Rated 1 out of 5 by from Defective EXTECH EX530 purchased a multimeter recently (order HQ02088673). I received the multimeter but it is defective out of the box. The voltmeter mV AC mode fluctuates up to 4 mv and never gives the same reading when I short the probes together. It never goes to (or near) zero. The best stable reading I got was 0.08 mV AC. It started to fluctuate again when I released and re-shorted the probes again. I bought the EXTECH EX530 for that specific mode. (resolution of 0.01 mV in AC). I don't mind a stable zero offset. But a drift of over 400 graduations is unacceptable. There is also a problem with the ohm meter. It fluctuates and I can not trust the continuity function (beeb) as it comes on and off whit the probes on a short peaces of steel. Even with pressure applied. I tried a different set of probes and it does the same thing. In the RMA process for repair

Does a new purchase of one of these units come NIST-traceable calibrated and with a certificate of calibration?

Asked by: Platinum Pal
This series of meters can be ordered with a optional NIST certificate and/or a Certificate of Calibration so send a request for pricing to sales@omega.com with the specific model of interest.
