NOTE Rechargeable batteries will provide substantially fewer hours of operation and will self discharge while the instrument is in storage Users should also be aware that use of rechargeable batteries will void the CSA approval of the MiniBump for intrinsic safety Microprocessor Based Circuitry When powered up the microprocessor checks for what type of generating source is inserted the gas type and concentration as well as if the source is a bump type source and the remaining source life It also monitors battery life and indicates when either a low battery or exhausted source condition occurs The circuit board is attached directly to the bottom case via solder joints to the battery terminals If damaged or inoperable it should be replaced as part of the case rather than removed from these terminals 6

III NORMAL OPERATION MINIBUMP SOURCE The instrument is designed to generate gas for approximately 36 seconds per bump test Each source will provide up to 1000 tests The MiniBump will generate gas until either the battery becomes discharged or the source is consumed If either condition occurs a RED LED will light indicating a non normal condition refer to the Non Normal Operation section that follows The calibration gas is delivered through a small flexible hose attached to the source manifold cap The hose is placed over around or in front of the gas sensor Alternatively the detector can be placed directly in front of the outlet fitting allowing the gas to be presented directly to the detector 8

IV START UP MINICAL SOURCE To start the generator press and hold the ON OFF Switch located in the middle front of the instrument until the GREEN LED turns on approximately 3 seconds Release the switch immediately thereafter The GREEN LED will blink at a rapid rate indicating the number of hours of gas remaining in the source 5 blinks indicate 5 hours of life remaining It will then blink at a rate of once a second for approximately 20 seconds Gas will begin to be generated immediately After 20 seconds the pump will come on and the unit will continue running with the green light blinking for an additional 20 seconds After this the green light will stay illuminated indicating the unit is ready to calibrate With a MiniCal source installed the unit will continue to run in this state generating the concentration and type of gas specified by the generating source installed until turned off by pressing the power button for an additional 3 seconds When the unit is turned off it will enter a purge cycle both red and green lights will alternate indicating that the instrument is purging It will shut off automatically after an additional 25 seconds Note Some sensors have faster response times than others Leave the MiniBump calibrator attached to the sensor until the sensor has stabilized and then proceed with the calibration procedure for that sensor If the RED LED begins flashing or remains lit continuously it indicates the instrument is in either low battery condition or source failure mode Please refer to the section on Non Normal Operation 9
