3.7 Recalling measured data
The display for stored data is activated by pressing the UP or DOWN key and
confirmed by displaying the letter “M” in the memory display. The measured
data stored are shown with their memory location. By pressing the UP and
DOWN keys once again, the memory is scrolled forwards and backwards. The measuring
process can be continued by pressing the ON key.
3.8 Clear memory
The memory can be cleared by pressing the ON key first and, keeping it
pressed, activating the UP and DOWN keys simultaneously; this also formats
the memory.
3.9 “Freezing” measured data in display
Pressing the HOLD key stores the currently displayed data. At the same
time, the letter “M” appears in the memory display. As long as the “M” re-
mains visible, the stored measured values are displayed. Press the ON key
to continue the measuring process.
3.10 Replacing batteries/rechargeable batteries
The batteries must be replaced when the battery display flashes. When replacing the batter-
ies the measured data stored in the internal memory as well as any existing reference values
are deleted! The batteries should be replaced when the device is switched off. There are two
different types of battery housings:
• Small housing
Open the battery compartment by pushing the two battery
compartment covers slightly upwards and removing them
sideways. Take out the two batteries from each side, replace
them and close the battery compartment.
• Large housing
The battery compartment cover can be removed by undoing
the retaining screw. Fold the cover of the battery compartment
upwards. Replace the four batteries, fold the battery compart-
ment cover down again and close by tightening the screw.
