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.
