Permanently short-circuit-proof student measuring instrument for measuring voltage and current in the safety extra-low voltage range. The electronic overload protection is achieved without the use of an equipment fuse, therefore obviating any need to change fuses or order spares. The protective system nevertheless operates without any auxiliary energy and is guaranteed even when the battery is flat or no battery is present.
Direct and alternating voltage: 0.3 − 30 V, 5 ranges each
Direct and alternating current: 1 − 3000 mA, 5 ranges each
Instrument category: CAT I, 30 V
