The top line of the display shows the selected measuring distance in cm, 
the bottom line shows the measured charge in Volts. If 999 V are reached 
during measurement, the unit automatically switches to the kV display 
range. The measured value is always displayed with three digits, 578 V; 
3,85 kV; 24,0 kV or 274 kV.
If the message "overflow!" appears on the display, select a larger measu-
ring distance!

Changing the measuring distance

Keep the "function/on" key pressed until the bottom line of the display 
shows "change distance" (approx. 2 sec). The topline shows the current 
distance in cm. You can now change the distance by briefly pressing the 
"function/on". The setting changes every time you press the key:
2 cm => 5 cm => 10 cm =>20 cm => 1 cm => 2 cm and so on. 
As soon as the desired setting appears in the display, wait 

without

 pres-

sing the "function/on" key until the bottom line again shows the current 
measuring value. The top line now shows the newly selected distance. 
This measuring distance is now used for any subsequent measurement.
The measuring distance results from the distance between the measuring 
electrode (behind the modulator wheel) and the measured object. The 
measuring electrode is located 3 mm ahead of the front of the unit. For 
this reason 3 mm must be added to every distance value when taking 
measurements from the front (aluminium plate).

Caution!

After switching the unit off and back on, the unit always returns to the 2 cm 
measuring distance setting!

HOLD

The instrument is equipped with a Hold function to "freeze" the measured 
value. The value measured at this point in time is held in the display by 
briefly pressing the "function/on" key once. The top line will show "Hold", 
the bottom line will show the measured value. The Hold function is swit-
ched off by again pressing "function/on" key briefly. The current measured 
value appears.
