Time-Weighted Average (TWA)
The TWA function shows the average reading for toxic gases during
the last 8 hours. If 8 hours has not elapsed since the last time the
STEL/TWA was cleared, the average is still calculated over 8 hours,
with the missing time assigned a 0 value for readings.
Battery Voltage
The Battery Voltage function shows the minimum operating voltage
and present battery voltage.
Note
The GX-86A automatically checks battery voltage during
start-up; if the measurement is below 2.3V, the GX-86A will
not operate.

This function shows the current time, date, and ambient temperature,
for example:
