[1] Specifications 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] Specifications are for 4–wire resistance measurement or 2–wire resistance measurement using REL operation. Without REL operation, add 0.2 Ω
additional errors in 2-wire resistance measurement.
[7] Accuracy specifications 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.

[1]
Typical value. Resolution is defined as the typical 20V range RMS noise (using auto zero “Once”).
[2]
Normal mode rejection ratio for power-line frequency ±0.1%. For power-line frequency ±1%, subtract 20dB. For ±3%, subtract 30dB.
[3]
Maximum rate for DCV, DCI, 2-wire resistance and 4-wire resistance functions.
