6.2.3. Factory settings (M52)
This function resets the device settings
to factory settings.
Even when resetting the device to factory
settings or when there are no batteries
in the device, the measurement data re-
mains in the memory and is not deleted.
Information about deleting the measured
data is provided in chapter 9.2.
6.2.4. Acoustic function (M53)
Activating or deactivating the acoustic function switches the data logger's
acoustic signal either on or off. If the acoustic function is active, the function's
display symbol is shown on the display.
When the acoustic function is active, alarm results are indicated as a tone, pro-
vided an active alarm has been preset for one or more of the three display
measured values in the SmartGraph software.
If the acoustic function is not active, then none of the navigation steps which
require the mode selection button on the data logger to be pressed are acknowl-
edged by a tone. The same applies for selecting a mode. If no selection is
made, and thus the setting level is exited, then a tone is also emitted.

7. Measured values display and
data recording
7.1. Sensors, channel groups and
measuring channels
Model THI
The THI data logger has two internal sensors to detect measured values from a
total of six channel groups. These channel groups (measured values) are: Air
temperature in °C, air temperature in °F, dew point in °C, dew point in °F,
relative humidity in % and absolute humidity in g/m³.
For each channel group, there are four measuring channels for recording:
Current measured value (cur), minimum measured value (min), maximum meas-
ured value (max) and average measured value (mid). In total, there are 24 meas-
uring channels available for your THI data logger, as shown in table 1.
Model THIP
The THIP data logger has three internal sensors to detect measured values
from a total of eight channel groups. These channel groups (measured values)
are: Air temperature in °C, air temperature in °F, dew point in °C, dew point in
°F, relative humidity in %, absolute humidity in g/m³, relative air pressure in hPa
and absolute air pressure in hPa.
For each channel group, there are four measuring channels for recording:
Current measured value (cur), minimum measured value (min), maximum meas-
ured value (max) and average measured value (mid). In total, there are 32 meas-
uring channels available for your THIP data logger, as shown in table 1.

* When selecting a channel for display, the current measured value (cur) is always automatically shown.
** For more specific determination of measured values, entering the site height via the SmartGraph software is necessary.
