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.
