Check dc 
output voltage 
• Measure at TB1(+) and TB1(-) using a dc
voltmeter. Value should agree with front 
panel voltmeter within 0.25%, and must 
be correct values for your battery. If the 
AT10.1 is using a temperature 
compensation probe, see the graph on 
page 23 to determine correct battery 
voltage. You need to know the battery 
temperature for this step.
