Alicat Portable Meters and Gauges
Alicat Rechargeable Flow Meters and Pressure Gauges use a Li-Ion 3.7V cell located in the top
secti on of the device. The Li-Ion cell must not be removed.
Normal batt ery life of a fully-charged cell is 16 hours with a monochrome display or
5 hours with a TFT color display, when the backlight is set to 10.
The batt ery can be charged through either the micro-USB port or the mini-DIN connector.
When the device is connected to external power it will functi on normally while the batt ery
is charging. Charge rates will be fastest through the micro-USB port using the included
power supply or equivalent. The device will charge fastest when it is turned off .
Recharge Time: 3.5 hours with 2A USB supply. The micro-USB port is for charging purposes only.
The green/red indicator LED on top of the device will light up green to indicate that the
unit is charging. The green LED will turn off when the batt ery is charged and the power
switch is turned to “I” for ON.
The indicator LED fl ashes red when the device has about 1 hour of batt ery life remaining. The
LED will fl ash red at a faster rate when the device has about 15 minutes of batt ery life remaining.
It is highly recommended that the device be charged immediately. When the batt ery charge runs
out, the display contrast will turn to 0 and device performance is no longer guaranteed.
Output signals from the meter are passed through the mini-DIN connector on top
of the device. Rechargeable batt ery units do not support 0-10V analog output.
For 4-20mA current output to functi on, the device must be powered through the
8-pin mini-DIN connector. Receiver resistance must be below 250Ω.
Turn the power switch on top of the device to “O” for OFF when it is not in use.
Warning: If the device is left ON unti l the batt ery can no longer power it, the
charge indicator will fall out of sync with the actual charge. The device can be
re-synced by fully charging the batt ery once.
A Batt ery Charge Indicator appears below Tare on the display:
