Demonstration Meter
With interchangeable scales. A versatile instrument and demonstration
meter that can be converted to an a.c., or d.c. voltmeter or ammeter
with selection of various ranges for each mode.With a high quality
moving coil, spring controlled movement with full scale deflection of 5
mA or 100 mV d.c. The long pointer has a spade end and is clearly
visible from a distance. Fitted in case with glass front and back. The
instrument can be used with different dials to give different voltage
and current ranges. All dials are interchangeable and each has a plug
coupler to fit the instrument. The coupler connects appropriate
resistors, shunts or rectifiers to convert the instrument to the range
as given on the scale of the particular dial. The scales have clear bold
figures and are marked on both sides to enable the lecturer also to
observe the reading from the back of the instrument. A zero adjuster
allows the instrument to be used for centre zero dials.One dial of range
50-0-50 mV d.c. is supplied with the instrument. In wooden case
