7.1. Display messages
Check for H<>X Cable Reversal
The TR8703 may have detected a potentially hazardous step-up condition
while attempting to test the transformer as connected. Verify connections.
High Excitation Current
Check test cable connections for inadvertent short circuits. Check for
shorted transformer windings.
Low Battery
As the batteries are drained during use, the green LED will begin to flash
when the battery voltage reaches a pre-determined threshold. The tests
can be run as usual during this time but the batteries will soon need to be
charged.
As the batteries reach a predetermined threshold, LOW BATTERY
indication will appear on the display. All the buttons will be non-
operational now. The batteries must be recharged in order to continue
testing.
NOTE: The TR8703 charges in <4 hours. The instrument can not
be used to test when the batteries are charging.
X Circuit CONT or OPEN
The ------ indication is for CONT (Closed switch). It indicates a good
connection.
The --/-- indication is for OPEN (Open switch). It indicates a poor or open
connection.
The message "Check X Connection" will be displayed.
