ARGUS Copper tests
The copper tests for ARGUS 300 and ARGUS 260 enable you to detect dangerous
voltages and currents early on and reliably assess the physical quality of the line –
particularly when DSL synchronisation is not possible or the data rate is low due to
asymmetry, interference sources or other mechanical line problems.
Technical features of the ARGUS copper tests at a glance:
Copper tests Multimeter
- Multiple, preconfigured measurement profiles can be executed as an auto test.
-Voltage measurement enables measurement of the supply voltage, as well as
external voltages caused e.g. by contact between two wires or isolation faults.
- With the aid of capacitive symmetry measurement, it is possible to detect asymmetry
in the subscriber line that can result in signal distortions or transmission errors.
-Capacitance measurement detects interruptions as well as typical input capacitances
of connected devices and enables estimation of line lengths.
-Isolation resistance measurement reveals damage to cable isolation, moisture
penetration or oxidised contact points.
- With the aid of resistance symmetry measurement, it is possible to detect irregula-
rities in the subscriber line that can result in signal distortions or transmission errors.
-Resistive fault location (RFL) can display resistance to fault (Rx), distance to fault,
resistance from fault to short circuit (Ry), loop resistance (Rs), line length, and fault
resistance (Rfault).
-Loop resistance measurement aids detection of short circuits and estimation of line
lengths.
-DC current measurement can be used to detect emergency, external and normal
power feeds as well as breaks in the line.
-Unbalance measurement (LCL): This measurement uses a frequency of 1 MHz to
measure asymmetry in a line pair.
-NEXT measurement: Measurement of near-end crosstalk at a frequency of 1 MHz.
-Signature detection is used to detect the signatures and test terminations (PPAs)
connected to the subscriber line.
- The fast cable check verifies the correctness of a three-pole (Tip/Ring/Ground)
connection.
- The integrated remote kit control lets you remotely set the line end to the desired
state either manually or automatically using a variety of electronic instrument kits.
Copper tests Oscilloscope
-Line Scope: High-performance realtime Line Scope with display in time and frequency
range (FFT) up to 35 MHz
-TDR: Time domain reflectometer to measure line lengths and locate faults

2 Safety information copper tests
There are the following safety specifications:
VDC 0 V to 200 V
VAC 0 V to 200 V
IDC 0 mA to 150 mA
ISO 105 VDC, max. 2 mA
R13 VDC, max. 15 mA
The following special instructions must be observed for the individual measurements:
Voltage
Be sure to observe the permissible measuring range specified above when measuring
voltage.
Capacitance/capacitive symmetry
Before measuring, make sure that the voltage thresholds given in the table below are not
exceeded during the measurement. Certain measurements can require a longer settling
time. An automatic “TRG-opt.” measurement can thus take some time.
Isolation resistance
Before measuring, make sure that the voltage thresholds given in the table below are not
exceeded during the measurement. During the measurement, the ARGUS can apply a
measuring voltage of up to 105 V max. 1 mA) to the line. Certain measurements can
require a longer settling time. An autotest can thus take some time.
Loop resistance/resistance symmetry
Before measuring, make sure that the voltage thresholds given in the table below are not
exceeded during the measurement. During the measurement, the ARGUS can apply a
measuring voltage of up ton 13 V (max. 15 mA) to the line.
DC current
Be sure to observe the permissible measuring range specified above when measuring DC
current. Make sure you connect the ARGUS in the circuit in series.

Longitudinal conversion loss (LCL)/NEXT
Before measuring, make sure that the voltage thresholds given in the table below are not
exceeded during the measurement. When measuring LCL or NEXT using the ARGUS,
any type of additional measurement lead can falsify the measurement. Both the length
and the position of the measurement leads with respect to each other can influence the
measurement result significantly.
Signature detection/fast cable check/remote kit control
Before measuring, make sure that the voltage thresholds given in the table below are not
exceeded during the measurement.
