This article applies to all Field Gauge LC20 and Process Meter LC30 models equipped with a Bluetooth radio.
To determine if your gauge is Bluetooth enabled: Check the last two characters in the model number printed on the gauge. If they are "B1", the gauge can communicate wirelessly with Bluetooth.
Each time you power on a Bluetooth-enabled gauge, the Bluetooth radio will be ON by default.
You may choose to reduce battery power consumption on your gauge by turning off the Bluetooth radio.
