Why choose the Megger DCM310?
✓ Keep routine current checks simple
The DCM310 focuses on AC current measurement. It suits electrical contractors and users working on basic electrical systems and equipment.
Use it during installation, maintenance and inspection when you need a practical way to check current. The three current ranges cover readings from small currents through to 400A.
✓ Read measurements in awkward positions
A display can be difficult to see when working in a confined space. Data hold freezes the reading, giving you more time to view it.
This is useful when the position of the cable makes the screen hard to read during the measurement.
✓ Check the highest measured current
Max hold automatically keeps track of the highest value measured over a period of time. You can use that stored maximum when reviewing a current check.
The instrument samples 2.5 times per second, helping you follow current readings during a check.
✓ Carry it between jobs
The DCM310 measures 56 × 180 × 32mm and comes with a carry pouch. Its compact size makes it convenient to take between testing locations.
The instrument has an IEC/EN 61010-1 CAT III 600V safety rating. It is also rated to withstand a 1.2m drop onto a hard surface without damage.
