8. Inserting and Replacing Batteries
• Open the battery compartment (figure 1, item 5) on the bot-
tom by first turning the screw (figure 1, item 7) of the battery
compartment lid out and taking off the battery compartment lid
(figure 1, item 6).
• Insert two type AAA/micro batteries with correct polarity into the
battery compartment (observe plus/+ and minus/-), see notes in
the battery compartment.
• Attach the battery casing lid and screw it back on. The thermo
logger is now ready for operation.
• The batteries require changing when the display contrast is very
weak or the device can no longer be switched on.
9. Operation
a) Switching On/Off
When you want to measure temperature, keep the “On/Off” button
(figure 1, item 1) pushed for approx. two seconds. The thermo log-
ger will switch itself on.
To deactivate the thermo logger, keep the on-off button pushed
again for approx. two seconds until the display goes out. Then
fold the penetration sensor back by 180° into the corresponding
housing opening (clean the penetration sensor first, see chapter
“Maintenance and cleaning”).
