2.5.3. HART® Transmitter Measurement Range Adjustment (CH Option)
While the instrument is being connected, the DESCRIPTION tab shows information about the identification
of the instrument, such as TAG, manufacturer, description, message, date, measurement range and input filter
(damping). Some of these parameters can be changed in the STANDARD SETUP.
On the DESCRIPTION tab, the MIN and MAX fields indicate the measurement range of the HART
transmitter. For PV (primary variable) equal to the MIN value, the transmitter should generate 4 mA. For PV (primary
variable) equal to the MAX value, the transmitter should generate 20 mA. The maximum allowable range of the
transmitter is shown above (RANGE...). To edit the working range of the transmitter, simply change the MAX and
MIN values and press the SAVE RANGE button
In this screen you can also edit the unit of the primary variable and the input filter (damping).
