The model 8001B Range Extender extends the measurement range of the model 8000A Potentiometer to 1200 Volts. All voltages are calibrated directly against the 10 V reference on the 8000B. The 8001B includes ranges of 10, 30, 120, 300 and 1200 V.
The 8001B maintains excellent short term drift and is self calibrating using the 8000B Potentiometer and a stable 10 Volt reference. The 8000B and 8001B combination can be used to calibrate and verify the linearity of both calibrators and DMM’s up to 1200 V.
