Backside

General information

⚠ The safety references must be followed.

The respective accident prevention regulations established by the professional associations for electrical systems and equipment must be strictly met at all times.

Carrying out Measurements

Connection Power Supply

The respective accident prevention regulations established by the professional associations for electrical systems and equipment must be strictly met at all times.
⚠ To avoid electric shock, safety measures must be observed when working with voltages higher than 120 V (60 V) DC or 50 V (25 V) RMS AC. These are the values of threshold contact voltages given by DIN VDE. The values in brackets apply to medical and agricultural applications.
⚠️ Measurements in dangerous proximity of electrical installations are only to be executed when instructed by a responsible electrical specialist, and never alone.
⚠️ Before connecting the test leads, the measurement instrument must be set to the correct type of connection.
⚠ The correct connection assignment for voltage and current must imperatively be observed.
Phase assignment: The measurement inputs may not be exchanged. I.e. if, for example, the voltage clips for the first phase are connected to voltage input U1, the current clamp pertaining to this phase must be connected to current input I1. Observe the markings of the clamp adapters and the connection field.
⚠️ Before connecting the test leads, determine the neutral conductor for N input using an appropriate measurement instrument
The test leads and test probes may only be touched at the handles provided for this purpose. Any direct contact with the test probes must imperatively be avoided.
The measurement inputs U1, U2, and U3 are galvanically connected. Input N is the common reference point. Measurement inputs which are not required may not be connected!
When using clamp adapters, special care has to be applied that they are connected to a measurement instrument before they surround a live conductor. Open clamp adapter outputs can be dangerous for the user and can lead to the destruction of the clamp adapter, caused by high induction voltages.
When connecting clamp adapters, special care has to be applied that the arrow marked on the current clamps (direction of current flow) must point from the electric power supply to the load. I.e. the printed arrow must point to the electric power supply.

Shaft direction (X1)

If a clamp is connected in the opposite direction, the power measured at this phase would appear to be negative.

As the voltage input U1 represents the main signal for the Power Analyzer, this input must always be connected, i.e. even for measurements of U2, U3, I1, I2, and I3. If this input is not connected or if no voltage is present, the measurement instrument will not record any measurement values.

Harmonic measurement

In this window you can carry out simple harmonic measurements up to the 31st harmonic.

The total value of the harmonic distortion THD in percent is calculated according to the following equation:

% THD = 1 0 ^ where √ A (f _ 2) ^ 2 + A (f _ 3) ^ 2 + ... + A (f _ N) ^ 2A (T1) = fundamental wave, A (fn) = harmonic with number n.

The number of harmonics (n) for the calculation of THD can be selected.

Click the (g) [Insert graph] button, to open the window for the harmonic measurement.

Via the I4 input, harmonics cannot be measured.

Select the requested input frequency in the (B) window.

Click the [OK] button to start the measurement.

The values of the 64 sampling values are listed under No.s. In addition, a window with the representation of the signal curve will be displayed during the measured time interval of 20 ms (at 50 Hz).

Field "Harmonics" - Number of harmonics for the calculation of THD:

To select the requested last harmonic use the arrow keys or directly enter or modify it in the display field.

Example: If 5 is selected, the total value THD from number 1 to 5 will be calculated. The "Harmonic number 1" is identical to the fundamental wave.

"ORD%" field - ordinal number of the harmonic:

Use the arrow keys to select the requested harmonic. The percentage of this harmonic is shown in the adjacent field.

"Phase Angle" field

Phase angle between voltage and current (is calculated via Fast Fourier Transformation)

The displayed value refers to the ordinal number selected under "ORD%".

" THD-F% field: Total value " of the harmonic distortion, defined for voltage as

THD - F% (v) = √_{n = 2}⁴⁰V_n²V₁

" THD-R% field: Total value " of the harmonic distortion, defined for voltage as

THD - R% (v) = √_{n = 2}⁴⁰V_n²√_{n = 1}⁴⁰V_n²

The displayed values refer to the harmonic selected under "Harmonics".

If the distortions are only slight, both values are nearly identical.

In the "NaN" message is displayed in a window, there is no valid value.

Settings in MS EXCEL text wizard

Setting the data type: Do not select "fixed width", but "delimited".

Setting the delimiter: select Tab and text qualifier: select "none".

The data format of the second column has to be set to YMT date format.

As a result, you will receive the read raw data in the correct spreadsheet form.

Now, you can edit the data at discretion.

Maintenance

When using the instrument in compliance with the users manual, no special maintenance is required.

Cleaning

If the instrument is dirty after daily usage, it is advised to clean it by using a damp cloth and a mild household detergent

Prior to cleaning, ensure that instrument is switched off and disconnected from external voltage supply and any other instruments connected (such as UUT, control instruments, etc.).

Never use acid detergents or dissolvants for cleaning.

Calibration Interval

We suggest a calibration interval of one year. If the instrument is used very often or if it is used under rough conditions we recommend shorter intervals. If the instrument is used few times only the calibration interval can be extended on to 3 years.
