19. Calibration Procedure (continued)

3.

You must check for air leaks before calibrating. Apply a gas with
0% O2 to check for air leaks (ECOM service dept. uses NO gas
balanced in N2). Flow calibration gas for 3 minutes. Check that
O2 reading is 0.0%. If it is reading other than 0.0 %, turn off gas
and troubleshoot the source of air leak. Do not proceed to
calibrate analyzer until air leak is corrected.

4.

If there is no air leak, allow gas to flow for another 2 minutes
(total of 5 minutes). After the reading has stabilized, press
up/down to place the arrow beside the target sensor and press

OK

to go to input mode. Input concentration of calibration gas

using numbers on keypad. Press

OK

. The sensor has now been

calibrated.

5.

Allow the gas to flow for another 45-60 seconds. If it does not
drift more than 2% of the span gas, the calibration is steady and
you may disconnect the gas. (If it does drift more than 2%, allow
the reading to stabilize and reset calibration. If this still doesn’t
work, call ECOM.)

6.

If calibrating more than one sensor, disconnect the regulator
and reconnect to the next gas cylinder. Then flow calibration gas
for 5 minutes, input calibration setting, & repeat step 5.

7.

After all sensors have been calibrated, disconnect gas and allow
the analyzer to flush with fresh air for 10 minutes or until
readings are below 10 ppm.
