4.8.2 Set the TI decade dial control(s) to zero OHMS and maintain POWER switch to ON.
4.8.3 Set resistance measuring system deviation control(s) to zero, and adjust the system detector zero control(s)
for a null indication on the detector meter. Change the detector range setting as required for detector sensitivity.
4.8.4 Set the resistance measuring system output switch to (plus), refer to table 2, and set the measuring
system multiplier dial as required.
4.8.5 Adjust the measuring system decade resistance dials to obtain a null indication on the detector meter.
4.8.6 Set the measuring system function switch to lead adj, and adjust the lead adjust controls as required to
compensate for lead and terminal resistance, increasing the detector sensitivity as required.
4.8.7 Set the measuring system function switch to yoke adj, and adjust the yoke adj control(s) for a detector
null, increasing the detector sensitivity as required.
4.8.8 Set the measuring system function switch–to NORMAL.
4.8.9 Adjust the decade resistance dials for a null indication on the detector meter, and note indication of
decade dials.
