ORDERING MEASUREMENT READINGS

At default, three measurement readings are displayed at the same time, although you can display up to four readings. See Chapters 4 and 6 for more information.

When you exceed the number of selected readings, all readings shift down one and your latest chosen measurement is placed on top. Notice that the previous bottom reading is then removed.

MEASURING FUNCTIONS NOT AVAILABLE FROM THE MEASURE MENU

There are also a few more measurements that you can only find in the Scope, Meter or EXT.mV modes. These are listed below.

Chapter 4 describes how to select the Meter and EXT.mV mode measurements, and Chapter 5 the Scope mode measurements.

Additional measurements for Meter and EXT.mV modes

Vrms AC (no DC) Measure the RMS (Root Mean Square) voltage of the input signal in Meter mode. This is done with AC-coupled input so that the DC signal component is blocked and the range is optimized for the AC signal component. The V DC reading is inhibited due to AC coupling. In some cases this measurement gives one more digit of resolution over Vrms AC (DC coupled).

dBV AC+DC (decibel Volts) Measure the voltage ratio of the AC and DC components of a signal with respect to a reference voltage in Meter mode. This is done with DC- coupled input.

dBV AC (no DC) (decibel Volts) Measure the voltage ratio of the AC component of a signal with respect to a reference voltage in Meter mode. This is done with AC- coupled input so that the DC signal component is blocked and the range is optimized for the AC sinal component.
