3.3.6.2 TEST PROCEDURE. Refer to Figures 3-5, 3-6, 3-7, and 3-8. Check cable as follows:
a. Verify Tester is OFF
b. Set DMM to resistance mode.
c. Measure self-resistance of DMM.
d. Make sure to subtract DMM self-resistance from result.
e. Connect DMM between TP5 and TP6.
f. Set S1 to position A. Verify resistance is less than 1.0
Ω
.
g. Set S1 to position B. Verify resistance is less than 1.0
Ω
.
h. Set S1 to Position C. Verify resistance is less than 1.0
Ω
.
i. Set S1 to position E. Verify resistance is less than 1.0
Ω
.
j. Set S1 to position F Verify resistance is less than 1.0
Ω
.
k. Set S1 to position A.
I. Turn power supply on. Turn Tester on.
m. Verify only LED A is on.
n. Set S1 to position B. Verify only LED B is on.
o. Set S1 to position C. Verify only LEDs C1 and C2 are on.
p. Set S1 to position E. Verify only LEDs E and F are on.
NOTE
Oscilloscope and function generator must NOT both be grounded at their
115V power input or the LEDs of E and F remain “ON” in “IDLE” position.
q. Set S1 to position F Verify only LEDs E and F are on.
r. Set S1 to position idle. Verify no LED is on.
s. Turn off power supply.
t. Measure resistance between TP6 and TP5. Verify resistance measured is 2
±
1.25
Ω
.
u. Measure resistance between TP4 and TP2. Verify resistance measured is 114.5
±
1.5
Ω
.
v. Set function generator to square wave of 1 MHz and 20
±
0.5 Vp-p amplitude.
w. Measure signal with scope. Verify square wave amplitude is 28
±
0.75 Vp-p and
frequency is 1 MHz
±
1 Hz.
x. End of test.
