400.0 V
600 V
Voltage
frequency
10 Hz~60 kHz
Caution:
• Short press "SELECT" in AC voltage/Hz scale to enter the Hz function;
• The input impedance is about 10 MΩ
• Current/voltage frequency response: 45 Hz ~ 400 Hz, displays true RMS
value
• Accuracy guarantee range: 1%~100%
• AC crest factor of non-sinusoidal wave can reach 3.0 at 4000 counts, while
it can only reach 1.8 at 6000 counts, the additional error should be added
for the corresponding crest factor as follows:
a. Add 3% when the peak factor is 1 ~ 2
b. Add 5% when the peak factor is 2 ~ 2.5
c. Add 7% when the peak factor is 2.5 ~ 3
3. Continuity/Diode measurement
