1
Specifications are for 90 minute warm-up and 100 PLC.
2
Relative to calibration standards.
3
20% overrange on all ranges, except DCV 1000 V, ACV 750 V, DCI and ACI 3 A ranges.
4
For each additional volt over ± 500 V add 0.02 mV of error.
5
Specifications are for sinewave input > 0.3% of range and > 1 mV
rms
. Add 30 µV error for frequencies below 1 kHz.
750 VAC range limited to 8 x 10
7
Volts-Hz. For each additional volt over 300 V
rms
add 0.7 mV
rms
of error.
6
Specifications are for 4-wire resistance measurements, or 2-wire using Math Null.
Without Math Null, add 0.2
Ω
additional error in 2-wire resistance measurements.
7
Specifications are for sinewave input > 1% of range and > 10 µArms. Frequencies > 5 kHz are typical
for all ranges. For the 3 A range (all frequencies) add 0.05% of reading + 0.02% of range to listed specifications.
8
Specifications are for 1-hour warm-up using Math Null. Additional errors may occur for non-film capacitors.
9
For total measurement accuracy, add temperature probe error.
10
Accuracy specifications are for the voltage measured at the input terminals only. 1 mA test current is typical.
Variation in the current source will create some variation in the voltage drop across a diode junction.
