_____________________________
In this panel you can choose the unit with which the device will measure
the temperature (
Default temperature unit °C/°F
). With some devices
the pressure unit can be chosen, too (
Default atmospheric pressure
unit
). When the device does not measure the atmospheric pressure,
but when it is necessary to know its value to measure some quantities
(calculated humidity and CO
2
), the atmospheric pressure value must
be entered (
Default value of atmospheric pressure in the area
according to altitude
).
With barometers, the correction constant can be entered here
for conversion to the equivalent sea level pressure. This constant can
be entered either as a current pressure converted to the sea level found
out e.g. at a near observatory, or through the medium of the elevation
above sea level.
General - Data and Time
___________________________
Here you can set the date and time running inside the device (
Date and
Time
). In the datalogger local current time is running according to your
setting. By means of the
UTC Offset
choice you can fix its relation
to the UTC.
This information will be available for all time data
provided by the device.
The device cannot automatically pass over
between summer and winter time.
CAUTION
- after changing date and time the data
recorded by the device will be deleted!
Advanced - LCD Display
___________________________
In this panel you can set a variety of display and keypad behaviour
modes.

_
In this panel you can set some functions of the
datalogger’s buttons,
a delayed switching-on of the datalogger or the control of its switching-
on by a binary input (according to type). In addition, the datalogger‘s
switching-on and/or off by a button on the datalogger panel can be
enabled or disabled.
In the standard mode the datalogger measures all channels using
an interval of 10 s. This interval can be shortened to 1 s when a faster
measuring procedure is required. A disadvantage of this mode is
a higher power consumption. When the device is operated for a long
time, there is no need for a fast response to the change
