displayed. If this occurs, a qualified electrician should check all system
voltages.

U1: 5.9V
6V nominal value. 5V to 7V acceptable range
Supply Voltage:
Supply voltage on the -6V branch line
U2: -6.1V
-6V nominal value. -5V to -7V acceptable range
Supply Voltage:
Supply voltage on the 12V branch line
U3: 12.5V
12V nominal value. 10V to 17V acceptable range
A voltage measurement below the acceptable range and close to zero may be
indicative of a short-circuit or a system overload. If much higher values appear, a
parasitic voltage from an external source in the system may be reaching the
device.
