5 MEASURING PROCEDURE
5-1 Calibration
Before the measurement, the meter should be processed
the following calibration procedures:
1)Disconnect the " OXYGEN PROBE plug " ( 4-21, Fig. 1 )
from the " Probe input socket " ( 4-15, Fig. 1 ).
2)Power on the instrument by pushing the " Power Off/On
button " ( 4-2, Fig. 1 ).
3)Slide the " O2/DO selector " ( 4-11, Fig. 1 ) to the " O2 "
position.
Push the " Zero button " ( 4-9, Fig. 1 ) and the display
will show zero value.
4)Connect the " Oxygen probe plug " ( 4-21, Fig. 1 ) with
the " Probe input socket " ( 4-15, Fig. 1 ). Wait for
approx. 5 minutes at least until the display reading
values become stable & no fluctuation. Push the " O2
Cal. button " ( 4-12, Fig. 1 ) and the display will show
the values exactly same as 20.9 or 20.8. (As the
oxygen in air is 20.9 % typically, so use the
environment air 02 value for quick & precise
calibration).
Calibartion Consideration :
Please process calibration procedures under
wide and ventilating environment for best effect.
