Q: Are the encoders accurate? When you turn the knobs, is the response correct or do the parameters advance in spurts? Are they reliable over time?

Apparecchio molto semplice da utilizzare e pratiche le informazioni che fornisce, valore attuale, massimo, medio e il diagramma degli ultimi 4 minuti per capire le variazioni nel breve. Ottima anche la misura del valore cumulativo e gli allarmi programmabili. In breve lo consiglio.

Oscilloscope section Very simple to use, automatic measurements shows all those you need Convenient automatic setting button, in a short time it displays whatever waveform you are measuring It can analyze waveforms up to 700 V RMS without additional accessories. With an traditional oscilloscope this is not so easy. Beautiful backlight, very sharp display. Battery power makes it safe and avoids interference with the AC power supply (220V) Multimeter section Valid and versatile tool also as a multimeter, 6000 measuring points. Very convenient the possibility of relative measures, for example for resistance measures automatically subtract the resistance of the tips and you can read the real value. Conclusion It does not totally replace an desktop oscilloscope but its practicality of use will make you use it more than a fixed tool. In the photo it is connected to an amperometric clamp that generates a square wave of 5000 Hz. Note the perfect square wave, that indicates a really large bandwide I suggest to buy. It is a new instrument concept very useful

Very complete and compact tool. Practically replaces normal multimeters both in the laboratory and outside use Like all amperometric clamps the reading is not as stable as using a shunt but the practicality is excellent. The only defect, the backlight of only 15 sec is too short. Much better if it had been possible to keep it on without time limits. Picture shows it generating a 5000Hz square signal connected to a portable oscilloscope

Very useful if, like me, sometime loose or broke battery cover. A good instrument must be kept full operative and battery cover is an important issue.
