Very Happy with my earlier first sample;
Therfore, I bought this second one!
Nice form/colour :
Sturdy made (Metal house, chromed handle and screws).
Easy to regulate (and reproducibly accurate)
Voltage Range : (in 230V AC/50Hz Country: NL) : 0-329 V AC
Internal Digital Voltmeter has some limitations:
Accurate within 1% : Between 160 V and 250V OK!
Accurate within 2% : Over 140V AC OK!
Accurate within 5% : Over 90 V AC OK!
Do NOT read off meter for voltages < 90V; Inaccuracy upto 65% at 10V AC, going down to 15% at 40V !
Hence, preferably, always use external DMM to read out Output Voltage!
