User Manual EE260 Heated Humidity and Temperature Probe for Meteorological Applications
5 Setup and Adjustment
The EE260 is ready to use and does not require any configuration by the user. The factory setup of
EE260 corresponds to the type number ordered. Please refer to the data sheet at
. The user can change the factory setup with the help the EE-PCS Product Configuration Software,
the Modbus configuration adapter (order code HA011018) and the EE260 configuration cable (order
code HA011020).
Besides the measurand selection of the analogue and digital outputs and their scaling, the digital
interface settings may be changed. The RH and T measurement is offset and 2-point adjustable. It is
possible to enable or disable the sensing element and the probe heating (separated from each other;
factory setting for both: enabled) and the NAMUR error indication (factory setting: disabled). For the
purpose of pressure compensation, the barometric air pressure at the operating site may be set.
Please note:
The EE260 may not be connected to any additional power supply when using the Modbus
configuration adapter HA011018.
