Technical data

NOTICE
Changes made to an analog input’s offset, gain, and scaling values are written to the log.
The maximum length of time that the analog output can remain in the test mode is
specified via the NonNormalModeTimeout data point. Note that this data point applies to
other tests as well. The NonNormalModeTimeout data point can be changed using the
Daniel MeterLink Edit/Compare Configuration screen. It can be set within the range [1, 30 min]
and has a default value of 2min.
Analog inputs calibration
1.
Choose the analog input to calibrate, either temperature or pressure and click Next.
The Current|Calibration screen shows the current offset and gain and the input scaling
(i.e., the pressures or temperatures corresponding to the minimum (4 mA) input
and maximum (20 mA) inputs).
2. Click Next to proceed to the Calibration|Method screen then, select either the offset
or two-point calibration methods.
a. The Offset method requires a single calibration point and only affects the input’s
calibration offset parameter.
b. The two-point calibration requires calibrating at two different points (ideally far
apart in value) and affects the input’s calibration offset and gain parameters.
Depending upon the selected calibration method, either one or two screens will
follow when the Next button is clicked.
3. Daniel MeterLink displays the current (live) reading. When the input is stable, click
the Hold button to freeze the current reading.
