Operating Modes - TESTO 525 Mode D'emploi

The measurement values can be falsified by a change in the position of the measuring instrument.
After zeroing, the position of the measuring instrument must not be changed. Carry out zeroing befo-
re every measurement in order to compensate faulty positioning or long-term zero-point drift.
The modes in the table below can be selected in succession by pressing the MODE key.
After switching on the instrument is in the mode normal always.
