Output Check Procedures
The Output Check has the following procedures:
•
The Loop Test procedure checks for continuity and the condition of
components in the output current loop.
•
The Trim DAC Current procedure calibrates the output of the Digital-to-
Analog converter for minimum (0%) and maximum (100%) values of 4 mA
and 20 mA, respectively. This procedure is used for Transmitters operating
online in analog mode to ensure proper operation with associated circuit
components (for example, wiring, power supply and, control equipment).
•
Precision test equipment (an ammeter or a voltmeter in parallel with
precision resistor) is required for the Trim DAC Current procedure.
The Transmitter does not measure the given PV input or update the PV output while it
operates in the Output mode.
Constant Current Source Mode Procedure (Loop Test)
1. Establish communication with the Transmitter. For these procedures, the values of
components in the current loop are not critical if they support reliable communication
between the Transmitter and the PC Host/Handheld Configurator
2. On the Host visit Services Tab under Advanced Configuration menu.
3. Select the Loop Test button; the LOOP TEST box will be displayed.
