For DC functions, accuracy is the specified accuracy of the measurement function ± 12 counts for changes longer than
275 ms in duration.
For AC functions, accuracy is the specified accuracy of the measurement function ± 40 counts for changes longer than
1.2 s in duration.
1. All AC voltage and AC current ranges are specified from 5 % of range to 100 % of range.
2. Frequency is specified from 2 Hz to 99.99 kHz in Volts and from 2 Hz to 30 kHz in Amps.
3. For serial number 83911000 and below, frequencies < 10 kHz are not specified in 600 mV ac, 60 mA ac, and 6 A ac ranges. For Serial
numbers between 83911001 – 83911240 and 84060001 and above, this note does not apply.
4. Below 2 Hz, the display shows zero Hz.
5. Noise at frequencies below 4.5 Hz and amplitude below 600 mV may exceed the frequency specification.
6. Amps input burden voltage (typical): 400 mA input 2 mV/A, 10 A input 37 mV/A.
7. Does not include error of the thermocouple probe.
