Operating Procedure
OPERATION FROM AC POWER MAINS
Plug the line cord into the appropriate AC power source and move the power switch toggle to
the ‘AC POWER’ position. The indicator lights on the front panel will glow and the voltmeter will
indicate full scale with no sensors attached to the sensor jacks.
If these indications are not present, check the fuse at the rear panel. If it is blown, replace it
with a 1/4 Amp 3AG fuse only.
OPERATING THE POWER UNIT
Connect the sensor to any one of the ‘Sensor’ jacks at the rear panel of the power unit. Rotate
the channel selector switch on the front panel to the number of the channel into which the
sensor has been connected. The front panel 10-segment LED voltmeter should indicate near
mid-scale if the sensor and cable are intact and working normally.
In like manner, connect up to the maximum number of sensors and check the bias indications
of each for normal operation. If the monitor voltmeter reads full scale, this means:
1.
That there is no sensor connected to that channel.
2.
The cable to the sensor is open.
3.
The sensor is not functioning correctly.
After ensuring that all channels are functioning normally, connect the ‘Output’ connectors to
the readout instrument using the rear sets of output jacks. You are now ready to proceed with
the measurement task.
Remember, the rear panel BNC monitor jack allows the user to monitor the signal from any
channel selected by the front panel rotary selector switch. Thus, each channel may be
monitored for normal operation, even while that channel is being monitored at the rear output
jack for that channel.
