INTEGRATING AMPLIFIER WITH RELAY CONTACTS
When the OPERATION switch is in the RESET position, the relay contacts are all closed.
Connect the two binding posts on either end of the feedback socket to the two relay contacts 1,
as shown in Figure 21. Set IC-1 to 5 volts and connect to the input of am plifier 1, to which the
1 megohm resisto r was connected. Turn the OPERATION switch to MANUAL. The m eter read
ing should increase rather uniform ly from z ero to approximately 100 V, but should be stopped
at 60 volts by turning the OPERATION switch to RESET. This will stop integration and rem ove
the charge from the capacitor, leaving it ready for operation again. Turning the OPERATION
switch to REPETITIVE w ill start the computer operating, but now the oscilla tor w ill automati
cally reset the initial conditions and start solution again at a rate control by the REPETITION
RATE control. This operation w ill continue until the OPERATE switch is returned to RESET.
