The TIF 8800 Combustible Gas Detector shall not be used to detect Carbon Monoxide

Question 3

• Turn sensitivity knob fully counter clockwise.
• In a non-contaminated atmosphere, slide the power switch to the on position. The power light should be lit. No sound will be heard.
• After a 30 second automatic warm up, a ticking sound will be heard.
• Adjust the sensitivity control until a rapid ticking is heard (Hi Sensitivity).
• Search the general area of the leak. When a detectable compound enters the probe, the tick rate will increase until a siren level is heard, usually at the point of leak.
• In most cases, it will not be necessary to adjust the sensitivity of a detector. However for extremely small leaks, turn the sensitivity knob to the Hi position (rapid ticking). For large concentrations, desensitize the detector by turning sensitivity knob counter clockwise to the Lo position.
• Failure to maintain a steady click or lack of the power light being lit may indicate what?
