The DCM300E Earth Leakage Clamp Power Meters designed primarily to check earth leakage currents with a dedicated 30 mA range providing resolution down to 10 µA. The capabilities of the DCM300E extend to measuring currents of up to 300 A ac, making it a highly versatile instrument capable of taking current measurements in a wide variety of situations and applications.

A typical application for the DCM300E Power Meters would be the measurement of earth leakage current in a circuit where the RCD or GFCI repeatedly trips out. The measured result will quickly identify whether an excessive leakage current is causing the RCD or GFCI to trip, or if the RCD or GFCI itself is faulty. The DCM300E has 4 ranges: 30 mA, 300 mA, 30 A and 300 A with a best resolution of 0.01 mA. The analog-style bargraph of the DCM300E is very useful when monitoring changes, allowing the operator to easily interpret the rapidly changing bargraph rather than the digital display. Other key functions include the “Data Hold” feature which aids in measurements where there is a problem with accessibility or poor lighting, and the automatic power off feature that extends the battery life.

This clampmeter was also designed with safety in mind and exceeds the latest safety design standards IEC1010-2-32 and EMC requirements. Extra safety features have been designed into the DCM300E to provide a safer working environment for the user.

The large clear digits of the numeric display are complemented by a high-resolution digital bar graph, useful for trending and indicating fluctuation in measurement. The back light assists use in poorly lit areas such as distribution cupboards and corners of switch-rooms; and the data-hold feature enables use on difficult access cables, where otherwise the display may be impossible to see.

The MPQ2000 portable power quality analyser has features which make it ideal for testing power quality in any environment, including rugged, weatherproof hardware, and the ability to power off Phase A or auxiliary power.

But the hardware is not all it’s about – behind the sturdy exterior is an intelligence that is focused on minimizing errors and making your testing more efficient, with industry-leading software that enables you to quickly and easily analyse your results.

The optional removable memory capabilities allows internal recorded data to be copied directly to an external standard compact flash card using the same technology available with most of today’s digital cameras. This means that without a computer on site, data can be copied, manually or unattended, from the instrument to external memory cards, increasing the effective instrument memory storage to the size of the memory card used, and will program new configuration setups in the same, simple manner.
