The model 8001B Range Extender extends the measurement range of the model 8000A Potentiometer to 1200 Volts. 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.
|Automated self-calibration.||Does not require sending out
|Bipolar voltage measurements.||Allows for automatic + and – voltage measurements against + 10 V reference.|
|Calibration of 57XXA.||Automated characterization of Fluke 5700A/5720A/5703A voltage output.|
|Calibration of DMM’s.||Can characterize the Voltage Linearity of Reference Multimeters like 3458A
|10 V to 1200 V DC range.||Enough range to calibrate all voltage calibrators without
|Low uncertainties.||1 × 10-6 for up to 1200 V.|
|Range||30 V, 120 V, 300 V, 1200 V|
* We have attempted to include all reasonable considerations for our uncertainty budgets but your uncertainty budgets should be re-assessed considering your environment, operating conditions and metrological needs. As this is a ratio device, the results that we show can easily be improved upon.
** Lower Voltages, e.g. 100 mV, 10 mV, 1 mV the resolution of the DMM (Detector) becomes the dominant uncertainty.
