5-35. X Drive Final Voltage Adjustment.
5-36. This adjustment sets the final voltage of the X drive ramp to + 10.5 Vdc.
Required Equipment:
dc voltmeter
-hp- Model 3466A
a. Connect the dc voltmeter to the -hp- 3336 X Drive output.
b. Starting with the -hp- 3336 in turn-on condition, set the Sweep Time to .999 seconds.
c. Press the -hp- 3336 SINGLE key twice. The first actuation resets the sweep to the start
conditions and the second starts a single sweep.
[x
d. At the end of the sweep, the dc voltmeter should read +10.5 Vdc, +.05 V. If the
r
og
voltmeter reads less than + 10.5 Vdc, adjust A4R6 slightly clockwise. If the voltmeter reads
more than +10.5 Vdc, adjust A4R6 slightly counterclockwise.
NOTE
The voltmeter will not respond directly to the adjustment of
A4RO6. The effect of the adjustment can only be seen after another
single sweep.
e. Press the SINGLE key twice to execute another single sweep.
f. Readjust A4R6 and execute single sweeps as necessary until the end voltage is + 10.5
Vdc, +.05 V.
g. Check the decay rate of the X Drive voltage. The final voltage should decay at less than
10 mV/second.
