Chapter 2 Front-Panel Menu Operation

To Use Reading Memory

To Use Reading Memory

The multimeter can store up to 512 readings in internal memory.

The following steps demonstrate how to store readings and retrieve them.

1Select the function.

Select any measurement function. You can also select Null, Min–Max, dB, dBm, or limit test. You can change the function at any time during reading memory.

2Select the single trigger mode.

Notice that the Trig annunciator turns on. When reading memory is enabled, readings are stored when you trigger the multimeter.

For this example, single triggering is used to store readings. You can also use auto triggering or reading hold.

3Turn on the menu.

A: MEAS MENU

4Move across to the SYS MENU choice on this level.

D: SYS MENU

5Move down to a level to the RDGS STORE command.

7Save the change and exit the menu.

Notice that the Mem (memory) annunciator turns on to indicate that the multimeter is ready to store readings. Up to 512 readings can be stored in first-in-first-out (FIFO) order. When memory is full, the Mem annunciator will turn off.

Readings are preserved until you re-enable reading memory at another time, turn off the power, or perform a remote interface reset.

8Trigger the multimeter three times.

This stores three readings in memory.

9Use menu recall to retrieve the stored readings.

This takes you to the “SAVED RDGS” command in the SYS MENU.

10 Move down a level to view the first stored reading.

Reading memory is automatically turned off when you go to the “parameter” level in the menu.

The first reading displayed is the first reading that was stored (FIFO). If no readings are stored in memory, “EMPTY” is displayed. The stored

readings are displayed with their units ( , m, k, etc.) when appropriate. For example:

Features and Functions

You will find that this chapter makes it easy to look up all the details about a particular feature of the multimeter. Whether you are operating the multimeter from the front panel or from the remote interface, this chapter will be useful. This chapter is divided into the following sections:

Measurement Configuration, starting on page 51

Math Operations, starting on page 63

Triggering, starting on page 71

System-Related Operations, starting on page 84

Remote Interface Configuration, starting on page 91

Calibration Overview, starting on page 95

Operator Maintenance, starting on page 100

Power-On and Reset State, on page 101

Some knowledge of the front-panel menu will be helpful before you read this chapter. If you have not already read chapter 2, “Front-Panel Menu Operation,” starting on page 25, you may want to read it now. Chapter 4, “Remote Interface Reference,” starting on page 103, lists the syntax for the SCPI commands available to program the multimeter.

Throughout this manual, the following conventions are used for SCPI command syntax for remote interface programming.

Square brackets ( [ ] ) indicate optional keywords or parameters.

Braces ( { } ) enclose parameters within a command string.

Triangle brackets ( < > ) indicate that you must substitute a value for the enclosed parameter.

A vertical bar ( | ) separates multiple parameter choices.
