The pH meter uses various messages to selectively inform you about

possible errors or operating problems. These are shown in the bottom

line of the display and illustrated by a symbol in front:

Type Symbol Example of a message

Error same buffer

Warning

calibration data out of limits

Information

manual stop

drifting measured value

change buffer

calibration OK

infrared connection OK

(symbol only, no message)

battery low

Monitoring

calibration interval expired

These messages can normally be removed by pressing the <QUIT>

key. However, some messages will remain until their cause has been

remedied. For example, this applies to the mode T if no temperature

sensor is connected.

Attention!

Please note that you should not press <QUIT> to acknowledge a

message while a report is being produced as this will cancel the re-

port.

The following table lists alphabetically all the messages which could

appear on the display of the pH meter.
