FEBC Operation

Page 6

E. Connect a voltmeter between the AN2 terminal and any RET terminal on connector P4. Adjust Potentiometer

R20 for the desired full-scale output voltage.

F. Connect a voltmeter between the AN3 terminal and any RET terminal on connector P4. Adjust Potentiometer

R21 for the desired full-scale output voltage.

G. Connect a voltmeter between the AN4 terminal and any RET terminal on connector P4. Adjust Potentiometer

R22 for the desired full-scale output voltage.

H. Reset the option dipswitch from the CALIBRATE function. Set switch #7 on S4 to the 'off' position.

I.

Cycle power off and on again to remove FEBC from calibrate mode. All analog outputs will reflect incoming
signals or be set to zero levels.
