RKI Instruments SDM-E2 - Manual (Page 62)

57 • Calibrating an Instrument with Special Sensors
WARNING: Do not plug the charger cable into a battery pack that contains alkaline
batteries. Do not attempt to charge alkaline batteries.
7. Press and hold the POWER ENTER RESET button on the EAGLE 2 until you
hear a beep, then release it. The EAGLE 2 will begin its power up sequence. If
a successful connection between the EAGLE 2 and the SDM-E2 occurs, the
home screen will display at the end of the start up sequence. If the charge LED
was amber, it will begin to blink green. The example screen below shows a
standard 4-channel EAGLE 2 that also includes an IR CO
2
sensor in channel 5
and an ESM-01 NH
3
sensor in channel 6. The GAS 2 to the right of the CO
2
and NH
3
channels indicate that the GAS 2 fitting will be used for these
channels.
NOTE: If your EAGLE 2 has less than 4 standard channels, only one special
sensor, or different special sensors, your gas names and auto
calibration values will be different. All screens in this section assume a
channel setup as shown above.
8. Verify that the appropriate calibration gas cylinder is connected to the GAS 1
and GAS 2 fittings on the back of the SDM-E2. See “Connecting Calibration
Gas” on page 24 for calibration gas cylinder options and calibration gas
connection procedures.
9. Connect the gas out to EAGLE 2 line to the inlet fitting on the EAGLE 2.
NOTE: If you have an EAGLE 2 with an IR CO
2
sensor in the 0-10,000 ppm or
0-5.00 %vol range, be sure to replace the air filter at the AIR inlet fitting
with the CO
2
scrubber when testing an instrument with a CO
2
sensor
installed to ensure that the CO
2
present in fresh air is scrubbed out.
Remove the black end caps from each end of the scrubber before
installing onto the AIR inlet fitting. Replace the caps when the scrubber
is not in use. See the “Spare Parts List” on page 80 for a scrubber with
a tubing stub.
