99 • Calibration
14 . The SDM-6000 will then apply calibration gas in the order of the instrument’s
sensors for the length of time defined in the GAS calibration parameter. For
example, if you are calibrating a 4-gas + low range PID instrument, gas will be
applied to the 4-gas sensors and then gas will be applied to the low range PID
sensor regardless of what SDM-6000 inlet fitting those gas cylinders are
assigned to. The only exception is that HCN will always be applied before any
other gas. The SDM-6000 will analyze the results after the end of each gas
application.
15 . A post-sample purge will begin.
16 . If the Alarm Check calibration parameter is selected, an alarm check will
begin. The buzzer will sound, the LEDs will turn on for a few seconds, the
vibrator will vibrate, and the SDM-6000 will determine if these actions were
completed successfully.
17 . Once the calibration is over, the Function Tab will display a CAL End button. To
view the test results, press the Unit button to display the Unit Tab. The
displayed results will alternate between calibration results and alarm check
results. The test results will display on the Unit Tab until you press the CAL
End button in the Function Tab even if the GX-6000 is turned off.
18 . If a printer is connected:
a. If Auto Print is selected, the calibration results will automatically print.
b. If Auto Print is not selected, a Print button will appear in the Function
Tab’s Calibration screen. Press the Print button to print the calibration
results.
19 . Press the Function Tab to display the Function Tab if it is not already
displayed. Press the CAL End button to return to the top level Function Tab
screen. The test results that were being displayed in the Unit Tab will
disappear once the CAL End button is pressed.
20 . To perform any other operations, press the BUMP, CAL, or Alarm Check
buttons on the Function Tab.
21 . To turn the GX-6000 off:
If the calibration was successful, the GX-6000 will shut off after 15 seconds. If
the calibration failed, the GX-6000 will shut off after 10 minutes. If buttons are
pressed before the SDM-6000 turns off the instrument, the station will
automatically turn the instrument off 10 minutes after the last button push.
To turn off the GX-6000 before it is automatically turned off, press the Detector
Off button in the lower left corner of the Unit Tab. If you have a multi-station
installation, only the master (leftmost) station will have a Unit Tab. The slave
stations will only have a main screen and the Detector Off button will be
displayed in the lower left corner.
22 . The results of the calibration will be stored in the SDM-6000’s SD card.
23 . Push the red gas in/gas out cover toward the GX-6000 and then release it. It
