Scaled D/A Trim
For the Scaled D/A Trim, the user can adjust the transmitter digital-to-analog
converter on an alternate unit of measure, such as voltage (example: using a
voltmeter across a 500 ohm resistor produces a low point of 2 volts a high
point of 10V).
1. Right-click on the transmitter icon.
2. Highlight “Calibrate” from the pop-up menu.
3. Click “Scaled D/A Trim.”
4. If you expect your measurement to be from 4 – 20 (mA, V, etc.), click
“Proceed.” Otherwise, click “Change.”
5. Enter the expected low set point, and click “Next.”
6. Enter the expected high set point, and click “Next.”
7. Follow steps 5-7 on the above D/A Trim procedure, using the low and
high values you entered as reference points instead of the normal
4mA and 20mA.
To restore the D/A Conversion to the factory default settings:
1. Right-click on the transmitter icon.
2. Highlight “Calibrate” from the pop-up menu.
3. Highlight “Sensor Trim” from the submenu.
4. Click “Factory Trim.”
5. Select “Yes,” and click “Next” when asked if you want to set the DAC
(Digital-to-Analog Converter) Trim to factory defaults.
6. Click “Finish.”
Reset
The reset command reinitializes the transmitter microprocessor. This is the
equivalent of cycling power to the 3095.
NOTE
This procedure does not return the transmitter to factory trim settings.
1. Right-click on the transmitter icon.
2. Click “Reset” from the pop-up menu.
3. Read the warning message and click “Next.”
4. The transmitter will reset automatically. Click “Finish” to close the
window.
