Accuracy Specifications ± (% of reading + % of range)
1
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
mVrms. 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
Vrms add 0.7 mVrms 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 1 A and 3 A ranges.
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.
