Time-Weighted Average (TWA)
The TWA function shows the average reading for toxic gases during

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

Note
The GX-82A automatically checks battery voltage during
start-up; if the measurement is below 2.3V, the GX-82A will
not operate.
