MAKING MEASUREMENTS IN METER AND EXT.mV MODE

In Meter and EXT.mV mode you can make the same measurements as found in the Measure Menu. To find these measurements, select ADD MAIN READING in the Submenu MORE window. This opens a list of all possible measurements. For more details of the measurements, see Chapter 3.

An easy way to return to the factory default readings of the

active main mode is to press (RESET READING) from the Submenu.

Changing the number of readings

At the factory default setting the ScopeMeter test tool displays a combined numeric reading result and a waveform. You can customize the number of readings on the display from one to a maximum of four. On page 2 of the More window, highlight READINGS ON DISPLAY,

select the new number 1, 2, 3, or 4, and press to

select. Then press to remove the window again. In and modes the maximum number of readings is two.

TAKING RELATIVE READINGS (SCALING)

Scale Main Reading displays the present measurement result with respect to a defined range. From a Submenu,

press to open a MORE functions window. Next, use

or to highlight SCALE READING. When you

press , a list box appears on the display to select the

scaling function: off, ZERO (see ), ZERO %, and

0%-100%. Highlight a scaling function, and press to select.

Figure 4-6. Scaling Functions

Readings Relative to a Reference Point (Zero )

Select "ZERO " to set the present upper reading as the zero reference point. Subsequent readings are displayed as units of variation from this point. This feature is useful when you need to monitor input activity in relation to a known good value. The zero function can also be used with dBV, dBm, or dBW.

You can also activate this function from the Submenu, and

then press .
