Power the controller from a vehicle
Warning! Use only the supplied vehicle charging cable. Do not plug any other automotive chargers
into the controller power socket.
If the controller has low battery charge, you can still operate it while powering it from your vehicle. The
vehicle charging cable is 18ft (5.5m), but if the survey site prevents you parking the vehicle close to the
manhole or pipe that you need to survey, you can recharge the controller battery from your vehicle.
Use the supplied vehicle charging cable to connect the controller to your vehicle’s DC power connector
(typically the cigarette lighter or cigarette charging point). The controller’s power socket is on the main
connection panel on the rear of the controller; see page 89.
How long does it take to recharge the battery from my vehicle?
This depends on several factors, including whether the controller is powered on and the condition of your
vehicle battery. Also, some vehicles switch off the DC power connector while the ignition is off.
But as a rough guide, if the controller is powered off, then 60 minutes of recharging from your vehicle’s
DC power connector (for example, while driving to the survey site or during a lunchbreak) can restore the
controller battery level by up to 25%.
Consider also the power management options to preserve battery life; see page 90.
