Meter
The meter is presented in one of two styles to indicate the gas reading,
“Normal”, and “% FS”. The “Normal” style divides it into three colored bands,
based on the alarm settings. The “% FS” style indicates only the sensor full
scale range, ½ full scale range, and 0. This is designed for applications not
intended to have alarms. See Meter in Display Operation on page 19 for
details about the meter operation and configuration.
Battery Indicator
The battery indicator displays the voltage of the battery, which can be
used to approximate the level of charge remaining.
