Fluke 190-102-III Cal Portable Oscilloscope 100 Mhz

Product Description

The FLUKE 190-102-III CAL is a portable oscilloscope designed for field and bench diagnostics across electrical, HVAC, and industrial control applications. It delivers a 100 MHz bandwidth across 2 independent channels, allowing technicians to capture and compare waveforms simultaneously. The LCD display provides clear signal visualization in both indoor and outdoor environments. With a vertical deflection range of 2 to 100 millivolts per division, it handles a wide range of signal amplitudes without requiring a separate bench instrument. This unit is built for licensed electricians, controls technicians, and field service professionals who need reliable waveform analysis away from a fixed shop setup.

This oscilloscope suits residential and commercial applications where portable test equipment is required. Common use cases include diagnosing variable frequency drives, verifying low-voltage control signals in HVAC systems, troubleshooting ECM motor drive waveforms, and validating electrical panel outputs. It is equally at home on a mechanical room floor or a rooftop unit service call. The CAL designation indicates the unit ships with a calibration certificate, making it appropriate for environments where calibrated test equipment is required for compliance or quality assurance purposes.

Key Features

• 100 MHz bandwidth supports capture of fast-switching waveforms on motor drives and control circuits
• 2 independent input channels allow simultaneous dual-signal comparison
• Vertical deflection range of 2 to 100 millivolts per division accommodates low-level and higher-amplitude signals
• LCD display delivers readable waveform output in varied lighting conditions
• Portable form factor supports field service without requiring bench setup
• Includes calibration certificate for use in regulated or quality-controlled environments

Compatibility

Designed as a portable handheld oscilloscope suitable for general electrical and controls diagnostics in commercial and residential trade service applications.

Installation Notes

This instrument is operated by licensed electricians and qualified controls technicians. Always de-energize circuits before attaching or removing test probes where safe to do so, and follow NFPA 70E arc flash safety guidelines when working on energized equipment. Verify probe ratings are appropriate for the voltage levels being tested before connection. Store the unit in its protective case when not in use to maintain calibration integrity.
