AVG Variable
Push AVG button. 5.
Push INC button (increase) or DEC button (decrease) until the display 6.
matches the desired value.
Push SAVE button to store new AVG variable. 7.
To Exit AVG / BLANK Mode
Push DONE button twice slowly to get back into normal operation mode. 8.
The Blanking variable is programmed in the same manner, except for step 5 above
in which you would push the BLANK button.
4.3 Sample Mode
The Sample Mode feature allows the user to take a measurement using a predefined
repeatable method to eliminate user “interpretation” of a gas concentration that is
changing. This is similar to a digital scale, for example, so the exact same reading
will be taken regardless of who is taking it.
The measuring sequence used in Sample Mode is as follows:
Draw a •
Sample
for a user programmed sampling time to allow unit to
stabilize to the existing gas concentration.
Measure •
the gas concentration and average it for a user programmed
measuring time.
Clear • the gas concentration to below a user programmed recovery value
before allowing another cycle to start. (Unit should be moved to fresh air
during the clear time.)
Taking a sample
To take a sample, locate the detector at the desired sample location, and push the
SMPL (sample) button on the normal operation screen. The unit will count down
the Sample time, followed by the Measure time, at the end of which the average
value will be displayed.
Note
the displayed sample value. Pushing the CLEAR button will return the unit to
the normal operation screen once the gas concentration is below the predefined
recovery value. The unit is now ready to take another sample if desired.
Programming sample mode variables
The sample mode variables are Sample, Measure and Clear as described above.
The following procedure will change the Sample variable.
To Enter SAMP / MEAS / CLEAR Mode
Push power button to turn unit on. Wait for power up sequence to finish 1.
(30 seconds).
Push and hold the unnamed button (second from left) first, then Push
2.
and hold the Menu button. Hold both buttons until the screen goes blank
(two seconds). Release both buttons and the unit is now in Programming
Mode.
