Battery and Trunk Voltage Measurement
The Model Two is equipped with a built-in voltmeter that can be used to troubleshoot problems
with power supplies or power drops. The Model Two accommodates AC or DC voltages up to
100 Volts. To enter the Voltage screen, press
VOLT
.
The Voltage screen displays two bar graphs.
The top bar graph indicates the battery charge of your Model Two. This approximate charge level
and the battery voltage are also displayed numerically. As you use your unit, you can access this
screen to check the remaining battery power.
When the battery charge drops below 10%, the battery symbol
flashes
in the information line at
the top of the display screen. If the charge drops below 5%, the Model Two shuts off automatically
to protect the battery. (See
Battery Charging
on Page 20.)
The lower bar graph indicates the AC or DC voltage of the system’s trunk.
The Model Two automatically detects the presence of an AC or DC voltage and displays the
measurement graphically and numerically.
The voltmeter specifications are:
Input Range
1.0 - 100 VDC, 1.2 - 100 VAC
Resolution
0.1 V
Accuracy
+/- 1.0 V
