Check dc output
voltage
• Measure at TB2(+) and TB2(-) using dc voltmeter. Value should agree
with front panel voltmeter within 2%, and must be correct values for
your battery. If the charger is using a temperature compensation probe,
see the curve in Section VII of user's manual to determine correct
battery voltage.
