52 Calibrate Analog inputs and outputs
Section 5: Calibrate and configure the meter 3410 Series Gas Ultrasonic Meters Operations Manual
January 2018 3-9000-777 Rev E
5.3 Calibrate Analog inputs and outputs
An analog input can be calibrated regardless of the corresponding input type, pressure of
temperature. However, if the corresponding input type is selected as Live, then the input being
calibrated is considered to be invalid and the in-use value depends upon the
FlowPOrTSrcUponAlarm selection (see above). In this case, the appropriate data point
(
FlowPressureWhileCal, FlowTemperatureWhileCal) is set to the in-use value so that it can be
logged in the optional log.
The offset and gain can be reset to the default values (0 and 1, respectively) by clicking the
Reset Defaults button.
Click the
Edit Scaling button to modify the input scaling.
From Daniel MeterLink, select
Calibrate to make changes using the Analog Inputs Wizard.
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.
The Offset method requires a single calibration point and only affects the input’s
calibration offset parameter.
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. The screen(s) displays the current (live) reading. When the input is stable, click the
Hold
button to freeze the current reading.
The WRITE PROT. switch on the CPU Module must be disabled or the calibration values will not be
updated for a meter.
Clicking the Reset Defaults button writes the offset and gain immediately - the previous values cannot
be restored.
Changes made to an analog input’s offset, gain, and scaling values are written to the log.
