Maintenance and service
Change battery
If the unit does not display the time after it has been switched off and on again, the internal backup
battery must be replaced. The battery used at the factory has a service life of several years. The
clock is powered by the mains adapter when it is switched on. Therefore, the battery life is longer if
the unit is not switched off.
Proceed as follows:
•
Switch off the unit and disconnect the power supply.
•
Open the control unit housing with the 4 screws. On the inside you will see the battery
holder.
•
Replace the battery with a new one of type CR2032.
•
Close the control unit again. Make sure that the connection cable between the display board
and the control unit has not come loose.
•
Dispose of the battery at a collection point for batteries.
Software update
The analyser offers the possibility of a software update. As part of the product improvement, you
will receive software updates via your dealer or via our website. Should this be necessary, your
dealer will send you a file with the name TP28xxx.bin.
To perform a software update, proceed as follows:
•
Switch off the unit and disconnect the power supply.
•
Open the control unit housing with the 4 screws and remove the SD card.
•
Copy the file TP28xxx.bin to the SD card with the help of a computer and insert it again.
•
Close the control unit again. Make sure that the connecting cable between the display board
and the control unit has not come loose.
•
Press and hold the [OK] key and switch on the unit. As soon as Software Update appears in
the display, release the [OK] key. The machine updates the software.
•
Switch off the unit, remove the SD card and delete the file TP28xxx.bin from the SD card.
•
Insert the SD card back into the unit.
•
Check the unit configuration of the unit.
