Oscilloscopes troubleshoot
variable-speed drives
With safety certification to 1000V CAT II and 600V CAT III, Fluke ScopeMeters help users to safely solve virtually all electronics measurement problems encountered in the field.
To verify that the voltage/frequency ratio is constant over the working range of a variable speed drive (VSD), the Vpwm function available on some Fluke 190 Series ScopeMeters gives a true measurement of the voltage actually applied to the motor, while simultaneously measuring the frequency The use of a true-rms voltmeter in these circumstances would give an erroneous reading of the full bandwidth signal

The ScopeMeter 190 Series offers up to 200 MHz bandwidth, and two digitizers provide 2.5 GS/s real-time sampling at both isolated inputs simultaneously for accurate waveform representation.
The Connect-and-View triggering of the ScopeMeter also ensures a stable display, whereas the complex modulated waveforms produced by VSDs often make it difficult to obtain a stable picture on other oscilloscopes.
With safety certification to 1000V CAT II and 600V CAT III, Fluke ScopeMeters help users to safely solve virtually all electronics measurement problems encountered in the field.
The Fluke ScopeMeter 190 Series of handheld, two-channel oscilloscopes include 196 and 199 models, and available with either monochrome or colour screens.
The 196 and 199 models offer 100MHz or 200MHz bandwidths and 1GS/s or 2.5GS/s sampling rates respectively, as well as providing a true-rms multimeter in one affordable, easy to use instrument.
The high-resolution waveforms also can be transferred to a PC running optional FlukeView ScopeMeter software for documenting, archiving and analysis. Request a free brochure from Fluke (UK) ...
