ACV: 600Vrms
ACA: F 11A /
1000V fuse
* Frequency measurement function is designed for ACV and ACA positions only.
* Auto range
* Accuracy range: ACV: 5 Hz~50 kHz
ACA: 45 Hz~5 kHz
* Pulse width: >0.01mS, zero-crossing waveform
* Input amplitude range:
ACV: 1.1V input amplitude≤600V. The frequency amplitude shall be <
greater than10% of range when performing HZ measurement at 60V and
600V ranges.
ACA: 600mA < input amplitude≤10A. The input amplitude shall be greater
than 3A when performing Hz measurement at 10A range.

* Range to ensure accuracy: 1%~100% of range
* The least significant digit at current range under open circuit is allowed to
be <2.
Note:
10~20 A: Perform measurement continuously for 10 seconds at most, then
stop for 15 minutes at least.
> 10 A: The display screen flashes, and the reading is for reference only.
> 20 A: OL is displayed.

* Display: True RMS of sinusoidal wave
* Range to ensure accuracy: 1%~100% of range
* The least significant digit is allowed to be <2 at current range under open
circuit.
* AC crest factor is up to 3 at 30000 counts, and is down to about 1.5 at 60000
counts. An additional error of ± 0.5 % is added for non-sinusoidal wave.
Note:
10~20 A: Perform measurement continuously for 10 seconds at most, then
stop for 15 minutes at least.
> 10.00 A: The display screen flashes, and the reading is for reference only.
> 20 A: OL is displayed.
