Calibrating an Instrument
with Special Sensors
When a calibration is performed, the docking station performs a fresh air adjustment
on an instrument and then applies calibration gas to the instrument. The docking
station analyzes the calibration results and determines if the instrument passed the
calibration.
Instruments that have one or more special sensors installed need one or more gas
cylinders to connect to the GAS 2 fitting. Be sure that you have the required
calibration cylinders for your sensors. If you are using a 5-gas cylinder for a special
sensor, be sure that the gas inlet parameters are appropriately assigned as described
in “Setting the Gas Inlet Parameters” on page 21. If your EAGLE 2 has an IR sensor
installed, see “Appendix A: Bump Testing and Calibrating EAGLE 2s with IR Sensors”
on page 83 for a brief description of operation specific to IR sensors.
NOTE: If you wish to calibrate only the standard four sensors or only the
special sensors, be sure that the Gas Inlet Parameters are set
appropriately as described in “Setting the Gas Inlet Parameters” on
page 21.
To perform a calibration on an instrument:
1. Confirm that the AC Adapter is connected to the SDM-E2 and to an AC wall
socket.
2. Press and hold the SDM-E2’s POWER button. The LEDs will turn amber.
3. When the BUMP T and CAL S LEDs turn off, release the POWER button.
4. The COPY LED will be off or on steadily and the CHARGE LED will be blinking
green if the SDM-E2 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-E2 will dictate the condition of
the COPY LED (see “Available Memory in the SDM-E2” on page 68).
