If batteries are accidently installed in the wrong polarity, a positive temperature coefficient (PTC) thermistor will protect the instrument’s electronic circuitry. 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.
4 OPERATION To operate the Monoxor II, you simply . . . • Set its POWER switch to ON, • Wait for the instrument to warm up (approx. 1 minute), • Zero the display (if necessary), • Take a gas sample. Detailed operating procedures are presented below: 4.1 Power ON/OFF Turn on the instrument by sliding its POWER switch to ON. Observe that when power is first applied, all numerical LCD segments are tested for 5–15 seconds; after which, the LCD shows the detected CO level.
4.3 Backlight ON/OFF The LCD can be read in low-light areas by setting the front panel LIGHT switch to ON. The backlight stays on until turned off, or until the POWER switch is set to OFF. 4.4 Using the Strap The instrument's elastic strap allows the unit to be either hand-held, or hung on nearby objects. By sliding your hand between the instrument and its elastic strap, you can hold onto the Monoxor II with a minimum of effort.
Overrange When the gas sample exceeds 1999 ppm, a “1” is displayed on the LCD. To clear an overrange condition, leave instrument turned on and sample fresh air until the LCD returns to displaying CO. Low Battery Indications When the battery voltage becomes low, the “LO BAT” indicator appears. Although the instrument will continue to operate and give CO readings under these conditions, the batteries should be replaced as soon as possible.

7 HAZARDS OF CARBON MONOXIDE Carbon monoxide poisoning results in headache, nausea, chronic tiredness, confusion, dizziness, and sometimes coma or death. It effects people by cutting off the supply of oxygen to their muscles and brain. The harmful effects of carbon monoxide exposure depend on both the concentration of CO in the air and the length of exposure. Concentration of CO in air Inhalation time and toxic symptoms developed 50 ppm* (0.
