Product description

Technical details :

"Limit Of Error” (or Worst Case) methods.
E Mode: ±(0.002% of setting + 0.0005% of range)
I Mode: ±(0.005% of setting + 1µA) compliance with variable control)
Accuracies based on one full year calibration cycle and conservatively specified by using the "Limit-Of-Error" (or worst case methods).
3 voltages ranges:
±100Vdc resolved to 100µV
±10Vdc resolved to 10µV
±100mVdc resolved to 0.1µV
2 current ranges:
±100mAdc resolved to 0.1µA
±10mAdc resolved to 0.01µA
Programming: Integrated microprocessor, GPIB interface. Local and remote control.
The control logic is microprocessor based.
True bipolar control with balanced zero.A “crowbar” zero reference may be selected.
Resolution 6 digits or 1 ppm

**Compliance Voltage Limit Control: The Compliance voltage may be limited via a manual control. The limits are ±100V, ±46V, ±32V, ±18V, ±4V, ±1V.

Accuracy: (See definitions under voltage mode) ±[0.005% of setting + 1µA].
Stability (*non-additive): 8 hrs, ±0.001%; 90 days, ±0.0015%;1 year, ±0.002%.
Line & Load Regulation (*non-additive): ±0.0005% for a 10% line fluctuation and from short-circuit to full compliance.

Applications:
Calibration of DVMs, DMM, meters, chart recorders, A/D converters, ATE, monitors, controllers, logging
systems, etc.
