The zero flow value for analogue output can be flexibly adjusted between the span of
4-20 mA using the menu item ‘0-Offset’.
This menu item works well for A-B function. The following table shows the function of
‘0-Offset’ with the input types available in the electronics:

10.9.1 Analogue output / Wiring type
While using analogue output, correct electrical wiring type must always be selected .
Otherwise the offset value of 4.0 mA will not be correct.
10.10 Service
10.10.1 Service / User service
A Reset function and Blanking function for selected menu parameters are available for
user in Service menu. Together with the activation of a user password, certain device
functions and parameters for the user can be locked by a master user.
10.10.2 Service / User service / Change password
The default administrator user password is set to "00000", the user functions are thus
freely accessible. If the user's password has been changed from "00000", password
request will be generated on next entry to User menu.
If the default password has been forgotten or misplaced, the master password can be
requested from KOBOLD.
10.10.3 Service / User service / Factory defaults
By activating this function, the user can reset the device to factory settings. All user
settings will be lost and the device is now reset to the factory settings.
