123B/124B/125B Users Manual How to Read the Screen The screen is divided into these areas: Information, Reading, Waveform, Status, and Menu. See Table 3. Table 3. Parts of the Screen Item 1 Area Description Information Date, time, and indicators like Auto range, Hold/Run, AutoHold, and battery status. Reading Numeric readings. If only input A is on, you will see the input A readings only. Waveform Waveforms. If only input A is on, you will see the input A waveform only.
Industrial ScopeMeter® Scope and Meter Mode When you change a setup, a part of the screen shows the choices. Use WXYZ to access the menu choices. Connect-and-View™ The Connect-and-View™ function (Auto Set) enables hands-off operation to display complex unknown signals. This function optimizes the position, range, time base, and triggering to ensure a stable display on most waveforms. The setup will track the changes if the signal changes. This feature is enabled by default.

123B/124B/125B Users Manual Harmonics Measurements Harmonics are periodic distortions of voltage, current, or power sine waves. A waveform can be considered a combination of various sinewaves with different frequencies and magnitudes. The contribution of each component to the full signal is measured. Harmonics power distribution systems are often caused by non-linear loads such as switched mode DC power supplies in computers, TVs, and adjustable speed motor drives.
Industrial ScopeMeter® Power and Harmonics Mode Table 6. Harmonics Voltage Measurements Readout hxv29.eps Description rms V AC Voltage AC value on channel A THD %f THD is the amount of harmonics in a signal as a percentage of the total RMS value (THD%r) or as a percentage of the fundamental (THD%f). It is a measure of the degree to which a waveform deviates from a purely sinusoidal form. 0% indicates that there is no distortion. You can select THD%r or THD%f in the Settings menu (3).
123B/124B/125B Users Manual Table 7. Harmonics Current Measurements Readout Rms AAc Current AC value on channel A THD %f THD is the amount of harmonics in a signal as a percentage of the total RMS value (THD%r) or as a percentage of the fundamental (THD%f). It is a measure of the degree to which a waveform deviates from a purely sinusoidal form. 0 % indicates that there is no distortion. You can select THD%r or THD%f in the Settings menu (1).

In the test screen the text LIMIT will be followed by an * if any of the limits is not the default limit. Note Changed limits persist until a new change is made or the Test Tool is reset.
123B/124B/125B Users Manual The Meter Recorder makes the Test Tool act as a paperless recorder that collects a series of parameter measurements over time and shows the result as a graph or a trend-line on screen. This is most useful to understand the change of individual parameters over time or the influence of environmental changes like temperature over time. The Scope Recorder captures waveforms.
Industrial ScopeMeter® Recorder Mode 5. Use YZWX and to enter the time in hours and minutes. Events are used to determine how often the measured reading deviates from the initial reading when recording starts. It is easy to see the time of a deviation when you view the recording after it stops. 6. Use YZ to highlight Set Threshold. 7. Push and use YZ and to enter the percentage deviation for meter readings.
123B/124B/125B Users Manual Cursor Measurements Use the cursor to make precise digital measurements on the plotted graphs.

Push to stop the graph update and freeze the screen. 2. Push 2 to open the RECORDING VIEW menu. 3. Use YZ to highlight Cursor On. 4. Push to accept the change. 5. Push 4 to exit the menu. 6.
Industrial ScopeMeter® Recorder Mode Zoom In/Out on Logged Meter Data Scope Record Mode By default, the display shows a compressed view of all the data with minimum and maximum pairs for the interval that corresponds with one pixel on the display. The Scope Record mode shows all the waveform data as a long waveform of each active input. This display mode can be used to show intermittent events. Because of the deep memory, recording can be done for a long period.
123B/124B/125B Users Manual 13. To start or stop a recording, push or 4. The Test Tool continuously logs all data to memory. While recording, the display does not update since all the processing capacity is needed for recording. Note The Test Tool beeps when an event occurs. hxv39.eps 7. Use YZWX and to set the time. Events are used to determine how often a waveform deviates from the initial waveform when recording starts.
