AT5600 User Manual 98-119 issue 14 Page 201
Status Error Codes
Test passed with no errors.
Voltage over-range occurred.
Current over-range occurred.
Ramp-up process has been aborted; too much load.
Error reported by the DC bias unit or that the DC bias unit did not respond to a
command.
The test signal could not be trimmed to required value; incorrect test parameters
for the load.
An error occurred after ramp-down; current did not decay away in time.
Current limit fail (Hi-pot tests only); test current exceeded pre-programmed limit.
The measured voltage did not go away in time; something on the fixture is staying
charged.
The test has been interrupted (see table below).
Where # = reason for the interrupt.
The safety interlock was broken during the test
Power more than limit requested. Power is above 25W. If this power level is
exceeded, we abort the test
A Hi-pot current trip has terminated the test; i.e. a flashover (spark) has occurred
or the current has exceeded the AT’s current capabilities (can occur on HPAC,
HPDC, ACRT, DCRT and IR).
A STOP input has terminated the test from the STOP input of the remote port or
the STOP button on the front panel
An 8KV overvoltage has been detected and terminated the test.
Class D overload. A hardware trip to protect the unit if >4A has been detected for
greater than a few microseconds.
An over-temperature interrupt has terminated the test; unit has become too hot.
An auxiliary fault interrupt has terminated the test; this can be created by an
accessory attached to the peripheral port.
Unit rebooted during the test sequence.
