By default, the Quarryman Pro is connected to the standard lithium-ion battery supplied. If a lead acid battery is
used instead, whether with the blue crocodile clip cable or the main power cable, you will need to press the
5
button
on the keypad for three seconds when powering the Quarryman Pro ON. Alternatively, from the main menu, press
the
FUNCTION
key and
5
key together to toggle the battery selection between lead acid and lithium-ion.
It is necessary to carry out this procedure because of the different voltages and discharge profiles of lithium-ion and
lead acid batteries. If you do not identify the battery as lead acid, the Quarryman Pro will assume that it is connected
to a discharged lithium-ion battery. In this case, very soon after it is turned on, the Quarryman Pro will display a low
battery warning and carry out a controlled shut-down.
The battery type will be displayed on the start-up splash screen. It will also be displayed on the battery indicator in
the status bar as either Pb (lead acid) or Li (lithium-ion).
If a lead acid battery is being used at a voltage of less than 10.8 V dc, the Quarryman Pro will carry out a controlled
shut-down due to low power.
Any voltage source connected to the Quarryman Pro must be within the specified voltage range. This
includes car batteries as an acceptable stand-alone power source but does not include a car battery
connected to a powered vehicle, or a dc power generator.
4.10 USB drives
Three USB drives are supplied with the Quarryman Pro. During all operations with the Quarryman Pro, data is
stored in a USB drive inserted into the instrument.
The USB drives fit into the USB port on the side of the Quarryman Pro.
The USB port is sealed and waterproof. A rubber plug with lanyard is connected to the Quarryman Pro and can be
used to physically protect the USB drive when no USB drive is connected to the unit.
