Returning to Factory Defaults

Your meter comes with the setup options preset at the factory. These factory settings are shown in Tables 5-1 and 5-2. You can always return to these settings as follows:

1.Press O T until Fcty appears in the display.

2.Press % to select yE5; press T to select no.

If you select yE5, all setup options revert to the factory defaults; you cannot specify individual choices.

3.Press O T to exit the setup procedure and activate your selection.

If you selected yE5 in step 2, all factory settings are restored.

If you selected no, selections made in the Setup mode become active.

Saving Setup Options

At each setup option, store your choice and advance to the next option by pressing O T.

If you are storing the last option, this also exits the setup mode.

To exit the Setup mode without saving the present option, press O N(CANCEL).

Selections that were previously saved with O T are retained.
