| + | * This is likely occurring because you are using shift or scan mode at a low sample rate. The two calculations in question are based the values between the time cursors. Unlike Repeated mode, where the whole buffer of data is collected before being rendered and then calculated upon, Scan and Shift modes fill up their data over time, resulting in a situation where WaveForms is trying to calculate on data that hasn't come in yet. Once the Scope Plot is filled with data, simply right click on the Measurement line item with the Syntax Error, choose Edit, then click okay without changing anything at all to resolve the issue. | ||

| + | * Check to see if the Scope instrument started running. | ||
| + | * Confirm that your load is ready to receive power and isn't switched off. | ||
| + | * If you adjusted the timebase to be much wider, change the Scope mode from Repeated to Scan or Shift so that WaveForms isn't collecting all 5 or 10 seconds worth of data before displaying it on the screen. | ||
