Protimeter MMS Moisture Measurement System Page 9
Note: The Mixing Ratio (AbS) or Specific Humidity (g.Lb) displays are
preceded by a momentary beep to draw attention to the unit of
measure prior to displaying the value.
%rh and T
AIR measurements are
made with the Hygrostick or
Humistick sensor, and the MMS
instrument uses these values to
calculate T
DEW. When using the
MMS to measure the conditions in
air, the humidity probe is normally
connected directly to the instrument.
However, when it is impractical or
awkward to use the instrument in this
way, the extension lead may be used
to connect the Hygrostick or
Humistick to the instrument.
Typically, the extension lead will be
used when taking readings from
probes that have been embedded in
structures such as walls and floors.
2.4 Condensator Mode - Selection and Use
The Condensator Mode enables the
user to assess the risk of
condensation occurring on surfaces
or to confirm whether or not
condensation is present on a surface.
To use the MMS as a Condensator,
connect a Hygrostick probe directly
into socket EC1 and connect the
surface temperature sensor into
socket EC2. Turn the MMS ON by
pressing . Select the condensator
mode by pressing
XX repeatedly
until the word CONDENSATOR is
visible at the top of the LCD. Then
press
X to select relative humidity (%rh), ambient temperature (TAIR), dew
point temperature (T
DEW), surface temperature (TS) or temperature difference
(T
DIFF) as required. TS and TDIFF measurements can only be obtained if a
