Description

Passive pointer instrument for current and voltage without amplifiers and batteries. Thus the instrument is at any time ready for use. It possesses an automatic socket barrier (ASB) against unintentional switching into different measuring types. Particularly suitable for demonstration experiments due to its large scale area and control buttons arranged ahead and behind. Analogue instrument with scale for controlling the measured values on the rear side of the device. Direct measured value display via seven available, selectable scales in 1-3 gradation, including scale for centre zero point. Large indication areas for measuring type and measuring range. Moving coil instrument (core magnet) with overload protection in all measuring ranges. Including carrying handle and hook for attachment at the demo experimentation frame (301 300).
