Shunts for Basic Student Meter (B8H30481) and Centre-Zero Meters (B8H30981). Range: 2A/10A d.c. One of a set of shunts and multipliers developed to withstand overloads resulting from common student errors. Tough Shunts cover the ranges of voltage and current commonly required in practical work. d.c. Ammeter Attachments: these units consist of suitable resistor networks mounted in a grey component channel fitted with three 4mm terminals as a common positive with two ranges. d.c. Voltmeter Attachments: similar to the d.c. ammeter attachments described above except that the two resistor networks are arranged to have a common negative terminal. a.c. Voltmeter and Ammeter Attachments: similar to their d.c. equivalents except that appropriate rectifying or transformer circuits are included designed for 50/60Hz circuits.
