Resistive Balance
Resistive Balance
At the start of the Resistive Balance test, the unit will check for the
presence of dangerous voltage and an active circuit. If dangerous voltage is
detected, a dialog box will be displayed to inform you and the test will stop.
If an active circuit is detected, a dialog box will be displayed to ask you
whether or not to proceed with the test.
Test Setup
The Test Setup tab allows you to
configure parameters for the resistive
balance test.
Each parameter is described below:
³
Res. Bal. Thr. (ohm) is the
resistive balance threshold ranging
from 0.1 to 20 ohm. If the
measured resistive balance in
ohms is greater than this threshold,
the fail icon is displayed. Otherwise, the pass icon is displayed.
³
Res. Bal. Thr. (%) is the resistive balance threshold ranging from 50 to
100 %. If the measured resistive balance in percentage is greater than
this threshold, the pass icon is displayed. Otherwise, the fail icon is
displayed.
³
Low Resistance Value defines which of the above thresholds will be
used to determine pass or fail. The range is 0.1 to 999.9 ohm. If the loop
resistance is less than the Low Resistance Value, the threshold in
Res. Bal. Thr. (ohm) will be used. Otherwise, the threshold in
Res. Bal. Thr. (%) is used.
