7 Memory Functions
In addition to a display memory, the MAVOMASTER is also equipped with an 8 GB measured value
memory. This makes it possible to record several measurements on site, and to read them out and
evaluate them at a later point in time. Stored values are retained when the instrument is switched off,
as well as when the batteries are replaced.
7.1 HOLD
– Freeze Display
The HOLD function freezes values at the display and facilitates delayed meter reading.
The HOLD function is activated by pressing the
HOLD key and HOLD appears at the display. After
pressing the HOLD key once again, the MAVOMASTER is returned to the continuous measuring
function. Display backlighting is controlled according to the selected LCD illumination mode.

7.2 MEM
– Saving Measured Values
During normal measuring operation, the momentary measured value is saved as a file in CSV format
to a daily folder (yyyy-mm-dd) by briefly pressing the
MEM key
– depending on the corresponding
setting as either Realtime_xxxx.csv or Realtime_hh-mm-ss.csv . T
he measured value’s number (xxxx)
is incremented for each storage operation, and current time is used for the time setting. A window with
the message “saved” appears as confirmation and an acoustic signal is generated.
If the
REL measurement function has been activated, Relative_xxxx.csv or Relative_hh-mm-ss.csv is
used as the filename and the reference value is written to the file as well.
