VCM100D/VCM80D Voltage Check Meter
The VCM100D and VCM80D are OTS accessories that enable the voltage output of the oil test set to be checked by
measuring the actual voltage at the HV electrodes. The calibration meters fit in the oil test set chamber in place of a
standard vessel and are designed to ensure that the load on the OTS transformer is similar to the load during an oil
dielectric strength test.

Storage and transportation
The OTS100AF/80AF/60AF are a precision instruments that generates high voltage to 100 kV and needs to be transported
and stored carefully.
The unit should be stored in a room or area where the environment is within the temperature range of -30 ºC to 65 ºC
and maximum humidity of 95% at 45 ºC.
