NOTE: For Continuity, the instrument should be calibrated to a standard 5.0Ω
resistor rather than a 1.0Ω resistor. This change is reflected on the display
during calibration of continuity.
All other items in the Calibration Procedure remain unchanged. Please refer to the
section 9. Calibration Procedure for details.
04 PLC Power Indicator (all models)
The PLC Power Indicator option creates a signal that acts as an instrument power-on
indicator. The signal is available through the Remote I/O 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 signals/connections and Remote Interlock refer to
section 7. Connection of Remote I/O.
05 3 mA Output (3705, 3765, 3770 only)
The 3 mA Output option limits the AC output current of the instrument using software
control. The trip points are adjusted to a maximum of 3 mA and the software has
been modified so the high-speed maximum current shutdown is fixed at 3 mA. The
following specifications have been changed for this option:
