ACV-LPF
Warning:
● Do not input voltage over 2500V DC or 1500V AC. It is possible to measure higher voltage, but it may
cause damage to the Clamp Meter.
● For high voltage measurement, please pay special attention to avoid electric shock.
● If the measured voltage is ≥30V (AC/DC), the high-voltage warning symbol “ ” will be displayed.
“OL” will appear on the LCD if the measured voltage is >2510V DC and <-2510V DC or >1510V AC.
● If the DC voltage is less than -10V, the red backlight is lit up and the LED blinks for 10 seconds, the
buzzer sounds for 10 seconds, and the symbol “POLARITY” blinks.
● If frequency is displayed on the sub-display, then the input amplitude shall be ≥5V rms for
20Hz~100Hz and ≥10V rms for 100Hz~1000Hz.
● The low pass filter attenuates at -3dB and the cutoff frequency is 1.2 KHz.
