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. Harmonics can cause transformers, conductors, and motors to overheat.

In the Harmonics function, the Test Tool measures harmonics to the 51 components, THD (Total Harmonic Distortion), and K factor are measured.

You can display the harmonics of:

• Voltage measurements on Input A

• Current measurements on Input B

• Power measurements calculated from Voltage

measurements on Input A and Current measurements on Input B.

. Related data such as DC

In the Harmonics mode the Test Tool always uses the AUTO mode. The vertical sensitivity range and the time base range are automatically adjusted to the most suitable range for the applied input signal. The ranging keys ( /  / ) and  are locked.

Input A is forced to measure voltage. Input B is forced to measure current.

To make harmonics measurements:

1. Push 2 to select the harmonics display.

2. Push 1 to toggle between the voltage, current or

power readings.

3. Push 4 to turn on the cursor.

When the harmonics display with voltage measurements is selected, the screen shows as in Table 6. For harmonics display when current measurements are selected, see Table 7. For harmonics display when watts measurements are selected, see Table 8.

The Test Tool offers recording and logging functionality:

• Meter Recorder to log meter readings over a long period of time.

• Scope Recorder to continuously log waveforms for a long period of time without time gaps (as is the case in Scope and Meter mode).

Page 60

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. The applied input voltage is registered over time and the resulting waveform is stored in a long memory record. This can be used to capture intermittent problems. Deviations from the original signal are stored as events that can be easily viewed after recording without the need to check all information.

Start and Stop Meter Recording

Before you record, apply a stable signal to input A and B.

To set the parameters for recording:

1. Push  to open the Recorder button bar.

To jump between the start of discrete events:

1. Push 3 to select Events < >.

2. Use WX to jump between events. The readings on

the top positions will mark the value at the start of the event.

Scope Record Mode

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. The Test Tool stores 1 sample/channel for each sample time. Defining event thresholds allows you to quickly view details of the signal that deviate from the normal signal.

Cursor Measurements, Zoom, and Events are available in the Scope Record mode.

Tips

This section is information and tips on how to best use the Test Tool.

Battery Life

For battery operation, the Test Tool conserves power by shutting itself down. If you have not pressed a key for at least 30 minutes, the Test Tool turns itself off automatically.

Automatic power shutdown will not occur if Record is on, but the backlight will dim. Recording continues if the battery is low. Retention of memories is not jeopardized.

To save battery life without automatic power shutdown you can use the display AUTO-off option. The display turns off after the selected time (30 seconds or 5 minutes).

Note

If the power adapter is connected, automatic power shutdown and the display AUTO-off function is disabled.

Power Off Timer

By default, the power off timer is set to 30 minutes after the last key press. To change the time to 5 minutes or turn off:

1. Push  to open the Menu.

Grounding Guidelines

XW Warning

To prevent possible electrical shock, fire, or personal injury, use only one COM (common) connection to COM

Incorrect grounding can cause problems. Use these guidelines for proper grounding:

• Use the short ground leads when measuring DC or AC signals on input A and input B. See Figure 8, item 4 on page 17.

• Use the unshielded black ground lead to COM (common) for Ohm (Ω), Continuity, Diode, and Capacitance measurements. See Figure 7, item 1 on page 16.

• Use of the unshielded ground lead is also possible for single or dual input measurements for waveforms with a frequency up to 1 MHz. This may add some hum or noise to the waveform display due to the unshielded ground lead.
