2 Safety information
ARGUS Copper Box
9
Important instructions for use:
1.
Even a measurement on low-power telecommunications networks can present hazards
- particularly in the event of a fault; consequently, always first check the line to be tested
for a supply (DC voltage) and an external voltage (DC or AC voltage). If even one of
these conditions is present, safely de-energise this voltage and secure it against being
switched on again before conducting any further tests.
2.
Once ARGUS detects the ARGUS Copper Box, an auto test can be executed or each
separate measurement can be started and stopped individually. If you change the
measurement without first stopping, the measurement is stopped automatically.
All voltages >200V are outside the permissible limits.
3.
Never switch the ARGUS Copper Box from line to line while a measurement is running.
This would bypass the safety voltage measurement conducted before the start of each
measurement. Connecting the Box with a running resistance measurement to a line
with a regular supply voltage, for example, could destroy the Box even if this voltage is
within the specification for voltage measurement. In general, the ARGUS Copper Box
automatically checks before every measurement (except current measurement)
whether the line is carrying a voltage, and stops the measurement with a message as
necessary.
4.
The ARGUS Copper Box is equipped with an automatic “TRG-opt.” measurement. This
means that the measurement quantities can be measured between different wires,
such as a (Tip), b (Ring), Ground and optional socket (opt.). The ARGUS tester
displays for selection the pairings that the ARGUS Copper Box supports for the various
measurements. Except for measurement of isolation resistance, the ARGUS Copper
Box performs a continuous measurement when only one wire pair (e.g. Tip/Ring or Tip/
Ground or Ring/Ground) is selected, i.e. changing values appear immediately on the
display.
