Accuracy Specications: ± ( % of reading + % of range)
[1]
[1] Specications are for 90-minute warm-up and 100NPLC integration time. For integration
time <100NPLC, add the appropriate “RMS Noise Adder” listed in the following table.
[2] 10% overrange on all ranges except DCV 1000V and DCI 10A range.
[3] Relative to calibration standards.
[4] For each additional volt over ± 500 V, add 0.03mV error.
[5] For continuous current > 7A DC or 7A AC RMS, 30 seconds ON and 30 seconds OFF.
[6] Specications are for 4–wire resistance measurement or 2–wire resistance
measurement using REL operation. Without REL operation, add 0.2 Ω additional error
in 2-wire resistance measurement.
[7] Accuracy specications for the voltage measured at the input terminal only. 1 mA test
current is typical. Variation in the current source will create some variation in the
voltage drop across a diode junction.
