RED LED will light and the instrument will continue to run for approximately 30 seconds before power down If the cell has been depleted it should be removed and replaced with a new generating cell Please refer to the section on cell life for proper instructions on replacing the generating cells If the cell has not been depleted there may be a faulty electrical connection between the cell and the instrument Remove the cell and inspect the pins protruding from the cell and the sockets in the cell chamber Remove any debris and or corrosion that may be present and retest the cell If either the pins or sockets become damaged or non repairable replace the cell chamber and or the cell Page 6 V Cell Life The generating cell is consumed during normal operation All cells are rated for up to 1000 test maximum 250 minimum Once a cell has been depleted it may be replaced with a new cell to provide another 1000 tests Replacement cells may be stored in their containers in a cool humid area for several years under most conditions Different types of generating cells can be used with each instrument The microprocessor in the MiniBump reads the type of gas of the cell from a memory chip embedded in the cell body It then adjusts itself for each type of gas output For a complete list of correct cell part numbers please refer to the parts list to follow To replace the generating cell in the instrument first remove the instrument cap locat
