SM201 Precision Multimeter is a multipurpose instrument designed for laboratory and field use,
and for production testing. The optional interfaces are supplied with operating software which lets you read
data.
High speed transfer to a computer and data storage in EXCEL are possible.

| Model | Description |
|---|---|
| SM201-1/0.1 | Precision Multimeter, 0.1% accuracy |
| SM201-1/0.05 | Spectral Multimeter, 0.05% accuracy |
The SM201 Spectral Multimeter is a high performance, high accuracy multimeter that allows you to measure
current and voltage simultaneously and power for current wave forms whose fundamental is in the frequency
range 20Hz to 1kHz. The SM201 Multimeter exhibits a wide current range up to 30A.
It can be extended up to 20000A to measure the rms current of a burst, for example.
For continuous signals, harmonics 1 to 63 are computed on-line. Pre-compliance testing for the main
current
harmonics is performed by selecting averaging time "IEC555-2".
In the FLICKER operating mode the SM201 will determine short time Flicker Pst and long time
Ficker Plt.
Through the use of the analog inputs and outputs the capabilities of the Spectral Multimeter are further
enhanced. The SM201 reads eight signal inputs from transducers and controls up to four analog
outputs to
drive chart recorders.
