Display
The display is a double-spaced alphanumeric LCD display with 12 digits in each row (2 x 12). In
the upper line the selected distance is displayed in cm. In the bottom line the measured charge is
displayed in Volt. Over 999V on the display changes to kV display.
The displayed value is always triple-digit:
Examples:
If the measure field strength is too high „overflow! “ is displayed, the distance has to be
increased.
Battery Monitoring
The device has permanent battery voltage monitoring. By undercutting a battery voltage of 7.6V
the upper line displays: „Low Battery!“. In that case the 9V battery has to be charged or renewed.
By undercutting 7.1V the display shows “auto off” for about 2s and the device powers off to pre-
vent further damage.
Attention:
Use only Rechargeable 9V – NiMH Battery or an 9V Alkaline Battery
Batteries have to be charged outside the device in a suited battery charger. Please pay attention
to the manufacturer instructions! Used batteries can be returned to us or have to be disposed
professionally.
Grounding
The device has to be grounded properly to measure the amount and the polarity of an electro-
static field. For that purpose the device has to be connected to ground by using the grounding
jack (4). Grounding the device by a grounded person (e.g. over conductive shoes or wrist strap)
touching the grounding jack suffices under most circumstances.
Maintenance
The modulator system or parts of it must not be touched. Those parts have to be protected of
dust, isolating impurity layers, color- or paint haze and condensate.
If required the modulator system can be cleaned with ethyl alcohol and a lint-free cotton cloth.
