*Important Calibration Information:
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘traceable calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible, we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.

The DCM305E is perfect for identifying and measuring the earth leakage current in a circuit where the RCD keeps tripping out unexpectedly. The measured result will quickly identify whether the earth leakage current present is excessive, causing the RCD to trip, or if the RCD itself is over sensitive or faulty.

Specially designed to check earth leakage currents, the DCM305E is an efficient and highly versatile instrument. It has six ranges 6 mA, 60 mA, 600 mA, 6 A, 60 A, 100 A with a minimum resolution of 0.001 mA on the 6 mA range. Its upper range also enables TRMS AC current measurements up to 100 A.
Additionally, this clamp meter vastly improves measurements on circuits with harmonics/electric noise on the cables using a low pass filter of 50/60 Hz.

Safety is of the utmost importance and with that in mind, the DCM305E exceeds the latest safety design standards IEC1010-2-32 and EMC requirements through a series of safety features that provide you with a safer working environment.

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.
