STATIC MEASUREMENTS
With the power turned OFF, connect the VOM to your
circuit as shown in Figure 28. Connect a clip lead from
test point two (TP2) to the collector of Q1. This short
prevents Q1 from oscillating. Set the VOM to read 2 volts
DC accurately and turn the power ON. The DC voltage at TP1 should be 1.6 volts. If the voltage in your circuit differs
by more than 0.5 volts, leave the power ON and check
the battery voltage. If the battery voltage is greater than
8.5 volts, turn the power OFF and check components R1,
R2, R3 and Q1.
