Fluke ScopeMeter 190 Series II handheld portable oscilloscopes

The ScopeMeter 190 Series II handheld portable oscilloscopes are claimed to be the first four-channel scopes suitable for harsh industrial environments and safety rated for CAT III 1000V/CAT IV 600 V environments.

The four input channels are fully isolated from each other to perform differential floating measurements, a critical consideration for troubleshooting fixed-installation, three-phase power electronic devices like variable speed motor drives.

The chassis is sealed from the environment with no cooling slots or fans to expose the instrument and is IP51 dust- and drip-proof rated.

The instrument has a sampling rate up to 2.5 GSps and 400 ps resolution, and is available in 100 and 200 MHz models.

With four channels, users can inspect input signals, output signals, feedback loops or safety interlocks simultaneously. Four channels enable testing of variable speed motor drives and inverter power electronic technology used in green energy generation and transportation applications.

A Li-Ion battery enables use for up to 7 h and it has an external charger and easy-access battery door. Two USB ports, electrically isolated from measurement input circuits, make it easy to capture and share waveforms. Users can conveniently store data to a USB memory device or easily connect to a PC via the USB port and transfer waveforms or screen images for data analysis or archive.
