281.
Set ANALOG SIGNALS ATT synchro (38) to 1.0.
Read and record V13 AC/DC VOLTMETER (10)
reading.
282.
Set ANALOG SIGNALS ATT synchro (38)
to 359.0 . Read and record V14 AC/DC
VOLTMETER (10) reading.
283.
Calculate V15. Subtract reading of step 282 from
reading of step 281 (V15 = V13 - V14). Result
shall be +3.80 to +4.65 volts.
284.
Set ANALOG SIGNALS ATT synchro (38)
to 356.0 . Read AC/DC VOLTMETER (10).
Reading shall be -4.89 to -7.03.
285.

0.0 . Read AC/DC VOLTMETER (10). Reading
shall be -0.64 to +0.64.
289.
Set ANALOG SIGNALS ATT synchro (38) to
1.0 . Read and record V16 AC/DC VOLTMETER
(10) reading.
290.
Set ANALOG SIGNALS ATT synchro (38)
to 359.0 . Read and record V17 AC/DC
VOLTMETER (10) reading.
291.
Calculate V18. Subtract reading of step 290 from
reading of step 289 (V18 = V16 - V17). Result
shall be +4.94 to +6.04.
