3.4.3 Error Codes and Messages
The MMR101 has a series of error codes and messages that appear on the display to indicate certain conditions.
Note: Fields that display data cannot be modified. Fields that can be modified have a flashing digit.

3.4.4 Measurement Accuracy
The sensor measures relative humidity and temperature. Other moisture units are derived from these live
measurements.
The accuracy of the instrument is specified as a percentage of relative humidity. Inaccuracy is a result of the
temperature dependence of relative humidity. This dependence is due to physical properties and is independent of
the measuring apparatus. The influence of temperature fluctuation should be taken into account for relative
humidity, as well as the derived moisture units.

Matrix Description of Function
" - - - - " If this appears in the matrix field, it indicates that the
matrix position is assigned.
V9 H0 Displays the current error code. If no error code is
active, dashes ("- - - ") are displayed in this matrix
position. If several errors exist, the error codes are
displayed using the following priority:
Error Code Error Status
401 Moisture sensor error
201 Relative humidity outside upper
measuring range
202 Relative humidity outside lower
measuring range
203 Temperature outside upper
measuring range
204 Temperature outside lower

205 RH loop span too large
206 RH loop span too small
207 Temperature loop span too large
208 Temperature loop span too small
