print a complete set of data and the "LOG"
symbol will appear on the bottom left hand
side of the display.
If no key is pressed, the display goes blank
after about 5 minutes. During printing, the display shows the time,
interval and the “LOG” symbol.

To reactivate the display press the RANGE key.

The printout provides the following information:

a - Date (DD-MM-YY)
b - A running log number
c - A running sample number (in that particular log)
d - Printing interval indicator in minutes
e - Time (HH-MM)
f - pH value
g - Temperature value

It is always possible to switch from the logging with printing function
to the logging function. Press the ALT and the PAPER keys at the
same time and the "LOG" symbol will start to blink to indicate that
the data is now stored only into memory.

Notes:

It is recommended to use the adapter during logging in
printing mode, especially when many printouts are going to
be taken.

Before proceeding with logging with printing, make sure there
is enough paper for your measurements. When the paper is
finished the meter will not advise the operator and the
printouts could be lost. If this happens, data will continue to
be stored in memory, and it is always possible to print the
