    Chapter 6: Operation Overview The SDM-3R is capable of performing bump tests, calibrations, and alarm checks on the GX-3R (Pro). It can also charge the rechargeable Li-ion battery pack in the GX-3R (Pro). This chapter describes procedures for using the docking station to bump test, calibrate, alarm check, download instrument logger data to a USB drive, and recharge GX-3R (Pro)s.

  • Page 53: Bump Testing

    SDM-3R. Bump Testing When a bump test is performed, the SDM-3R performs a fresh air adjustment on a GX-3R (Pro) and then applies calibration gas to the instrument. The docking station then analyzes the response and determines if the instrument passed the bump test based on the bump test check tolerance setting (see pg.
  • Page 54 SDM-3R’s pump will keep running. 11 . The SDM-3R will analyze the results after the end of each gas application. If the bump test fails and AUTO CAL is set to ON, the gas will keep flowing and a calibration will automatically begin.
  • Page 55 13 . If the ALARM CHECK bump test parameter is set to ON, an alarm check will begin. The buzzer will sound, the LEDs will turn on for a few seconds, and the SDM-3R will determine if these actions were completed successfully.

  • Page 56: Calibration

    If a flow failure occurs, confirm all tubing connections are correct, that all lines are clear, and that the GX-3R (Pro) is correctly installed in the SDM-3R. A pre-sample flush will begin. The SDM-3R will apply fresh air to the GX-3R (Pro) for the time defined by the AIR FLUSH calibration parameter.
  • Page 57 If the air adjustment is successful, the SDM-3R will continue as described in step 10 below. b. If one or more of the sensors fails the fresh air adjustment, the SDM-3R will abort the calibration and will not apply calibration gas. The LCD will indicate which channels passed and failed the fresh air adjustment.
