4. Measuring and testing
4.1 Testing voltage
Attention!
The function test (see 3.4) has to be performed successfully. Connect test electrode securely with the
test points. The following indication appears:
No operating voltage
Operating voltage
No voltage:
Interference voltage < Limit Ut:
Voltage > Limit Ut:
Attention!
With voltage of more than 36 kV AC / DC „OL“ without numerical value appears and an acoustic signal
accurs. In this case the test must be canceled immediately!
Ut = max. interference voltage. The value of Ut is labelled on the name plate.
Note:
Also on grounded systems interference voltages up to 300 V can be displayed.
Frequency indication
Simultaneously to voltage indication, the upper display line indicates the mains frequency in Hz.
With direct voltage „dc“ is indicated.
AC/DC Polarity
Type of voltage is indicated by symbole „~“ for AC and no sign or „–“ for DC. „-“ appears when minus
is applied with dirct voltage to the test electrode with display part. When plus is applied to the test
electrode with display part, no sign appears.
Application in moist environments
The DSP HS36 is approved for indoor and outdoor applications. In case of precipitation, the device has
to be wiped dry before usage. Workings in case of dense fog and impaired visibility are not approved.
