DMM SPECIFICATION FOR SEMI-AUTOMATIC USE
The Voltech calibration system relies on the accuracy of the DMM used to achieve the
published specification of the tester. The meter must measure:
AC Volts to 0.04% @100Hz and 3% @1MHz
DC Volts to 0.003% @2V and 0.005% @600V
DC resistance using a four terminal connection to 0.05% for 500mΩ and 0.01% for
750Ω.
Keithly 2002 and Datron Wavetek 1271 (with high accuracy AC option) DMMs are
suitable alternative meters.
CALIBRATION ENVIRONMENT
Calibration should be carried out at 23°C ±5°C, relative humidity 10 to 90% non-
condensing.
