Protimeter MMS Moisture Measurement System
If this should occur, re-zero the instrument as follows:
1.
Remove any attached accessories
and select
Moisture Search Mode
(see section 2.1 for instructions).
MOISTURE & REL
is displayed.
2.
With one hand, hold the instrument
at least 12 in. (0.3 m) from all
objects (see the figure to the right).
3.
With your other hand,
simultaneously press the
XX
and
X
buttons. Hold them down until the
display shows
nul
, then
Air
. Quickly
release the buttons and continue to
hold the instrument as shown, well
clear of your body and your other
hand. Keep the instrument in free
air (i.e. at least 12 in. (0.3 m) from
all objects) while the display is
showing
Air
.
4.
After about 10 seconds, the display should return to normal and the
instrument should read zero when held in free air.
You may now take normal

readings with the MMS.
2.1.1.1 Troubleshooting the Zeroing Function - The instrument
changes mode when zeroing Is attempted
If the instrument changes mode when you attempt to zero it, you have most
likely not pressed the two buttons at exactly the same time. Return to
Search
Mode
and attempt to press and hold the two buttons simultaneously.
2.1.1.2 Troubleshooting the Zeroing Function - The instrument
shows
Air
, but then displays
Err
or
E30
and shuts
OFF
If this situation occurs, repeat the zeroing procedure. If this does not solve the
problem, it is likely that the temperature adjustment is outside the permitted
range. If possible, allow the unit to return to normal room temperature (about
20°C/68°F). If the unit will not re-zero at this temperature, the unit is likely
faulty and requires repair/service.
