Resistance Meausurement; Continuity Test / Diode Test; Phase Rotation Determination; Rotary Field Indication - Unitest 2000 alpha Bedienungsanleitung

Carrying out Measurements
4.5 Restistance Measurement (only 2000 gamma)
Make sure that UUT is not live. Test voltage
polarity at handle test probe is positive (+).
" Check that UUT is not live by carrying out a double-
pole voltage test.
" Connect both test probes with UUT. Press Button
on rear side - for measurement point light (10) and
read value on the display.
The resistance range is 1...1999 Ω at a resolution
of 1 Ω.
If during the resistance measurement a voltage is
present the instrument switch automatically to vol-
tage measurement.

4.6 Continuity Test / Diode Test

Make sure that UUT is not live.
Test voltage polarity at handle test probe is positive (+).
" Check that UUT is not live by carrying out a double-
pole voltage test.
" Connect both test probes with UUT. A signal sound
is audible for continuity and the LED for continuity
Rx/Ω is illuminated.

4.7 Rotary Field Indication

The voltage testers are equipped with a double-pole ro-
tary field indicator.
The safety measures as mentioned in paragraph
2.0 have to be met.
The rotary phase indication is always active. The sym-
bols R " or #L are always displayed. However, the ro-
tary direction can only be determined within a three-
phase system. Here, the instrument indicates the
voltage between two external conductors.
" Connect the instrument test probe with the sup-
posed phase L2 and the handle test probe with the
supposed phase L1. Touch contact electrode (11).
The voltage and the rotary field direction are displayed.
