indication.
amplitude as required.
(4) Adjust test oscillator amplitude for a 0-dB indication on TI meter 0 to 10 dB
scale. Test oscillator output meter will indicate 0.3 V or less.
(5) Vary output of autotransformer (A3) from 105 to 125 V while maintaining 0 dB
indication on TI meter. Test oscillator output meter will indicate 0.3 V or less.
(7) Adjust test oscillator amplitude for 0.04 V and record TI meter indication.
(8) Remove equipment-setup and connect termination (B7) to TI INPUT.
(9) Set SWR-DB switch to 60. If TI meter does not indicate less than (down-scale)
indication recorded in (7) above, perform b below.

Adjust R39 (fig. 1) for minimum
down-scale indication on TI
(R).
