(5) Adjust FREQ potentiometer A2R69 (fig. 1) to obtain maximum indication on TI
digital readout and verify that frequency counter indicates 220 Hz (R).
(6) Repeat a above, and if TI does not indicate within limits specified, perform (7)
through (18) below.
(7) Disconnect counter from TI.
(8) Connect multimeter to TI RECORDER OUTPUT (rear panel).
(9) Set range calibrator FUNCTION switch to STANDBY and RANGE
switch to 1 mW.
(10) Press SENSOR ZERO pushbutton and wait for display readout to stabilize.
Release SENSOR ZERO pushbutton and wait for ZERO light to extinguish.
(11) Set range calibrator FUNCTION switch to CALIBRATE and adjust front panel
(12) Adjust LIN potentiometer A3R37 (fig. 1) until TI digital readout indicates
1.000 mW (R).
(13) Press MODE and RANGE HOLD pushbuttons to dBm and ON respectively.
NOTE
The next step sets the A-D log threshhold. When specified
indication (-10.00) is obtained, digital readout should be just on
the verge of blanking, that is, readout may randomly alternate
between -10.00 and under range, -1.
(14) Set range calibrator RANGE switch to -10 dBm and adjust LZR A3R59 (fig. 1)
for -10 dBm (R).
(15) Press RANGE HOLD pushbutton to OFF and range calibrator RANGE switch
to 1 mW.
(16) Adjust LFS potentiometer A3R48 (fig. 1) until TI digital readout indicates
-0.00 (R).
(17) Press MODE pushbutton to WATT and adjust MTR A3R17 (fig. 1) until pointer
is half-way between last two marks on meter face (R).
a. Performance Check
(1) Connect range calibrator to TI POWER SENSOR cable supplied with TI.
