Check for H<>X Cable Reversal
The DTR 8510 may have detected a potentially hazardous step-up condition while attempting to test the transformer as con-
®
nected. 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 DTR
8510 charges in < 4 hours. The instrument can not be used to test when the batteries are charging.
