Measurement ranges
After switching the device on the distance selected distance is 2cm. If you want to measure with
that distance
6
you just have to place the device 2cm in front of the object to be measured. For
most cases this distance is ideal because charges up to 20kV can be measured (see specifica-
tions). But there are cases in which the measuring distance should be changed. In case of very
high charges or very rough surfaces the distance should be increased. In case of very low charges
the smallest distance (1cm) should be selected.
When the instrument switched off in the E-Field Meter Mode, it switches on in this Modus with
the last selected Range.
E-Field Meter Measurement
The unit can display the E-Field strength directly. By “change distance” (see downsize) select
the E-Field Meter Mode. In this Mode it’s possible to select the following ranges ± 20KV/m,
±200kV/m or ±1MV/m. To change the ranges press the «function/on» key briefly. The range
changed as following:
In this Mode there is no automatically change of the range. That’s why the DAC is now active.
Max. Value
The unit display in the “Max. Value” Mode in the upper row the maximum positive (right) and
negative (left) Value. The “Hold” Function is in this case out of order. By briefly pressing the
«function/on» key the maximum values will be erased and this function start again.
Analog Output
The instrument has a DAC – Output interface with ± 1V proportional to the measured electric
field strength. By exceeding more as 20% of the end range value “Over range” is displayed.
An Analog output is only useful in a manual range setting, that’s why it is only active in manual
E-Field Modus. In any other modes the DAC is deactivated and on the output always is “0V”.
