• Calibration
General
All instruments are fully calibrated before leaving the factory and
should not need adjustment until the next scheduled calibration.
However, if you change the voltage attenuator switches, you must
recalibrate the voltage input.
Equipment requirements
• Suitable accurate signal source for the inputs
(see calibration points table below)
• An accurate digital multimeter (accurate to 0.05 mV and
±0.1 μA)
• A suitable regulated power supply, AB 1606-XLP30E
• 931U-Cable connected to a PC with the Setup/Calibration
software.
Digital multimeters are frequently better at measuring voltages than
currents, so you may wish measure the voltage across an accurate
standard resistor (say 10 Ω ±0.05 %) when monitoring the output
current.
