For dc functions, accuracy is the specified accuracy of the measurement function ±12 counts for changes longer than 350 ms in

duration.

For ac functions, accuracy is the specified accuracy of the measurement function ±40 counts for changes longer than 900 ms in

duration.

[1] All ac voltage and ac current ranges are specified from 5 % of range to 100 % of range.

[2] Crest factor of ≤3 at full scale up to 500 V, decreasing linearly to crest factor ≤1.5 at 1000 V.

[3] For non-sinusoidal waveforms, add -(2 % reading + 2 % full scale) typical, for crest factors up to 3.

[4] In the 9999 μF range for measurements to 1000 μF, the measurement accuracy is 1.2 % + 2 for all models.

[5] Amps input burden voltage (typical): 400 mA input 2 mV/mA, 10 A input 37 mV/A.

[6] 400.0 mA accuracy specified up to 600 mA overload.

[7] >10 A unspecified.

[8] Frequency is specified from 2 Hz to 99.99 kHz in Volts and from 2 Hz to 30 kHz in Amps.

[9] Below 2 Hz, the display shows zero Hz.

[10] In RF field of 3 V/m specified accuracy ±5 °C (9 °F).

[11] Does not include error of the thermocouple probe.
