21 M2 Rig Monitor Operator’s Manual
Low Power Condition
The 12 VDC battery that is recommended for operation of the Rig Monitor is typically
dead before the power converter recognizes a low power condition. As a result, when the
Rig Monitor is used with a 12 VDC battery, there will be no low power alarm and the unit
will instead shut off once the battery is dead.
