Used to measure very high resistance such as insulation by measuring the small current that flows when a fairly high voltage is applied.
The instrument has three ranges:
1) Megohms with 500V applied
2) Ohms with 300 mV applied
3) Internal battery test
A transistorised inverter is powered by 6 AA cells.
