7.2 Current simulation
A signal current independent of the acting
system pressure can be simulated if the
function or specific responses of any
evaluating instruments connected in the
system are to be checked.
The current value is settable within the
limits of 3.6 mA and 22 mA using the "Set
Simulation Current" parameter (V7H2).
7.3 Reset
By entering a code, the entries in the matrix
are reset partially or completely to factory
settings.
The Cerabar S differentiates among different types of reset each with various responses.
To find out which parameters are reset with the 5140, 2380 and 731 reset codes, refer
to the table on page 45.
Other reset codes have the following effects:
•
Device warm start = 62
•
2509: This reset sets the lower and upper sensor calibration limits and the zero
correction value to the factory setting. I.e.:
Low Sensor Trim = Low Sensor Limit (V7H4 = V7H6),
High Sensor Trim = High Sensor Limit (V7H5 = V7H7).
Zero Correction Value (V9H6) = 0.0
