SC77 Meter Reading Resistance Incorrectly
I have a Fieldpiece SC77 meter that I have been using for a couple of years. I noticed today that when set to measure resistance the meter shows between 0.5 and 0.8 ohms with the leads shorted together. I have tried some of my other leads and have the same issue. I mean I know 3/4 of an ohm is not a big thing, but I can put long leads on my meter, or little 5 inch ones and get the same reading.
Is this something I should be worried about? I am probably only worried because a month ago the k-type thermocouple mode was reading a few hundred degrees inside a 40 degree refrigerator. I tried 4 completely different thermocouples and a new battery and nothing changed. A couple of days later it is reading the proper temperatures again.
I guess I am a little skeptical of my meter now.
