HIBOK-89C DIGITAL MULTIMETER

Function and technical context

The HIBOK-89C digital multimeter is a precision electronic measurement instrument designed specifically for the diagnosis and maintenance of electrical and electronic systems on board vessels. He works on DC and AC voltage systems, current, resistance, capacities, frequencies and diode testing, covering practically all the magnitudes that a nautical technician needs to verify in engine circuits, electrical panels, batteries, chargers and navigation equipment. Its most notable feature for the marine environment is the generation of its own power through a built-in manual crank: 20 seconds of turning generates enough autonomy for 10 minutes of continuous work without the need for a battery, which makes it essential equipment when the multimeter battery runs out at sea or in difficult-to-access areas of the hull. The autoranging function with automatic AC/DC voltage detection and the large 46x45 mm screen facilitate fast and reliable readings even in the adverse lighting conditions common in the engine room.

When to use or review this instrument?

The digital multimeter is the first resort for symptoms such as slow or failed engine starting, irregularly flashing deck lights, fuses that blow repeatedly or erroneous readings on navigation instruments, as it allows you to diagnose in the field if the problem is voltage, continuity or resistance without disassembling components. It is recommended to include it in the tool kit of each boat and verify its correct operation at the beginning of each nautical season, checking both the battery mode and the manual generator to guarantee total availability in any circumstance. Having a diagnostic multimeter on board avoids prolonged immobilization due to electrical breakdowns which, detected in time, mean a simple repair in the face of a trailer or an emergency stop in port.
