1.15. Hazardous Voltage Indication
The ES218 could provide the AC/DC hazardous voltage indication for voltage/resistor/ diode
modes. Of course, the indication could support LCD symbol /LED /Buzzer driving simultaneously.
Especially ES218 could detect the AC voltage in DCV mode and detects the DC voltage in ACV
mode. It means if not proper AC or DC voltage signal exists on the DUT when DCV or ACV
measurement mode is set, the HV indication will be still active.
HV indication criterion
Function / Range
DC voltage (typ.)

AC mV
> +3V
OL
AC 4V
> +20V
OL
AC 40V – 1000V
> +100V
> 30Vrms
DC mV
OL
> 3Vrms (40-1kHz)
DC 4V
OL
> 20Vrms (40-1kHz)
DC 40V-1000V
> +30V
> 90Vrms (40-1kHz)
Freq. mode
> +40V
> 30Vrms (40-1kHz)
Res/Diode modes
> +10V
> 10Vrms (40-1kHz)
Note: If AC+DC signal is applied, the voltage criterion will be changed.
