• Display: True RMS
Accuracy guarantee: 5%~100% of range. Short circuit allows least significant digit ≤5.
•
Input impedance: ≥10 MΩ
•
• Frequency response: 40 Hz~400 Hz
• The AC crest factor will reach 3.0 at 3000 counts, while only ≤1.5 at 6000 counts. The additional
error should be added according to the crest factor of a non-sinusoidal wave:
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 0.1 Hz and accuracy is ±(0.1%+3). The input
amplitude should be ≥10% of range.
5. LPF ACV
Range

1000 V
Display: True RMS
Accuracy guarantee: 5%~100% of range. Short circuit allows least significant digit ≤5.
•
• Input impedance: ≥10 MΩ
• Frequency response: 40 Hz~200 Hz
The AC crest factor will reach 3.0 at 3000 counts, while only ≤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 -3 dB frequency of LPF is about 2.5 kHz
Only manual range for LPF ACV. Use the RANGE button to change the range.
• For voltage frequency monitoring, the resolution is 0.1 Hz and accuracy is ±(0.1%+3). The input
amplitude should be ≥10% of range.
6. LoZ V~
Range
600.0 V
1000 V
• Display: True RMS
Accuracy guarantee: 5%~100% of range. Short circuit allows least significant digit ≤5.
•
• Input impedance: About 2 kΩ
• Frequency response: 40 Hz~400 Hz
The AC crest factor will reach 3.0 at 3000 counts, while only ≤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 220 V, the continuous measurement time cannot exceed 30 s
and the rest interval should be more than 30 s.
• For voltage frequency monitoring, the resolution is 0.1 Hz and accuracy is ±(0.1%+3). The input
amplitude should be ≥10% of range.
