TOP LINE
The top line of the display will read '% Water Vapour' after a COLD START.
The top line can be configured to also read -
Dew Point1
Absolute Humidity Kg/Kg 1
Mass Fraction g/Kg 1
Relative Humidity
Oxygen % 1
++ Note that these readings are of the zone 1 if 'Indirect, 2 Zone" is selected in set-up step 24.
This can be changed by selecting one of the above to be transmitted on channel 1 output, using set-up step 33.
Whichever parameter is chosen to be transmitted on channel 1 will also be displayed on the top line of the display.
The top line indicator (far right column) is also used to show running status of the analyser.
The symbols that will appear are –
'*' Flashes every 2 seconds, showing that the analyser is running normal calculations.
'Z' The analyser is calculating the impedance of the oxygen sensor(s)
'#' The analyser is doing an automatic calibration of the analog inputs
'+' The analyser is checking automatic timed events such as gas calibration and purge
BOTTOM LINE
The bottom line has selectable items available. See section 3.1 (below) and section 4.5, set-up step 40 (lower line
display set up).
3.1

DISPLAY BUTTON

The upper line on the display will read '% Water Vapour'
The following are available for display on the lower line:-
1. Dew Point Temperature
2. Dryer Absolute Humidity Kg/Kg / Mass Fraction g/Kg
The diplay of absolute humidity / mass fraction is selectable using the extended setup options
3. Relative Humidity %
4. Probe 1 Oxygen %, as read by the 1231 probe
5. Probe 2 Oxygen %, as read by the 1234 probe, RGS / External Dry Oxygen %
6. Probe 1 EMF (millivolts)
7. Probe 2 EMF (millivolts)
8. Probe 1 temperature
9. Probe 2 temperature / Dryer Thermocouple temperature
10. Probe 1 Impedance.
11. Probe 2 impedance
The probe impedance will show 'n/a', until the probe reaches 800°C, approximately 5 minutes from switch on.
12. Ambient Temperature (Inside the analyser)
13. Water Vapour 2 %* / Ambient relative humidity
14. Dew Point 2 / Dryer temperature
15. Dryer Absolute Humidity 2 Kg/Kg* / Mass Fraction 2 g/Kg* / Reference Gas Temperature
16. Run hours
* These options become available when the analyser is set to 2 zones, see section 1.1
