and Response Time
1. All AC voltage ranges are specified from 5% of range to 100% of range. Because inputs below 5% 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.
2. Crest factor of 3 at full scale up to 300 V, decreasing linearly to crest factor
3. For non-sinusoidal waveforms, add -(2% reading + 2% full scale) typical, for crest factors up to 3.
4. The 6000 mV range can only be entered in Manual Range mode.
5. For film capacitors.
6. Crest factor of 3. AC current is not specified below 3A. 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.
7. Hz is specified from 5 Hz to 50 kHz in volts, from 50 Hz to 5 kHz in amps.
8. Amps input burden voltage (typical): 400 mA input 2 mV/mA, 10 A input 37 mV/A

Accuracy is the specified accuracy of the measurement function
( 40 digits in AC). Typical response time: 100 ms to 80 % of signal, except V AC and A AC.
