Best measurement performance is achieved when the entire probe is located inside the environment to be monitored. This is the case, for example, when the EE872 is fixed onto a wall with the mounting clip HA010227 (not included in the scope of supply, see data sheet “Accessories”), or freely hangs from the ceiling on the connection cable. -
Page 8: Setup And Adjustment
Setup and Adjustment The EE872 is ready to use and does not require any configuration by the user. The factory setup of EE872 corresponds to the type number ordered. Please see chapter 3.1 for a model overview and the data sheet at www.epluse.com/EE872. The user can change the factory setup by using the Modbus configuration adapter (order code HA011018) and the PCS10 Product Configuration Software. -
