VEVOR EM4659 Bedienungsanleitung Seite 16

Frequency Range:
40Hz - 400Hz ( only for 6V range )
40Hz - 1kHz ( only for 60V, 600V and 750V ranges )
Note:
Except for sine wave signal and triangular wave signal
measurements, accuracy specifications for ac voltage
measurements do not apply to measurements of signals whose
frequencies are > 200Hz.
Reading: True rms
Max. Allowable Input Voltage: 750V ac
Note:
1. 750V range is specified from 20% of range to 100% of range.
2. When the input terminals are open, the display may show a reading
other than zero. This is normal and will not affect measurements.
[1] If the voltage being measured is≥750V, the built-in buzzer will sound.
If the voltage is > 760V, the display will show " OL ".

Note:
1. 60A and 600A ranges are specified from 10% of range to 100% of range.
1000A range is specified from 20% of range to 100% of range.
2. In 1000A range, if the current being measured is≥1000A, the built-in
buzzer will sound, and if the current is > 1010A, the display will show "
OL ".
