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.
