Alid)'NE INQINaUUNG COIIPO-TION 5.4.4 Adjust the amplitude of the function generator output for a 16V peak-to-peak display on CH 1 9f oscilloscope; note amplitude of display on CH 2 of oscilloscope.
5.4.5 Raise the frequency of the function generator until! the display is 11.3V peak-to-peak on CH 1 of oscilloscope. (Make sure amplitude on CH 2 is the same as in step 5.4.4) this should occur at 10+/-2.5Hz. Indicate acceptance on test report with checkmark.
- 5.4.6 Set function generator output to 30 Hz., as indicated on the frequency counter; adjust the amplitude of the function generator output until the CH 2 display on oscilloscope is the same as noted in 5.4.4., and observe that the display on CH 1 of oscilioscope is 930 +/- 300 mV peak-to-peak . .,.
Indicate acceptance on test report with checkmark.
5.5 Remote Calibration Circuit 5.5.1 Connect DMM to MC! OUTPUT A and set DMM to read DC volts.
5.5.2 On PT174-1-Q2, connect pin 28 of connector (Figure 1) to signal ground (Pin 24); the output indication on DMM should be 5.750+/-0.220V. Indicate acceptance on test report with checkmark.
5.3 Remove Ground from pin 28 of PT174-l-Q2 connector.
6 Current Consumption 5.6.1 Connect the DMM leads"to the MCI *+15V current and voltage test jacks (Figure 5); set DMM to read DC mA.
5.6.2 Set the MC! +15V I TEST switch (Figure 5) to +15; the DMM indication should not exceed 22 mA. Indicate acceptance with checkmark on test report.
- 5.6.3
- Set the MC! +15V I TEST switch to the unmarked position; disconnect the DMM leads from the MC!.
5.6.4 Connect the DMM leads to the MC! -15V current and voltage test jacks (Figure 5).
5.6.5 Set the MC! -15V I TEST switch (Figure 5) to -15; the DMM indication should not exceed 22 mA. Indicate acceptance with checkmark on test report.
5.6.6 Set the MC! -15V I TEST switch to the unmarked position; disconnect the DMM leads from the MC!.
5.6.7 Unplug PT174-l-Q2 from extender card cable connector.
