Bump Testing a Gas Tracer • 60
• When CL RMNDR is set to ON and CL EXPRD is set to NOT USE, if the
Gas Tracer is due for calibration, the instrument will show a calibration
expired failure screen and the buzzer and LED arrays will pulse.
The Gas Tracer will then connect to the SDM-2012 and display the home
screen shown above in step 8. The CHARGE LED will begin to blink green.
• When CL RMNDR is set to ON and CL EXPRD is set to CONFIRM, if the
Gas Tracer is due for calibration, the instrument will show the following
screen and beep and flash the LED arrays for a few seconds indicating that
calibration is due.
When the beeping and flashing stops, press and release the RESET
SILENCE button on the Gas Tracer to continue. The instrument will now
connect to the program, the home screen shown in step 8 above will be
displayed, and the CHARGE LED will begin to blink green.
10. Verify that the appropriate calibration gas cylinder is connected to the GAS 1
and GAS 2 fittings on the back of the SDM-2012. The ppm calibration cylinder
needs to be connected to the GAS 2 fitting using a 6 inch humidifier tube.
NOTE: If the GAS menu item in Edit Mode is set to Std, the ppm cylinder does
not need to be connected. See “Updating the Tested Sensors Setting”
on page 28 for more explanation of the GAS menu item.
See “Connecting Calibration Gas” on page 32 for calibration gas cylinder
options and calibration gas connection procedures.
