The 15045 series is designed to calibrate the electrometers.
To dampprof the ultra-high resistor inside completely, the 15045 adopts a sealded case that passes a temperature cycle test and a load test.
The 15045 can be used as standard or calibrator of insulation resistance meters, and also as micro current meter in combination with a voltage source.
