14.7.2 Test I Channel
Displays current when voltage is applied to test pins. Internal jumpers need
to be changed and an external voltage applied. Move the jumper on JP9 from
pins 2 and 3 to pins 1 and 2. Move the jumper on JP10 from pins 2 and 3 to
pins 1 and 2. Inject up to a 65mV signal on pins 10(+) and 12(–) on the test
lead connector. Input voltage must not exceed 65mV. The display indicates
1 Amp for each 1 mV. Replace the jumpers to their original positions after
testing. Do not use this diagnostic for calibration.
14.7.3 ICr Channel
Displays the voltage connected to the black clip and the red/black sense clip
on the resistance (three lead) lead set. This input is for the voltage reading
across the intercell connector under a test condition. Input voltage must not
exceed 130mV.
14.7.4 A/D Reference
Displays the internal reference for the analog to digital converter. The raw
count A/D value should be approximately 10000.
