symbol on display will start to blink.
After approximately 5 minutes the display will switch itself off but the
logging function remains active.
To reactivate the display press the TIME key.
Notes:
• Once in the logging mode, the interval cannot be changed. Exit
the logging mode first (press ALT and LOG together) and then set
the new interval.
• If the PRINT key is pressed while in logging
mode, a printout is produced without affect-
ing the running sample number.
SAMPLE NUMBER
During logging it is possible to know the running sample number.
Press the LOG key twice and the display will show the running
number in the current log together with sample number symbol "Sn".
LOGGING MODE WITH PRINTING
This function is useful in a variety of applications from unsupervised
monitoring to satisfying regulatory requirements. In addition to the
printouts, the measurements are also stored into the memory.

To print the values shown on the display, press
PRINT.
This function can be activated in normal operation mode as well as
during logging (and scanning) modes.
When in the measurement mode, each printout provides the following
information:
a – Running sample number
b – Date (DD-MM-YY)
c – Time (HH.MM)
d – RH% value
e – Temperature value
LOGGING MODE WITHOUT PRINTING
This function is particularly useful when measurements have to be
taken continuously even in the absence of an operator over a long
period of time. In this mode data will be stored directly into memory.
Set the appropriate logging interval (see pages 14-16).
Press the ALT and LOG keys simultaneously to enter the logging
mode. The current log number and remaining page numbers will
appear for a few seconds on the display to indicate the correct
operational mode. The printer will print a complete set of data and
the "LOG" symbol will appear on the secondary LCD.
