Make a New Meter

How To... > Create Experiments > Work with Meters > Make a New Meter

There are several ways to make a new meter.

•If there are no sensors plugged in, click on the meter icon in the shelf. A pop-up menu appears. Select a meter from the list and drop it into your document.

•If there is a sensor plugged in, click on the meter icon in the shelf. An object will appear for the connected sensor; drop it into your document.

•Go to the Object | New menu and choose the type of meter you want. If a sensor for this meter is plugged into the computer, the meter name will appear above the line (see Connect Sensors). Drop it into your document.

•If Fathom is running when you plug in a sensor, a new meter for it will be automatically created in the active document. If there is already a meter of the correct type in the document, then the sensor will be assigned to that meter instead (see Connect Sensors).

Connecting Photogates

If you have a photogate connected but the meter name does not appear above the line or you do not get the automatic meter appearance, then your photogate is a non-auto-id photogate. In this case, you need to select the photogate meter from the list under the line in the menu. Fathom also assumes that the first photogate meter corresponds to a photogate in Channel 1. If you have only one non-auto-id photogate then make sure it is attached to Channel 1.

To rename a meter, double-click the name and type a new one.

To change meter properties, double-click anywhere in the meter to show the meter's inspector.

To collect data from the meter, you need to connect the meter to a collection (see Collect Values from a Meter ).
