Test configuration
Before running a test, many input sensors must be scaled. Define sensor scaling parameters directly in the Sensor Scaling grid in the Test Configuration section.
To configure a channel for sensor scaling, first set the Sensor scaling mode in the gridscreenshot)
Depending on the mode selected, different scaling parameters must be specified to define the scaling line.
Sensor scaling mode | Scaling parameters |
---|---|
Defined slope intercept | Slope Intercept |
Defined zero span | Electrical zero Electrical span Physical span |
Defined two point | Electrical 1 Physical 1 Electrical 2 Physical 2 |
Experimental two point | See Experimental two point scaling |
Internal shunt resistor | See Internal shunt resistor scaling |
Strain gage | Strain gage factor Bridge factor |
It is possible to copy the properties from one input channel and paste them into another channel of the same type. To do this, select the channel to be copied and click Copy. Select the parameter to be copied and click OK.
To paste the copied parameters into a different channel, select the target channel and click Paste.
Zeroing a channel adds an offset, making the channel value as close as possible to the user defined zero target. The default zero target is 0.
Select one or more channels and click Zero.
NOTE
The Prerun zero mode must be set to Interactive only for a channel to be zeroed. By default, normally applicable channels such as bridges and encoders are set to this mode. Other channel types must be set manually if zeroing is required.
Click ZERO to measure the current channel data value, and adjust the cumulative zero offset which is stored in the Prerun zero offset channel parameter. Click RESET to clear any previous zero offsets. After zeroing is complete, be sure to save the test setup.
NOTE
It is recommended to select the Use system defined sensor scaling filters option in the System preferences to minimize the effects of noise on the accuracy of scaling measurements.
To view a digital display of the current channel values, select one or more channels and click Digital Meter.
Click Freeze to pause the reading
NOTE
Digital meters cannot be displayed while a test is running.
