LoZ ACV 600.0 V
LPF ACV 600.0 V
• Input impedance: approx. 10 MΩ.
• True RMS display.
• Frequency response: 40 - 400 Hz. LPF frequency response: 40 - 200 Hz.
• After using the LoZ function, please cool down the meter for 1 minute.
• Accuracy guarantee range: 5~100% of range, short circuit allows least significant digit
<5.
• The AC crest factor is ≤2.5 when measured at 4000 counts. The full range AC crest factor
of 6000 counts is ≤1.8.
• Non-sinusoidal waveforms:
- When the crest factor is 1.0 to 2.0, the accuracy must be increased by 4.0 %.
- When the crest factor is 2.0 to 2.5, the accuracy must be increased by 5.0 %.
- When the crest factor is 2.5 to 3.0, the accuracy must be increased by 7.0 %.
• Input voltage: max. 600 Vrms.
