Single channel zero
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
In the single channel editor, the Mode in Input channel zero parameters must be set to Interactive only or Normal Test Starts 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 offset in Input channel zero parameters. Click CLEAR ZERO 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.
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.
