Comp; Ac/Dc Voltage Measurement - BEHA Unitest TELARIS ISO Bedienungsanleitung

6.2.1 COMP

The instrument TELARIS ISO is able to compen-
sate test lead resistance. Proceed as follows:
Connect black test lead to „COM" socket and
blue test lead to „Ω" socket.
Short-circuit both connected test leads.
Press „COMP" key.
If the test lead resistance has been com-
pensated correctly, the display indicates
the symbol „COMP" (5) and the value 0.00
Ω. Furthermore, the acoustic signal is
audible (also refer to chapter 7.0).
To exit compensation mode, press „COMP"
key again.
6.3 AC / DC Voltage Measurement
In order to obtain precise measurement
results, you should switch off all loads or
disconnect them from mains.
COMP / AC-DC Voltage Measurement
Connect red test lead to „U
black test lead to „COM" socket.

of measurement range selection switch (14).
Select AC or DC voltage by pressing key
„AC/DC" (13).
When switching on or changing the
„UAC/DC" measurement range, the „AC"
range is automatically selected.
Now connect test leads to UUT:
Read measurement result on display.
voltage protection for voltage measurement
When applying an external voltage of
max. 600V AC/DC to voltage sockets, the
instrument TELARIS ISO will not be
damaged for a duration of 10 seconds.
The instrument displays „>550V" (also
refer to chapter 7.0). After removal of
external voltage source, wait approxima-
tely 30 seconds to obtain correct measu-
rement results.
