MicOvac Test Meter

MicOvac Test Meter

The MicOvac test meter is basically a valve-voltmeter but is of robust design and suitable for the ordinary needs of test and servicing work.

It provides for DC and AC voltage measurement up to 500 volts in five ranges, and with the addition of an external multiplier the DC facilities are extended to 5,000 volts. As the internal resistance is 1 MΩ per volt on DC up to 150 volts, and 5 MΩ total above 150 volts, direct measurement of AGC bias voltages, screen potential and EHT in television sets is possible.

On AC the resistance is 10 MΩ total and the upper-frequency limit is to 10 Mc/s up to 150 volts and 10 kc/s on the higher ranges. But by using an external probe unit the limit can be raised to 200 Mc/s.

The instrument also provides for DC and AC current measurements from 0 -15 µA up to 0 -1.5 A full-scale reading in five ranges and resistance up to 100 MΩ in two ranges.

It is self-contained and battery-operated and is assembled in a functionally designed moulded case.

The price is £24 10s. The 5,000-volt DC multiplier costs 22s and the VHF probe unit 25s.
