3. 34 Alicat Portable Meters and Gauges Alicat Portable Flow Meters and Gauges use a common 9 Volt battery located in the top section of your meter Output signals from the flow meter are passed through the female connector on top of the flow meter Turn the switch on top of the flow meter off when the meter is not in use Normal 9V alkaline battery life is approximately 8 hours 30 40 hours with a 9V lithium battery however many factors can affect this Note Alicat recommends the use of non rechargeable 9V lithium batteries in all MB TFT color display portable meters and gauges Replace the battery as often as required A yellow LED indicates low voltage and that the battery should be replaced A false signal can result when the voltage drops below its normally regulated level Alicat Portable Flow Meters and Gauges can also be powered by an optional AC DC plug in wall adaptor With the adaptor plugged into the flow meter the battery is bypassed and the meter will operate solely off the adaptor power supply Replacing the Battery 1 Remove the four Phillips head screws from the front cover and gently remove it as shown below Remove the 9V battery pulling the top of the battery out first Disconnect the old battery from the harness and replace it with a new battery Install the new battery bottom end first and replace the back cover so that the cushioning pad presses directly down on the battery 5 Replace the f
