Single channel two point scaling

Use the experimental two point scaling option to define the two point parameters based on experimental measurements.

When this task starts, the GUI displays some temporary parameter settings in the grid interface. These can be ignored as the user defined settings are restored later. The Units, Physical 1 and Physical 2 values can be modified before or after the Electrical 1 and Electrical 2 values are measured.

Click MEASURE 1 to take the first reading (electrical 1). Then click MEASURE 2 to take the second reading (electrical 2). Both measurements must be completed to set the channel electrical values. To restart the scaling process, close the panel and click Two Point Scaling again. After scaling 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.

Click the options menu button to access additional options:

  • Use scientific notation: Select scientific notation for extremely large or small values.
  • Decimals: Select the number of decimal places to show.
  • Update rate: Select the rate at which the display refreshes at 1, 2, 5 or 10 times per second. Note that in cases where the channel sample rate is less than the selected update rate, the display refreshes at the lower sample rate.
  • Control: Open the Shunt control dialog. This is not available for all channel types.

NOTE
For the meter to show accurate readings, the system starts a background test run for the duration of the digital display. No other digital displays or test runs can be started.

NOTE
MX modules output overflow values when no suitable connector is found. This is represented by a series of "+" characters on the display.
