resistance drops below the Max Lmt setting or above the Min Lmt setting, or until the
RESET button is pressed to de-energize the output.
This operation emulates basic audible Continuity testers found on many multi-meters,
and is useful for doing multi-point Ground Bond tests on the DUT.
04 PLC Power Indicator
The PLC Power Indicator Option creates a signal that acts as an instrument power-on
indicator. The signal is available through the Remote Signal Output connector which
is located on the back of the instrument. This option closes the relay contact between
pin (1) and pin (2) on the output connector once the instrument is powered on. The
PLC Power Indicator signal replaces the PASS signal that is present on the standard
instrument.
It should be noted that the term "Indicator" in "PLC Power Indicator" only implies that
the instrument is powered on. To perform a test, it should be verified that an Interlock
device is used or the Interlock disable connector that was provided with the instrument
is installed, and that there are no failure indicators active on the instrument. For more
information on the Remote I/O and Remote Interlock refer to section 6. Connection of
Remote I/O.
05 External RS-232 Converter
The External RS-232 Converter option will allow for remote bus communication with
the HYAMP III. The following image should be used to mount the RS-232 converter
module to the case of the HYAMP III:
