Arc-Fail: This message appears on the display if the DUT arcing current exceeds the
Arc Sense limit and Arc function is active (Arc Sense = 1…9) during the AC/DC
Withstand test.
Short: This message appears on the display if the instrument detects a short circuit
condition
Breakdown: This message appears on the display if the DUT current is well beyond
the metering range of the test and the arcing condition is beyond the arc sense limit.
GND-Fault: This message appears on the display if the GFI threshold is exceeded
during the test.
Interlock Open: This message appears on the display if the Remote Interlock feature
is activated before or during a test. See section 6.2. Remote Signal Inputs and
Memory Access for more information.
Out-Error: This message appears on the display if the instrument has an internal
problem and the TEST button is pressed. The RESET button is not active while this
screen is displayed. To clear this screen and return to test mode press the “Exit” soft
key. When the “Exit” soft key is pressed the instrument will continue with its normal
failure indication process. The failure light and Alarm can then be cleared by pressing
the RESET button.
NOTE: If the instrument continues to power up in this condition it should be
sent in for service or repair.
WARNING: Voltage detected at return : This message appears on the display if
external voltage or current is detected on the front or rear RETURN terminals on the
instrument. The 3700 series instruments have a resettable fuse installed on the return
in the event external line voltage is applied to the return terminals. This circuit will cut
the return off from the internal components in order to avoid damage to the
instrument. If this message is shown on the display, check all connections and remove
the fault. Note that there is a 5 second wait time on this error message. The fuse must
reset before a test can be run again.
