K-CAL: viewing live data on the oscilloscope
Check what a K-Series module measures before you deploy it. Show any channel's value, plot channels on the K-CAL oscilloscope and save the trace.
Open the Measurement tab
Connect K-CAL to the module, then open the Measurement tab. For the connection, see K-CAL: installing the software and CAN interface drivers.
The top of the tab shows one channel's value. The bottom holds the item list and the oscilloscope.

Show a channel's value
Select the radio button of the channel you want. K-CAL shows its measured value. On a K-BOX, if a conversion table or formula is assigned to the channel, K-CAL also shows the converted value with its units and the formula or table name. Conversion tables and formulas are K-BOX features. See K-BOX: conversion tables and formulas.

Add channels to the oscilloscope
There are three ways to put channels on the oscilloscope:
- One channel. Select the channel's radio button, then select Scope Add on the toolbar.
- All channels from the toolbar. Open the Scope Add menu and select Add all.
- All channels from the item list. Right-click in the Item information area and select Add all.
Each channel you add appears in the Item information list with its colour, name, units and current value.

| Del all | Removes every item from the oscilloscope |
| Group and scale to | Sets a custom scale for the selected items |
| Reset scaling | Restores the default scaling |
| Not Use | Removes conversion tables or formulas from the selected items (K-BOX) |
Oscilloscope toolbar
The toolbar above the oscilloscope controls the plot. Its buttons are icons. The table lists their functions in order, from the left.
| Function | What it does |
|---|---|
| Online | Puts the oscilloscope online |
| Clear | Clears the data logged in the oscilloscope |
| Save | Saves the logged data in one of the formats listed after the table |
| Open | Opens previously saved data |
| Step mode | Shows steps between data points |
| Separate | Draws each item in its own band |
| Axis mode | Changes the axis display mode |
| Show points | Marks each data point |
| Cursors | Shows measurement cursors |
| Reset zoom | Resets the zoom factor |
| Reset X zoom | Resets the X-axis zoom factor |
| Zoom in X / Zoom out X | Zooms the time axis in or out |
| Fit | Fits the items to the visible zoom area |
| Zoom in Y / Zoom out Y | Zooms the value axis in or out |
| Zoom in all / Zoom out all | Zooms both axes in or out |
K-CAL saves oscilloscope data in these formats:
- Vector MDF (
.DAT) - MATLAB 5.0 (
.MAT) - MATLAB 5.0 structured, single or double precision (
.MAT) - MATLAB 5.0 structure extended (
.MAT) - Comma-separated values (
.CSV)
Oscilloscope menu
Right-click the oscilloscope for more options:
- Separate
- Step mode
- Axis mode
- Show points
- Cursors
- Scale
- Axis color
- Clear
- Export to image file
- Copy to clipboard
Scale fixes the time axis at a span from 1 second to 10 minutes, or returns it to normal.
