4.0 Starting up the Instrument
4.1 Power Supply
The Pooltest 9 Bluetooth is designed to be powered
either from alkaline batteries or via the USB port.
When operating on battery power, the battery level
is indicated on the Info Panel. A minimum voltage
of 3.0V is needed to operate the photometer and
a flashing battery symbol indicates a critically low
battery. Change batteries immediately or switch to
alternative USB power. The Pooltest 9 Bluetooth will
automatically power down when power is no longer
capable of providing acceptable performance.
To power via the USB port, use the supplied cable
connected either to the mains adaptor or a PC. The
USB icon will appear when the USB connection is
made and battery power will no longer be consumed.
The Pooltest 9 Bluetooth has a back-up battery
mounted internally to save instrument settings and
data during power loss and instrument idle periods.
4.2 Replacing Batteries
The battery compartment is located on the base
of the instrument and secured by four screws.
Remove the cover and install a complete set of
new batteries, observing the correct polarity as
indicated. Use 3 x 1.5V ‘AA’ alkaline batteries
or equivalent. See Appendix 2 for more details.
To avoid corrosion damage through leakage,
remove batteries from the instrument if it is to
be stored or left unused for a long period.
