Inspection DPM High 19
Measurement
6 Measurement
The gage model MMS Inspection DPM is for continuously measuring tempera-
ture and humidity to determine the dew point and the difference between sur-
face temperature and dew point. You can log all these climate factors over a
prolonged period and emit an optical warning if specification limits are ex-
ceeded.
The following factors are measured: air temperature (Ta), relative humidity
(%RH) and surface temperature (Ts)
From the measured factors, the dew point (Td) and the difference between sur-
face temperature and dew point (Ts-Td) are calculated.
All measured and calculated climate factors are saved simultaneously (manu-
ally or continuously).
Notes on measuring
Measurement errors
Measurement errors occur if ambient air
cannot flow through the housing grille in the
lower area of the gage!
►
Keep the housing grille in the lower area of the
gage clear. Avoid covering with hands, mate-
rial or other objects.
►
Allow ambient air to flow unhindered through
the housing grille in the lower area of the
gage.
►
Observe the instructions for handling the gage
during a measurement, described in Chapter
"Correctly holding the gage during the
measurement" on page 21
Measured readings outside the specification
limits are displayed in red and indicated by an
illuminated red LED.
The gage vibrates during measurement acquisition if this is activated in the
gage settings.
The probes for air tempera-
ture und relative humidity
are protected by the hous-
ing grille
