VCM100D/VCM80D Voltage check meters
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 Oil Test Sets are precision instrument that generates HV to 100 kV and needs to be transported and stored
carefully.
For PB models, a transportation case is available as an option and required by customers wanting to transport the
OTS80PB or OTS60PB by road, rail or air. A soft, shoulder carry case is provided as an option with the OTS80PB or
OTS60PB. It opens up to facilitate running a test without removal of the instrument and provides two side pouches for
storage.
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.
If the OTS80PB or OTS60PB has batteries fitted it should be fully charged at least once every three months to maintain
full battery capacity.
