REAR PANEL CONTROLS - Fig. 3-2
H. RECORDER OUTPUT:
Output is 0V±3V for full scale. A BNC connector is provided on the rear panel.
The output voltage is equal to the voltage measured divided by 1000. Minimum
load resistance is 1k ohm.
I. MASTER JACK:
Allows other units with slave connections to be operated by this unit. The output
provides a switch closure when the front panel standby/operate switch is in the
OPERATE position.
J. SLAVE JACK:
Input for remote enable/disable of the high voltage section. In STANDBY a
closure between the center and outer conductors of the plug will enable the high
voltage if the probe is attached and the fork oscillating. The remote can be
overridden by switching the front panel switch to either OPERATE or OFF. The
switch should be capable of handling 30V open and n x 10mA, where n is the
number of units being controlled.
K. POWER ON/OFF SWITCH:
Main power to instrument is on when red ring is visible on side of rocker.
L. GROUND JACK:
5 way binding post connected to power line ground to provide system ground.
M. FUSE DRAWER:
Contains fuses and line voltage switching selector insert. Refer to "CAUTION"
