Rotary Field Indication
* The voltage testers are equipped with a double-pole rotary
field indicator. Detection of the rotating field works only with
earthed systems. Both handles have to be held tightly in order
to ensure a capacitive coupling to the ground.
The rotary phase indication is always active. The symbols "R"
*
or "L" are always displayed. However, the rotary direction can
only be determined within a 3 - phase system. The instrument
indicates the voltage between two external conductors.
Connect the instrument test probe "L2" with the supposed
*
phase "L2" and the handle test probe "L1" with the supposed
phase "L1".
* The voltage and the rotary field direction are displayed on
LCD (P 1090) resp. LED (P 1095).
"R" signifies that the supposed phase L1 is the actual phase
*
L1 and the supposed phase L2 is the actual phase L2.
"L" signifies that the supposed phase L1 is the actual phase
*
L2 and the supposed phase L2 is the actual phase L1.
* When re-testing with exchanged test probes the opposite
symbol has to be illuminated.
Measurement Point Illumination
* Voltage testers are equipped with a measurement point
illumination feature.
* Thus, working under bad lighting conditions (e.g. division
switch cabinets) is made easier.
* Press button for measurement point illumination
instrument.
* A bright LED lights now the area before the probe "L2".
