Description
Select Source
Selects the measurement that shows on the selected analog output. Only the
measurements that are recorded in the data log can be selected.
Select Loop Scale
Sets the analog range for the analog output. Options: 0–20 mA or 4–20 mA
Select Loop
Sets the loop power source to be internal or external.
Power
Internal—Selects the sampler as the power source of the analog output. External—Selects
another device as the power source of the analog output. When external is selected, the
sampler acts as a variable current limit device.
Set Transfer Value Sets the analog loop value that is supplied on the analog output when an input
measurement error occurs. Options: 3.0 to 25.0 mA
An input measurement errors occurs when:
• A sensor malfunction occurs.
• The input measurement value from the sensor is not valid.
• The sensor is not detected by the controller.
• The sensor has been removed by the user.
Calibration
Calibrate the analog signals
Calibrate the analog inputs to make sure that the analog input signals (4 mA and 20 mA) that are
supplied by external instruments are correctly measured by the sampler. Calibrate the analog outputs
to make sure that the analog outputs (4 mA and 20 mA) that are supplied by the sampler are the
correct values.
Item to collect: Digital multimeter that supplies an analog signal
1. Push CALIBRATE.
2. Select I/O Module>Analog Input (or Analog Output).
3. Select the analog input (or analog output) to calibrate.
4. Obey the prompts on the screen. Connect the multimeter to the applicable analog input or analog
output terminals.
