DEMONSTRATION METER |
 |
| A demonstration meter and may be converted to an a.c. or d.c. Voltmeter and 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 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. |
