If batteries are accidently installed in the wrong polarity, a positive

temperature coefficient (PTC) thermistor will protect the instrument’s

electronic circuity. The instrument will operate once batteries are

properly installed and the PTC thermistor is allowed to cool.

3.2 Probe Installation

Install the probe by sliding the end of its tubing over the gas inlet

port on the top right side of the instrument as shown in Figure 3. The

tubing may be difficult to slide over the gas inlet port of the unit for

the first time. This was done intentionally to allow for a snug fit. Use

a little dish washing liquid diluted in water or heat the end of the tube

in hot tap water to help it slide onto the port.
