All,
I just purchased a Vichy VC99. Though I have a Fluke 75 (which 30 years old and still going strong), the VC99 can measure temperature, capacitance, etc., things which the Fluke cannot do. Since I use a meter infrequently, spending big dollars did not make sense.
The meter arrived today as did a thermocouple probe. To test the meter, I made some ice water and put both thermocouples in it. Both indicated 36 F, not 32 F as expected. I then stuck my instant read food thermometer in the glass and it did read 32 F.
Question: Is there some way to field calibrate the meter? An error of 4F is horrifically bad and it is not clear if it is within spec. They claim +/-0.75%, but from what reference point? If they are referring to absolute zero, then this meter is right on the ragged edge of being within spec.
