3.8 Removing the Temperature & Humidity
Sensor Probe
If desired, the Temperature & Humidity Sensor Probe (Figure 1, Item D)
can be removed and the instrument used to primarily measure just gas.
Important! With the probe removed, the temperature and
humidity readings should be disregarded. All other readings
are valid.
Note: If the probe is reinstalled with the instrument switched
ON, observe that ‘BattLow’ may briefl y appear even with a
fully charged battery. This is normal and does not indicate
that the battery needs recharging.
Remove the probe as follows:
1. Switch OFF the instrument.
2. Unlock the probe by aligning the
dots on the probe’s locking collar as
shown in Figure 3.
3. Remove the probe by pulling it
straight up.
Install the probe as follows:
1. Switch OFF the instrument.
2. If not already done, turn the probe’s locking collar so that all the dots
line up.
3. Align the dot on the probe with the dots on the instrument; then push
the probe into its socket until it bottoms out.
4. Lock the probe into place by turning the locking collar to its locked
position.
