Using the Instrument

While familiarizing yourself with the instrument you will find it useful to observe the outputs on an oscilloscope. For most purposes it is sufficient to connect the MAIN OUT front panel socket to the oscilloscope's Y input, and the AUX OUT front panel socket to the oscilloscope's trigger input.

If no oscilloscope is available you can still learn a great deal about the instrument settings, since the effect of front-panel operations is visible in the LCD display in the form of text messages, parameter information, menus and status information.

Starting up

The ac supply on/off switch is located at the bottom left side of the front panel.

Caution

Before connecting to the ac supply, check that the supply voltage setting is correct for the region. Please refer to the Users Manual if it needs to be changed.

Plug in and switch on the instrument

On power-up the LCD panel illuminates and the instrument performs a series of self tests. In the event that an error message is displayed please refer to the Users Manual.

Check the LCD Display

It should look similar to the main menu shown in figure 1. If not, press RECALL, 0, ENTER to bring up the factory default main menu.
