10.2.1 Configurable measuring ranges
Initially the ranges for the four measuring channels can be configured from a list of
eight ranges (* factory default settings).

The measuring range depends on the sensor type. (see data sheet)
The range, the units (2 characters), and a designation are programmed automatically;
this designation comprises the familiar abbreviations listed in tables issued by the
Deutscher Wetterdienst (German Meteorological Service) and the newer symbols de-
fined in VDI/VDE 3514.
10.3 Technical data
Operative range
The temperature depends on the sensor type.
Measuring ranges
Temperature -100 to +200 °C*
Accuracy ±0.2 K at 23 °C ±5 K
Humidity 0 to 100 % RH
Accuracy ±1.3 % RH at 23°C ±5 K
Atmospheric pressure 300 to 1100 mbar

at 23°C±5K
Calculated quantities see 8.2.1
Atm. pressure compensation
0 to 6500 mbar (programmable)
Refresh rate
1 second for all four channels
Connector colors
2 colors, light gray and dark gray, red lever
Standard baud rate
115.2 kbaud (freely selectable from 1200baud up to
921kbaud)

Sleep mode on the device
Possible (for extensions a 1s delay is necessary)
* Persistent use in the high-temperature range (>170 °C) may incur a loss in accuracy and / or
damage to the measuring cell.
