Earth leakage clampmeter DCM305E About

The DCM305E earth leakage clamp meter 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, and 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.

The 40 mm jaw has been designed to allow measurements on both insulated and non-insulated conductors and 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 and also includes a tactile hand barrier/hand guard in the instrument case design to help protect you when working.

A compare function is also featured which has 3 pre-set leakage limits (0.25, 0.50, 3.5 mA) which, when selected, offers a visual indication and audible warning when the pre-set limit is exceeded. Other key functions include the Data Hold feature, which helps you record measurements in areas that are difficult to access or are in poor lighting, and the "automatic power off" feature, which will switch the clamp off if no readings have been made during a 20 minute period, extending the battery life.

The instrument is pocket sized, lightweight, rugged, and easy to use, making it an ideal choice for use in the electrical industry.

FAQ's of Earth leakage clampmeter DCM305E:

Q: How do I use the DCM305E clampmeter to measure earth leakage current?

A: To measure earth leakage currents, simply open the 30mm jaw of the DCM305E and clamp it around the conductor. Ensure the device is powered on, and relevant measurement mode is selected. The 4-digit LCD will display the current reading, with a hold function available if needed.

Q: What makes the DCM305E suitable for industrial and domestic environments?

A: The clampmeter is shock resistant, has a wide measurement range (0.01mA to 60A AC), and meets IEC61010-1 CAT III 600V safety standards. These attributes ensure safe and reliable operation in both industrial and domestic installations, even under challenging conditions.

Q: When should I use the data hold function on the clampmeter?

A: The data hold function should be used when you want to freeze the measurement reading on the display. This is particularly useful when working in hard-to-reach areas or when reviewing the result after removing the meter from the conductor.

Q: Where is the optimal place to use the DCM305E for troubleshooting?

A: The clampmeter is ideal for use at distribution boards, electrical panels, and wiring entries where earth leakage or fault current detection is required. Its compact size allows it to access tight spaces with ease.

Q: What is the benefit of the auto power off feature on this device?

A: Auto power off helps conserve battery life by automatically switching off the clampmeter after a period of inactivity, reducing the risk of unintentionally draining the batteries.

Q: How does overload protection enhance the safety of the DCM305E?

A: Overload protection prevents damage to the meter and protects users from potential hazards if excessive current or voltage is present during measurements.
