INSTALLATION
Refer to the installation drawing for details. If the
microsensors are to be subjected to pressures beyond
their specified range, be sure to use backing nuts to
prevent the sensors from backing out of their
mounting ports. (Thread adaptors are available from
PCB to facilitate mounting.)
Connect the microsensors to an ICP
power supply.
Use standard two-conductor cable between the sensor
and the ICP
power unit.
Next, connect the power unit to a readout device, e.g.,
oscilloscope, recorder or high-speed A to D
converter.

OPERATION
Switch the ICP
power unit on and observe reading of
bias-monitoring voltmeter on front panel of power
unit.
If indicator is in green section of indicator panel, the
IC amplifier is providing proper bias (normally +11
VDC), cable connections are normal and the system
is ready to operate.
If the needle moves to the red area of the fault
monitor meter, output is zero and a short is indicated.
The short could be located in the amplifier cable
connectors or in the power unit.
If the pointer moves into the yellow area of the fault
monitor meter, an open circuit is indicated with full
power supply voltage. An open circuit could be the
result of a faulty amplifier, an open cable or open
connectors.
Allow the sensor to thermally stabilize for about one
minute. A signal drift may occur when the output
cable is connected to the readout instrument.
The drift occurs during charging of the coupling
capacitor in the power unit. The signal will stabilize
in several minutes.
