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 data at a later time through
setup code 00.
• It is possible to insert a new paper roll during logging session.
• Once in the logging mode, the interval cannot be changed. Exit
the logging mode first (pressing the ALT and LOG keys) to set a
new interval.
• If the LOG key is pressed while in logging with printing mode, a
printout is produced without affecting the running sample number
and the value is stored in Log on demand area.

to enable the printer while in low battery
condition the message "bAtt" will appear for
a few seconds on the LCD.
Note: When an external adapter or new batteries are connected, the
printing must be manually enabled in order to return to logging
