This video tutorial will teach the user how to configure the Digital MultiMeter (DMM) displays in the TermLAB application. The TermLAB DMMs are small digital readouts that are used to display the results of various measurements or calculations that are made by the TermLAB program. Each TermLAB channel supports 3 DMM presets and each preset can be configured to display as many as 5 DMM readouts. Each DMM readout can be configured to display the results from 105 different measurements or calculations.
Screen Shots


True power readings are displayed on the primary readout (orange). The current and voltage waveforms may displayed on the scope. User selectable power related measurements can be assigned to the smaller DMM readouts to the right of the primary display.

The TermLAB Power Probe adds more than 70 additional measurements to the TermLAB Magnum or Rebel. The user can assign these measurements to the various DMM readouts.

Each channel in TermLAB has three banks of DMM readouts. Each bank can display up to 5 DMM readouts. Each readout can be individually assigned by the user.
