Connection is simple. The MacroEVtest is connected through the provided C100EV cable to EV-Test100, which is connected, through an in-built cable provided with type2 plug, to a recharging station.

SIMPLIFIES

EV-Test100 can simulate the presence of a car being recharged and, at the same time, communicates with MacroEVtest thanks to the new display with touch screen system fitted to HT’s latest generation instruments.

SIMULATES

To correctly perform all tests, all you need to do is following the GUIDED PROCEDURE created by HT for this innovative instrument.

GUIDES YOU

The design and production of installations increasingly takes into consideration the increase in rated voltage, which allows for the realization of strings up to 30% longer, for a higher generated power and, at the same time, uses a smaller number of components, which allows for the reduction of energy loss (BoS) up to 30%, while improving profitability.

In this way, an increasing number of photovoltaic installations are realized with a rated voltage close to 1500VDC, with a view to obtaining the maximization of all the relevant benefits, while falling, at the regulatory level, in the classification of Low Voltage systems.

Consequently, the probability of a stress on each part of the photovoltaic system generates the need of having suitable and highly performing tools for an accurate and appropriate verification of these new parameters.

This is why HT Italia has created and developed PV ISOTEST, the first and only instrument suitable to carry out, on a photovoltaic system up to 1500VDC, the most important safety checks required by standard IEC/EN62446-1, and to guarantee the quality performance a professional nowadays considers as highly indispensable.

Why True RMS?

Measuring instruments for AC are divided into two types: 

• AVERAGE-VALUE meters: instruments measuring the value of the sole wave at fundamental frequency (50 or 60 Hz). 
• TRMS (True Root Mean Square) VALUE meters

True RMS instruments measuring the TRMS value of the quantity being tested. With a perfectly sinusoidal wave, the two families of instruments provide identical results. With distorted waves, instead, the readings shall differ.

Average-value meters provide the RMS value of the sole fundamental wave; TRMS meters, instead, provide the RMS value of the whole wave, including harmonics (within the instruments bandwidth).

Therefore, by measuring the same quantity with instruments from both types, the values obtained are identical only if the wave is perfectly sinusoidal. In case it is distorted, TRMS meters shall provide higher values than the values read by average-value meters.

The HT Italia Line Splitter separates the Active (Line) from the neutral and ground wires on a standard 240VAC outlet allowing current measurements to be made with a current clamp. Without the Line Splitter, the current clamp measures the load current going in both directions, effectively cancelling the measurement.

The HT Line Splitter has a standard measurement section and a x10 multiplier section for use with higher ranged clamp meters.

The HT Italia HA000951 Line Splitter can also be used to make voltage checks safely with standard multimeter probes.
