Analogue multimeter ranges
Analogue multimeters, like digital ones have a variety of ranges. They are described in terms of Full Scale Deflection or FSD. This is the maximum that the range can read. In order to get the best reading, it is necessary to have the scale reading somewhere between about a quarter and all of the FSD. In this way the optimum accuracy and significant number of figures can be read. As a result of this meters have a variety of ranges, that may appear to be reasonably close to each other.
A typical meter may have the following ranges (note that the figures indicate the FSD):
- DC Voltage: 2.5V, 10V, 25V, 100V, 250V, 1000V
- AC voltage: 10V, 25V, 100V, 250V, 1000V
- DC Current: 50uA, 1mA 10mW, 100mA
- Resistance: R, 100R, 10 000R
There are several points to note from this typical analogue multimeter specification:
