Operation
Operation with Strain Gage Amplifier
The power switch on the PS-AC-0.8 unit activates the
AC Remote Amplifier Control Unit
and
illuminates the LED.
The bridge excitation switch, when used with the modular strain gage spinning amplifier, turns the
excitation to the bridge on or off without turning off the amplifier. This is done by inverting the
polarity of the + 15 V supply pins.
The shunt calibration switch remotely applies a positive or negative shunt resistance across bridge
terminals when used with a strain gage amplifier.
The LED is illuminated whenever the power is turned on.
Operation with Thermocouple Amplifier
The power switch on the PS-AC-0.8 unit activates the
AC Remote Amplifier Control Unit
and
illuminates the LED.
The bridge excitation and shunt calibration switches do not effect the operation of the thermocouple
amplifier.
The LED is illuminated whenever the power is turned on.
