ZEN50 Diodtestare

Zen 50 är en komponenttestare för zenerdioder, lavindioder, transientskydd, lysdioder och LED-slingor med upp till 50V framspänning.

Mäter zenerspänning och framspänning mellan 0 och 50V med 20mV noggrannhet.

Mäter över kort tid för att minimera uppvärmning av mätobjektet.

Valbar testström, 2mA, 5mA, 10mA och 15mA.

Drivs med ett AAA-batteri (medföljer).
