3.2.3 Pump low flow alarm Please refer to the User Manual supplied with the pump for further instructions and safety precautions regarding the proper use of the pump. 3.3 Sample-draw probe The IQ Force’s sample-draw probe is the standard probe assembly from Honeywell Analytics. The sample-probe handle contains moisture barrier and particulate filters designed to remove contaminants that might otherwise harm the instrument. Particulate contaminants are removed by means of a cellulosic filter. The hydrophobic filter includes a Teflon barrier, which blocks the flow of liquid/ condensate (moisture) as well as any remaining particulate contaminants. Sample-probe filters should be replaced whenever visibly discolored due to contamination or blocked to the extent of failing the pump leak test. 4. Calibration The accuracy of the IQ Force should be verified on a regular basis. Verification can be as simple as performing a calibration accuracy check or bump check, which is described below in Section 4.1 . The IQForce has been shipped with a default calibration interval of 30 days. The day calibration interval provides the IQManagement software with the multiple sensor sensitivity datapoints required for effective predictive maintenance features. If you are not using the predictive maintenance features in IQManagement system, or do not wish to calibrate your detector as often, Honeywell Analytics recommends that the detector be calibrated at least once every 180 days.
