Notes:

[1] All AC ranges except Auto-V LoZ are specified from 1 % to 100% of range. Auto-V LoZ is specified from 0 V.

Because inputs below 1 % of range are not specified, it is normal for this and other true-rms meters to display non-

zero readings when the test leads are disconnected from a circuit or are shorted together. For volts and μA, crest

factor of ≤3 at 4000 counts, decreasing linearly to 1.5 at full scale. AC volts is ac-coupled. Auto-V LoZ, AC mV, and

AC μA are dc-coupled.

[2] Temperature uncertainty (accuracy) does not include the error of the thermocouple probe.

[3] Frequency is ac coupled and specified from 5 Hz to 50 kHz.
