Heartbeat and Display Update Rate:
The flashing heartbeat
♥
icon is updated each time the
display
is updated (whether the CO
2
or other
values change or not). Normally the display is updated every 1 second. However, in extended mode the
display
is updated every 5 seconds (even though data is still being output and recorded every 1 second).
The extended mode saves power and prevents display ghosting. Extended mode begins approximately
30 seconds after the last keypress is made on any measurement screen. Return to normal 1 second
update rate will occur when:
•
Any screen button is pressed
•
The heartbeat icon is pressed
•
Any new CO2 reading is more than 10% changed from the previous CO2 reading.
Data Entry Screen
The Data Entry Screen is used to enter new numerical values. The screen is displayed whenever a new
value is required.
1. The name of the parameter.
2. The units associated with the parameter.
3. The acceptable range of values.
4. The value being entered.
5. The OK button selects the entered value. If the entered value is out of range, it is set to the
minimum or maximum value. It then returns to the previous screen.
6. The Cancel button returns to previous screen without changing the initial value.
