The DOX3104 and DOX3304 oscilloscopes allow measurements to be displayed in XY mode on channels CH1/CH2   and/or   CH3/CH4 simultaneously.

This is a feature widely used in electronics.

We recommend the C.A 5231 which is available, like the C.A 5205, in a kit with a current clamp and can be used to read the current measurements directly on the multimeter.

data risposta 14/12/2015 :

The C.A 5273 is an excellent choice: like the C.A 5220G, it offers a VLowZ low-impedance voltage calibre (the new name for the Velec setting), as well as all the functions required by electricians. The shockproof protective sheath is now built-on and allows you to use the MultiFix multi-position mounting system. Like the C.A 5220G, the C.A 5273 benefits from a 3-year warranty.

Please have a look at the F201 (AAC) and F203 (AAC/ADC) models. These TRMS clamp multimeters measure AC and DC voltages, resistance and continuity, as well as temperature, and are also equipped with the revolutionary TrueInrush function for measuring overcurrents. With their CAT IV 600V rating, these models can be used to work in total safety on a wider variety of installations than their predecessors.

data risposta 14/12/2015 :

You are in the right area, as both these TRMS clamp multimeters measure AC currents and offer the same functions as the F11N and F13N models.
The final choice will depend mainly on the maximum currents to be measured. The instruments you own measured up to 700 A with a clamping diameter of 42 mm.
The F201 clamp measures up to 600 A with a clamping diameter of 34 mm, whereas the F401 model measures up to 1,000 A on cross-sections of up to 48 mm.
In addition, compared with the CAT III 600V rating of the F11N/F13N, both of these models allow you to extend the scope of your work: up to CAT IV 600V installations with the F201 and up to CAT IV 1000V installations with the F401.

data risposta 14/12/2015 :

With its 1,000 A AC/DC, TRMS acquisition system and use on installations up to 1,000V CAT IV with an IP54 protection rating, the ideal model to replace the well-known F15 is the F403.

The C.A 740N and C.A 760N models are the result of a change in the standards after implementation of Edition 2 of the IEC/EN 61243-3 standard.
The IEC/EN 61243-3 standard defines the usage and the functional and technical specifications of the Voltage Absence Testers used during the separation procedure for an electrical installation.
This new edition of the standard requires the addition of a separate, redundant voltage detection system, which is why the ELV (Extra Low Voltage) LED has been added on the C.A 740N and C.A 760N models.
Similarly, the RCD trip function up to 30 mA has also been removed on the C.A 760N because of a change in the standards.

Although this change has been mandatory for measuring instrument and tester manufacturers since 1st May 2013, the standards and the law do not prohibit the use of instruments from the previous generation and there is no danger in doing so.

The C.A 740N and C.A 760N also include a few other modifications:
- automatic switching in continuity detection mode if no voltage is present
- extended continuity testing with an indication for R < 2 kΩ, 60 kΩ and 300 kΩ

The F205 clamp multimeter is a good replacement for these 2 models because it offers measurement of the W, var, VA and var power values for single and balanced three-phase configurations, phase rotation direction testing and THD measurement, as well as the revolutionary TrueInrush function for measuring overcurrents.
The F205 clamp can be used for measurements with currents up to 600 A. On higher-powered installations, you should choose the F405 or F605 which offer the same functions for currents up to 1,000 A and 2,000 A, respectively.

The Vunb parameter can  be used to qualify the level of unbalance on a three-phase network.

To calculate the unbalance Vunb, the instrument takes into account: 
- The unbalance due to the values of the three phases
- The pahse shift between the three phases
- Correct connection of the three phases

- Formula:

Where Vunb is the unblance, Vi is the negative phase sequence and Vd is the positive phase sequence of the three-phase network. 

If Vunb = 100%, it means that:
- One phase is disconnected
- Two or more phases are inverted 
- Several of the Qualistar+ voltage inputs are on the same phase

Hello,

The current source of the instrument is protected against overheating.

If a 10 A measurement lasts too long (more than several tens of seconds), it causes the temperature to rise, so the current is cut off and the instrument displays Err 05.

The instrument must be left to cool down before performing another measurement. This is a safety feature to prevent damage to the instrument.

Il sensore AmpFlex è un trasformatore progettato sul principio della bobina di Rogowski. Il conduttore di corrente alternata da misurare forma il circuito primario, mentre il secondario è formato da un avvolgimento speciale realizzato su un supporto flessibile. Questa bobina sviluppa sui suoi morsetti una tensione proporzionale alla derivata della corrente primaria da misurare, questa tensione è allora portata da un cavo schermato alla scatola contenente tutta l'elettronica di trattamento e la pila d'alimentazione.

Premete all’avvio MAX/MIN + A per la modifica del valore soglia di rivelazione corrente di misura Inrush. I valori per difetto sono del 10%, ossia 100A per F407 e 200A per F607. I valori possibili vanno dall’1% al 99%.

data risposta 02/06/2014 :

All’avvio, premete 2nd + W: questa manipolazione modificherà il passo di registrazione in EEPROM (memoria morta dello strumento). Il valore per difetto è di 60 secondi e i valori possibili vanno da 1 secondo à 600 secondi (ossia 10mn).

Per una prima connessione, occorre digitare il codice 0000 nella finestra del gestore Bluetooth. La comunicazione si stabilisce poi automaticamente.

data risposta 02/06/2014 :

L’alimentazione del vostro armadio di distribuzione elettrica è in trifase quindi siete in CAT III e 600V rispetto alla terra in generale, e la vostra presa 230V è in CAT II. Handscope propone vie isolate rispetto alla terra e le vie fra loro 600V RMS rispetto alla terra quindi potete, senza problemi né rischi, raffrontare questi 2 punti di misura.

data risposta 02/06/2014 :

Con un doppio clic sulla via A, B o M potete occultare la via voluta. Per farla riapparire, premete per 2 secondi la stessa via.

data risposta 02/06/2014 :

Vi proponiamo una pinza MiniFlex MA100 per la misura di corrente 100A su una delle vie e per la misura di tensione 230V direttamente sull’altra via. La selezione della modalità multimetro con la funzione potenza, vi permette di scegliere il vostro montaggio monofase, ottenete allora una misura di potenza attiva VA e con la selezione di “SURV”, avete i valori MIN/MAX/AVG e la tendenza di questa potenza.

NOCT corrisponde alla temperatura nominale di funzionamento della cellula. GAMMA è il coefficiente di potenza rispetto alla temperatura del modulo PV. Questi due valori sono i dati forniti dal fabbricante dei pannelli fotovoltaici.
