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".
Voltage measurement with low internal impedance (P 1090)
This function is particularly useful for testing installations. Due to
the lowered internal impedance.
Capacitive voltage is suppressed. The reading shows the actual
voltage applied. Similarly, measuring phase "L1" on earth wire
"PE" may trigger fault-current circuit breakers (FI or RCI). This
measuring procedure can be used for measurements above 12V.
Always hold the voltage tester by the handles designed for this
purpose. Never touch the device beyond the handle ends.
Hold the two test tips onto the measuring points to be tested.
Press the two push-buttons and simultaneously. The applied
voltage is shown on the LCD display. The Low-Imp LED signals
low impedance measurement.
