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.
