Measurement with battery (Battery monitoring)
The battery symbol in the top right corner displays the current battery charge condition.
Approximately 15 minutes (depending on the analyzer configuration) before the battery is drained, the battery symbol
will start to blink red (about once per second).
When the battery is almost drained and the analyzer is not connected to the battery charger within
one minute, then the analyzer will switch off automatically to prevent deep discharge of the battery.
11.5
Operation temperature
If the analyzer has been stored at low temperatures, it will require some time to equilibrate to the ambient temperature
before being switched on. If it does not equilibrate, condensation will occur inside the analyzer!
If the temperature is out of its operation range (see chap. 15), you will see the following messages on the display.
or
Once one of these messages appears you will not be able to use the analyzer, it will give an acoustic signal until it has
reached the specified operation temperature b5°C and +45°C.
11.6
Condensate separator
The condensate separator must be checked before and after each measurement!
Please check if the condensate separator must be emptied and if the pleated filter is still white.
White = good for measurement dark = replace
