc levels were lower with coexpression of Pin1 ( Fig. 1A, blots), consistent with Pin1 facilitating Myc turnover ( 18 ). S1A in the supplemental material), suggesting that Pin1 may regulate Myc chromatin association, which could help explain its effects on Myc transcriptional activity. S1B in the supplemental material). Thus, Pin1 increases Myc-driven transcription and enhances Myc DNA binding even with reduced Myc protein levels. One percent of the input was used for Western blotting. P values are shown for relevant significant comparisons. An asterisk indicates a P value of less than 0.001. The error bars indicate standard errors. Manipulation of Pin1 levels had no effect on Myc binding to p15 and p21 promoters ( Fig. 1D ). Moreover, expression of these endogenous target genes correlated with Pin1-mediated changes in Myc DNA binding, where Pin1 overexpression increased expression of all four trans -activated targets and had no effect on the expression of p21 and p15 ( Fig. 1E ). The opposite results were seen after knockdown of Pin1, where Pin1 depletion decreased expression of the trans -activated targets without affecting p21 or p15 ( Fig. 1E ). To test the Myc dependency of the Pin1 effects on endogenous Myc target gene expression, we overexpressed Pin1 with or without Myc knockdown. While Pin1 overexpression increased the expression of nucleolin and E2F2, knockdown of Myc suppressed expression of these genes regardless of Pin1 overexpression ( Fig. 1F ). We performed similar experiments in human mammary epithelial MCF10A cells, where, similar to the HEK293 results, we observed that Pin1 overexpression increased the association of endogenous Myc with the four trans -activated promoters but had no effect on binding to the trans -repressed p21 promoter (see Fig. S1C in the supplemental material), while Pin1 inhibition with PiB, a small-molecule inhibitor of Pin1 ( 39 ), had the opposite effect, decreasing Myc binding to the trans -activated promoters without affecting binding to p21 (see Fig. S1C in the supplemental material). In addition, changes in Myc promoter binding correlated with changes in the expression of the endogenous Myc target genes in MCF10A cells (see Fig. S1D in the supplemental material). We also observed that Pin1 enhances Myc promoter binding at E-box sites (see Fig. S1E in the supplemental material), which could explain the lack of an effect of Pin1 on Myc binding to p15 and p21 promoters, since these are trans -repressed through other promoter elements ( 40, 41 ). Thus, Pin1 positively regulates Myc promoter binding at all trans -activated target genes tested, and this correlates with changes in their expression. Pin1 regulation of Myc activity requires functional phospho-binding and isomerase domains in Pin1 and serine 62 phosphorylation of Myc. To determine which domains of Pin1 are important for its ability to regulate Myc promoter binding and transcriptional activity, we expressed a Pin1 WW domain mutant, which contains a point mutation in the WW domain (W33A) that inhibits its interaction with phosphorylated substrates ( 42 ), and a catalytically inactive Pin1 mutant, Pin1 CM, which contains a point mutation in the isomerase domain (C109A) ( 43 ), in HEK293 cells and performed luciferase assays with the 4xEbox-Luc reporter to measure affects on Myc-driven transcriptional activity. We found that the Pin1 WW and Pin1 CM mutants were unable to stimulate the transcriptional activity of Myc like Pin1 WT ( Fig. 2A ). In addition, neither mutant was able to regulate Myc DNA binding ( Fig. 2B ), demonstrating that Pin1's phospho-substrate binding domain and isomerase activity are required for its stimulation of Myc's transcriptional activity and DNA binding activity. Open in a separate window Fig 2 Pin1 regulation of Myc activity requires functional phospho-binding and isomerase domains in Pin1 and serine 62 phosphorylation of Myc. (A) Luciferase assays were performed after expression of the indicated plasmids in 293 cells, as in Fig. 1A. (B) 293 cells were transfected with empty vector or the indicated Pin1 expression plasmids (V5-Pin1 WT, V5-Pin1 CM, or V5-Pin1 WW ).Statistical significance is indicated as in Fig. 1. The error bars indicate standard errors. Since Pin1 is reported to be a phosphorylation-directed prolyl isomerase and the WW phospho-binding domain is required for its regulation of Myc, we tested the role of Myc phosphorylation at T58 and S62 in Myc's response to Pin1. We performed luciferase assays with the Myc T58A and S62A phosphorylation mutants and found that Pin1 had reduced effects on the activity of Myc T58A to drive E-box-mediated transcription and no effect on the activity of Myc S62A ( Fig. 2C ). We also examined the ability of Pin1 to regulate Myc S62A or Myc T58A binding to chromatin using stable Dox-inducible MCF10A-Myc WT, MCF10A-Myc T58A, and MCF10A-Myc S62A clones. Pin1 again enhanced Myc WT binding to the E2F2 gene promoter, with reduced Myc protein expression ( Fig. 2D, graph and blot, lane 2). However, Pin1 had a reduced effect on the binding of Myc T58A and no effect on the binding of Myc S62A, while also not affecting the expression of either mutant, consistent with our previous results showing that Pin1 does not regulate the degradation of these mutants ( 18 ). Furthermore, while Pin1 enhanced E2F2 mRNA expression driven by Myc WT in these cells, it only moderately enhanced activation of E2F2 mRNA expression mediated by Myc T58A and it had no effect on Myc S62A activation of E2F2 ( Fig. 2E ). Thus, Pin1 activation of Myc involves S62 phosphorylation of Myc, Pin1's phospho-substrate binding domain, and its catalytic activity, suggesting that Pin1 interacts with and isomerizes pS62-Myc to enhance its DNA binding and transcriptional activities. Pin1 associates with pS62-Myc at Myc-responsive promoters. To test whether Pin1's regulation of Myc occurs at Myc target gene promoters, we assayed for the presence of Pin1 at Myc-regulated promoters. We detected V5-Pin1 WT by qChIP at each of the Myc trans -activated target promoters, but not p15, using the same primers as for Myc qChIP, which span the Myc binding site(s) ( Fig. 3A ). In contrast, V5-Pin1 WW was unable to associate with these promoters ( Fig. 3A ). We also detected endogenous Pin1 at the same Myc target promoters, and this binding could be reduced with Pin1 knockdown (see Fig. S2A in the supplemental material). In addition, the association of Pin1 with Myc target genes was enhanced by increased Myc expression ( Fig. 3B ). To verify that Pin1 is recruited to Myc-responsive promoters via Myc, we measured endogenous Pin1 binding to the E2F2 and nucleolin promoters after Myc knockdown in 293 cells. As shown in Fig. 3C, knockdown of Myc reduced Pin1 binding to these promoters. To test whether Myc and Pin1 can cooccupy Myc-responsive promoters, we performed sequential qChIP experiments. Ectopic Myc and Pin1 associated with the nucleolin and E2F2 promoters ( Fig. 3D ). Following release of the bound material from the Myc immunoprecipitation, we were able to sequentially qChIP Pin1 at these promoters ( Fig. 3D ). Similar results were found with endogenous Myc and Pin1, except the p21 promoter was also tested, and Myc, but not Pin1, was detected here (see Fig. S2B in the supplemental material).
