Accuracy guarantee: 5%~100% of range. Short circuit allows least significant
digit ≤5.
Input impedance: ≥10MΩ
Frequency response: 40Hz~400Hz
The AC crest factor will reach 3.0 at 3000 counts while only reach ≤1.5 at
6000 counts. The additional error should be added according to the crest
factor of a non-sinusoidal wave are:
a) Add 4% when crest factor is 1~2
b) Add 5% when crest factor is 2~2.5
c) Add 7% when crest factor is 2.5~3
For voltage frequency monitoring, the resolution is 0.1Hz and accuracy is
± (0.1%+3). The input amplitude should be ≥10% of range.

The AC crest factor will reach 3.0 at 3000 counts while only reach ≤1.5 at 6000
counts. The additional error should be added according to the crest factor of
a non-sinusoidal wave as follows:
a) Add 4% when crest factor is 1~2
b) Add 5% when crest factor is 2~2.5
c) Add 7% when crest factor is 2.5~3
The -3dB frequency of LPF is about 2.5kHz
Only manual range for LPF ACV. Use the RANGE button to change the range.
For voltage frequency monitoring, the resolution is 0.1Hz and accuracy is
± (0.1%+3). The input amplitude should be ≥10% of range.

The AC crest factor will reach 3.0 at 3000 counts while only reach ≤1.5 at
6000 counts. The additional error should be added according to the crest
factor of a non-sinusoidal wave as follows:
a) Add 4% when crest factor is 1~2
b) Add 5% when crest factor is 2~2.5
c) Add 7% when crest factor is 2.5~3
When the measured voltage is above 220V, the continuous measurement
time cannot exceed 30s and the rest interval should be more than 30s.
For voltage frequency monitoring, the resolution is 0.1Hz and accuracy is
± (0.1%+3). The input amplitude should be ≥10% of range.
