Test Points
These test points are provided on the PCB and the DB9 front panel connector for use
by maintenance personnel
TP100 and TP101
Driver drain current measurement. A multimeter placed across
these pins will indicate 1 volt for 1 amp of Q102 drain current
TP102 and TP103
O/P stage drain current measurement. A multimeter placed
across these pins will indicate 1 volt for 10 amps of Q100 and
Q101 drain current
TP200
PA Temperature reading. 1 volt indicates a temperature of 40
degrees. This reading deviates by 10mV per degree of change
