Uei Test Instruments mcp-4 Analog Clamp-on Meter 300A 750VAC

Product Description

The UEI TEST INSTRUMENTS mcp-4 is an analog clamp-on multimeter designed for measuring AC current, AC voltage, DC voltage, and resistance on electrical and HVAC circuits. It features five AC amperage ranges spanning 0 to 300 amps, three AC voltage ranges up to 750 volts, a DC voltage range up to 75 volts, and two resistance ranges with a 30-ohm center scale. The jaw opens to 1.25 inches, accommodating standard single conductors found in residential and light commercial wiring. Accuracy is rated at plus or minus 3 percent of full scale across amps and volts ranges, making it a reliable field instrument for load and circuit verification work.

The mcp-4 is suited for use by HVAC technicians, electricians, and plumbers performing circuit diagnostics on low-voltage controls, motor circuits, line-voltage systems, and resistance checks on components such as contactors, heating elements, and motor windings. Its analog movement and multiple current ranges allow precise readings on both low-amp control circuits starting at the 0 to 6 amp range and high-amp load circuits up to 300 amps. The compact form factor and included battery make it ready for field use out of the box.

Key Features

• Five AC amperage ranges: 0 to 6, 15, 60, 150, and 300 amps for precise low- and high-amp readings
• Three AC voltage ranges up to 750 volts and one DC voltage range up to 75 volts
• Dual resistance ranges (X1 and X100) with 30-ohm center scale for component testing
• Jaw opening of 1.25 inches fits standard residential and light commercial conductors
• Accuracy of plus or minus 3 percent of full scale across current and voltage ranges
• Includes one 1.5-volt AA battery and a 0.5-amp, 0.5-ohm fuse (5 x 20 mm) for immediate deployment

Compatibility

Designed as a general-purpose analog clamp-on meter for use on single-conductor AC circuits up to 300 amps and 750 volts, and DC circuits up to 75 volts, in residential and light commercial electrical and HVAC applications.

Installation Notes

This meter is installed by licensed electricians, HVAC technicians, and qualified trades performing circuit diagnostics. Always verify that the conductor to be measured does not exceed the selected range before clamping. Do not use on circuits exceeding the rated voltage or current limits stated on the meter. Follow applicable NEC and local electrical code safety practices when working on energized conductors.
