External Shutoff Voltage
To avoid damaging the internal batteries when the voltage of
an external battery drops too low, the user can set an external
shutoff voltage. The instrument will shut off automatically
when the external voltage drops below this level.
The default level is 10.8 volts, but the user can select a value
in the range 10 to 25 volts by entering the value directly into
the Ext Shutoff Voltage field shown in FIGURE 18-13.
