4.0 Measurement Preparation

4-1 Opening Screen

1. When the meter is powered up the initialization screen appears asking the user to “please wait”.

2. The meter will also check for an inserted SD memory card. ‘SD check’ will appear on the screen.

If an SD card is inserted, the blinking display will switch off after several seconds. When no card

is inserted the display will show ‘No disk’.

4-2 Main Screen

The main screen displays all of the power measurement data.
