Specifications are for 90-minute warm-up and 100 PLC integration time. When the integration time is <100 PLC, add the appropriate “RMS Noise
Adder” listed in the following table.
[2]
10% overrange on all ranges except DCV 1000 V and DCI 10 A ranges.
[3]
Relative to calibration standards.
[4]
For each additional volt over ± 500 V, add 0.03 mV 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 error 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 cause some
variation in the voltage drop across a diode junction.
