b. Adjustments
(1) Turn LO RF UV dial to 10 KUV and adjust LO-HI RF SET TO LINE control
for a 10.00 mV indication on measuring receiver.
(2) Adjust R61 (LO RF METER CAL) for a red-line indication on IF MV RF SET
TO LINE meter (adjustment is located on right end on bottom chassis) (R).
10. High RF Voltage Range
a. Performance Check
HI-RF, using cable No. 2.
NOTE
At each of the following tests, adjust LO-HI RF SET TO LINE
control to maintain red line indication on IF MV RF SET TO
LINE meter.
(2) Set RF OUTPUT switch to 62.5 KUV and BAND SWITCH to B and 30 MHz.
If measuring receiver does not indicate within the limits shown in first row of table 6,
perform b below.
