Operating Temperature • The IQ Force’s operating temperature range is printed on the label on the back of the instrument. Use of Honeywell Analytics Gas Detectors outside of the instrument’s specified operating temperature range may result in inaccurate and potentially dangerous readings. Warning and Cautions • Read and understand the Safe Operation Manual before operating the IQ Force gas detector. • IQ Force personal portable gas detectors have been designed for the detection and measurement of potentially hazardous atmospheric conditions • In order to assure that the user is properly warned of potentially dangerous atmospheric conditions, it is essential that the instructions in this reference manual be read, fully understood, and followed. • The IQ Force personal, portable gas detector has been designed for the detection of dangerous atmospheric conditions. An alarm condition indicates the presence of a potentially life-threatening hazard and should betaken very seriously. • In the event of an alarm condition it is important to follow established procedures. The safest course of action is to immediately leave the affected area, and to return only after further testing determines that the area is once again safe for entry. Failure to immediately leave the area may result in serious injury or death. • Do not charge the IQ Force with any charger other than the appropriate IQ Force charger supplied with the instrument. • The IQ Force must be located in a nonhazardous location during the charging cycle. The IQ Force’s battery charger is not approved for use in hazardous locations. • The IQ Force contains a Lithium-Ion battery. This battery is not replaceable by the user. In the event that the battery becomes unusable, the instrument must be returned to an authorized service center and the battery and associated parts replaced as an assembly. • The accuracy of the IQ Force should be checked periodically with known concentration calibration gas. Failure to check accuracy can lead to inaccurate and potentially dangerous readings. (The Canadian Standards Association (CSA) requires an accuracy check using known concentration calibration gas prior to each day’s use.) • Fresh air/zero calibrations may only be performed in an atmosphere
IQ Force™ Gas Detector Reference Manual vii that is known to contain 20.9% oxygen, 0.0% LEL and 0 ppm toxic gas. • Pellistor-based LEL sensors are susceptible to mechanical shock. The accuracy of the IQ Force should be checked immediately following any known exposure to contaminants by testing with known concentration test gas before further use. Failure to check accuracy can lead to inaccurate and potentially dangerous readings. • The accuracy of the IQ Force should be checked immediately following any physical shock. Failure to check accuracy can lead to inaccurate and potentially dangerous readings. • A sensor that cannot be calibrated or is found to be out of tolerance should be replaced immediately. An instrument that fails calibration may not be used until testing with known concentration test gas determines that accuracy has been restored, and the instrument is once again fit for use. • Do not reset the calibration gas concentration unless you are using a calibration gas concentration that differs from the one that is normally supplied by Honeywell Analytics for use in calibrating the IQ Force. Customers are strongly urged to use only Honeywell Analytics calibration materials when calibrating the IQ Force. Honeywell Analytics offers calibration kits and long-lasting cylinders of test gas specifically developed for easy IQ Force calibration. Use of nonstandard calibration gas and/or calibration kit components can lead to dangerously inaccurate readings and may void the standard Honeywell Analytics warranty. • Substitution of components may impair intrinsic safety. • For safety reasons this equipment must be operated and serviced by qualified personnel only. Read and understand this reference manual before operating or servicing the IQ Force. • A rapid upscale reading followed by a declining or erratic reading may indicate a hazardous combustible gas concentration that exceeds the IQ Force’s zero to 100 percent LEL detection range. • The IQ Force is not designed for use in oxygen-enriched atmospheres. • Do not use a motorized sample-draw pump with the IQ Force for prolonged periods in an atmosphere containing a concentration of solvent or fuel that maybe greater than 50% LEL.
