5.2.2 Loop Resistance Measurement (2-WIRE & GND)
Test Procedure
Select the RESISTANCE/2 WIRE & GND mode and press ENTER and
then the measuring arrangement appears:
The far ending of the tested pair should be joined manually or by means
of the remote controllable loop-closing device KLC 8.
Two measuring modes are provided: Sensitive or Protected mode.
It is recommended to start the measurement with sensitive mode. When
the interference voltages overload the indicator a warning appears
informing the user that the result can be inaccurate. In that case the
measurement should be repeated in protected mode.
• Select the proper mode with the MODE (F3) key
• Start the measurement with the START/STOP key
Having the measurement completed the test results appear.
Displayed Test Results
• Rl Loop resistance
• Ra, Rb Wire resistances
• RE Sheath resistance
To save the test result press the SAVE (F1) key
