Page 22: Calibrating A Pressure-To-Current Transmitter
7.2 Calibrating a Pressure-to-Current Transmitter To calibrate a pressure-to-current transmitter (P/I), perform the following steps: 1. Connect the calibrator and the pump to the transmitter. 2. Apply pressure with the pump. 3. Measure the current output of the transmitter. 4. Ensure the reading is correct. If not, adjust the transmitter as necessary. - Page 23 Example: Suppose a pressure transmitter under test is 30 psi (2 Bar) Full Scale and outputs a corresponding 4 to 20 mA signal. The user can program in a 0 to 30 psi pressure span into the calibrator and the calibrator will calculate and display the deviation or % Error from the expected 4 to 20 mA output.
- Page 24 4. LOOP POWER can be toggled on/off, select NEXT when done. 5. Use SELECT to toggle through the UNIT options, and select NEXT to move on. 6. Use the pressure range, select DONE SET when finished. 7. Again, use the arrows to set 0% point and select DONE SET when finished and the %ERROR mode will be ready to use.

Note: The 0% and 100% point will be saved in non-volatile memory until they are changed again by the user for the internal sensors, and external pressure modules. When using an external module the 0% and 100% are set to low and full scale of the module until the user changes it, or if it was previously saved. - Page 26 Setup 3: The upper display is set to [P1] mode and the middle is set to [VOLTS] mode, lower is off. Setup 4: The upper display is set to [P1], the lower display is set to [EXT]. Setup 5: The upper display is set to [P1], and the lower display is set to mA Loop.
