RS PRO ICMA1 Current Clampmeter
From RS PRO, this ICMA1 Clamp meter is a high performing solution for current measurement. The clampmeter utilises Hall Effect technology and nickel steel alloy jaws for precise measurement of ac and dc current up to 300 A.
It functions as a current meter and can measure inrush current and low pass filter.
Battery-powered for maximum portability, and with a large backlit screen, this current clamp meter is ideal for on-the-go applications in almost any environment.
It is also supplied in a carry case to keep the clampmeter safe and secure during transit.
Features and Benefits
• 6000 Count large-scale LCD display with backlit
• AC-DC current measuring capability up to 300 A
• Automatically detect DCA/ACA with AC True RMS reading mode
• 10 mA Resolution
• 1.5% basic DCA/ACA accuracy
• Inrush Current Measurement for monitoring motor start-up current
• Smart Data Hold
• Low Pass Filter for variable speed drive applications
• DCA Zeroing
• Auto Power Off (20 min.)
• VoltSense™ feature (Non-contact voltage detecting)
• Up to 25 mm dia. Conductor size
Applications
This current clamp meter is designed for current measurement in electrical testing, and combines a digital multimeter with a clamping current sensor. The nature of the clamp means that it can fit around a wire at any point to sense AC and DC Current as well as inrush current. This has the advantage of allowing electricians to take a reading from a wire without touching it, which is both more convenient and safer than other methods.
They are used for measuring high levels of current in service and maintenance applications. They are also used when installing electrical equipment.
