Voltage Measurements; Phase Test - BEHA UNITEST ISO-compact Mode D'emploi

Prior to any usage, test the voltage tester for perfect
functioning by using a known voltage source.
Only touch test leads and test probes at handle surface
provided. Never dirctly touch test probes
Prior to switching to a different measurement range or a
new type of measurement, always separate connections
from EUT.
Safety Measures for Voltage Measurement
In order to avoid electrical shock, the valid safety and VDE
regulations regarding excessive contact voltages must receive
utmost attention, when working with voltages exceeding
120 V (60 V) DC or 50 V (25 V)rms AC. The values in
brackets are valid for limited ranges (as for example medicine
and agriculture).
Prior to using the voltage tester, ensure that test leads and
test instrument are in perfect condition. It is strictly prohibited
to use voltage testers if one or several functions are no
longer available or if the instrument function is no longer
obvious.
Only touch test leads and test probes at handle surface
provided. Never directly touch test probes.
Befor using a voltage detector with audible indicator at loca-
tions with a high background noise level it shall be determined
whether the audible signal is perceptible.
4.1 Voltage Measurement
The ISO-Compact may carry out DC and AC voltage measurements
as well as phase tests. The instrument switches on automatically
as from 20 V approx. DC or AC voltages and displays the value on
the LCD. For smaller voltages press the button "Voltage Test".
If the button "Voltage Test" (4) is pushed, all other measurements
like insulation test or battery test are interrupted.
' Press the button "Voltage Test" (4) and contact UUT.
' The measurement value and polarity (only for DC) are displayed.
For AC voltage the symbol AC is displayed. For DC voltage the
symbol DC is visible. A beep sound is audible and the symbol
")))" appears in the display.
' The polarity of teh instrument test probe is positive.

4.2 Phase Test

For single-pole tests the phase must be in contact at instrument
test probe. The instrument switches on as from a voltage of 70 V
and indicates the phase via a beep sound.
