Via Local Adjustment
In order to enter the local adjustment mode; place the magnetic tool in office “Z” until flag “MD” lights
up in the display. Remove the magnetic tool from “Z” and place it in orifice “S”. Remove and reinsert
the magnetic tool in “S” until the message “LOC ADJ” is displayed. The message will be displayed
during approximately 5 seconds after the user removes the magnetic tool from “S”. Let’s take the
upper value as an example:
Let’s take the upper value as an example:
Apply to the input a position of 100.0%
Wait until the current of readout of parameter P_VAL (PRIMARY_VALUE) stabilizes and then
actuates parameter UPPER until it reads 100.0%.
Let’s take the lower value as an example:
Apply to the input a position of 0.0%.
Wait until the current of readout of parameter P_VAL (PRIMARY_VALUE) stabilizes and then
actuates parameter LOWER until it reads 0.0%
Limit Conditions for Calibration
Upper:
-10.0%<= CAL_POINT_HI <= 110.0%
CAL_POINT_HI#CAL_POINT_LO
CAL_MIN_SPAN = 1.0%.
Otherwise, Invalid calibration request.
Lower:
-10.0%<= CAL_POINT_HI <= 110.0%
CAL_POINT_HI#CAL_POINT_LO
CAL_MIN_SPAN = 1.0%.
Otherwise, invalid calibration request.
If all limit conditions are according to these rules, we will get successful in the performed operation.
NOTE
Trim mode exit via local adjustment occurs automatically should the magnetic tool not be used during some
seconds. Keep in that even when parameters LOWER or UPPER already present the desired value, they
must be actuated so that calibration is performed.
NOTE
16: Default Value Set
22: Out of Range
26: Invalid Calibration Request
Temperature Trim
Write in parameter CAL_TEMPERATURE any value in the range -40°C to +85°C. After that, check
the calibration performance using parameter TEMPERATURE. The user can select the unit using
the parameter TEMPERATURE_UNIT. Normally, its operation is done by a method in the factory.
