CALIBRATION PROCEDURE 067-0587-01
d. Connect the Precision 50 2 Terminators to the "A-11 VERTICAL"
and "B-11 VERTICAL" lines of the Signal Pickoff device using Tektronix
to GR adapters. Connect the free end of the "A-11 +VERTICAL" Precision
502 Terminator to the +DVM input using GR to BNC adapters and BNC to post
adapter. Connect the free end of the "B-11 VERTICAL" Precision 502 Ter-
minator to the -DVM input in the same manner. Refer to Fig. 1 for setup
information.
e. Remove transistor Q118 and connect the Stepper Circuit shown in
Fig. 2 between the collector pin of Q118 socket and ground. This allows
the gain staircase to be stepped manually. |

f. Mechanically center the Signal Standardizer control. Press and —
release the Stepping Circuit switch and note that the DVM reading changes.
Continue tapping the switch until a DVM reading of approximately 0.00 mV
is obtained. Adjust the POSITION control for a DVM reading of 0.00 mV +
+0.05 mV.
g- Tap the Stepping Circuit switch until the 50 mV range is obtained.
Record the DVM reading and correct it for power supply errors. Check that
the corrected reading is within 0.3% of the range.
h. Repeat step g for the 100 mV, 150 mV, 200 mV, 250 mV, -50 mV,
-100 mV, -150 mV, -200 mV, and -250 mV ranges.
