ANALOG OUTPUT
CALIBRATION
This function calibrates the Analog Output by comparing the actual output
current with the nominal 4 mA and 20 mA currents. Calibration is done at the
factory and normally the transmitter does not need to be recalibrated.
The Analog Output Calibration function is available via the
HART command [2, 7, 1].
In RRM, this function is available via
Setup > Output
.
To calibrate the Analog Output current:
1. Start RRM and make sure that the transmitter communicates with the PC.
2. Click the
Output
icon in the
Device Config/Setup
toolbar.
3. Select the
Analog Out
tab in the
Output
window.
4. Click the
Calibrate DAC
button.
5. Follow the instructions to calibrate the 4 mA and the 20 mA outputs.
LOGGING
MEASUREMENT DATA
By using the Log Device Registers function in the RRM software, Input and
Holding registers are logged over time. It is possible to choose from different
pre-defined sets of registers. This function is useful for verifying that the
transmitter is working properly.
To log device registers, choose the
Tools > Log Device Registers
option to
open the
Log Registers
