Training

The training programme incorporated into the PDU software is designed to cover the needs of new users and those who have basic PDU skills but require further training on the DMM and Datalogger functions.

Select 'Training' from the PDU main menu to bring up the training menu.

New User Training

The new user training program takes the student through a structured sequence of activities to learn the meaning and use of the basic screen icons. The trainee may then work through programmed exercises to learn the digital multi-meter and then the datalogger functions.

Existing User Training Menu

In this program the existing user may select training from the following list:

  • User Screen Controls
  • Digital Multi-Meter
  • Datalogger
