NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check
(1) Set PWR-OFF-BATT switch to OFF and remove battery from TI.
(2) Connect decade resistor across battery terminals.
(3) Set decade resistor for 150 Ω.
(4) Connect multimeter to +18V TP (fig. 9) and chassis ground.
(5) Set PWR-OFF-BATT switch to PWR. If multimeter does not indicate
between 17.6 and 18.4 V dc, perform b (1) below.
(6) Move multimeter positive lead to +15.4 V TP (fig. 9). If multimeter does not
indicate between 15.55 and 15.25 V dc, perform b (2) below.
(7) Move multimeter positive lead to +12.05V TP (fig. 9). If multimeter does not
indicate between 11.95 and 12.15 V dc, perform b (3) below.
(8) Set PWR-OFF-BATT switch to OFF, unplug from power and remove decade
resistor from battery terminals.
(9) Connect dc power supply and multimeter across battery terminals.
(10) Set dc power supply voltage for a 12 V reading on multimeter.
