These current clamps can be used to simplify current measurements since there is no need to switch off or break the circuit carrying the current. Instead, the clamp jaws surround the conductor while it remains energised. This makes the units ideal for commissioning and maintenance work and for routine testing or fault finding in electrical machinery, plant equipment or on cable installations. Typical applications include measuring current when balancing the load on three phase supplies or checking feeder lines in the electrical supply industry. Safety The tactile barrier indicates to the operator a safe working distance for his hand to be from live uninsulated conductors, providing added confidence when making measurements in hazardous voltage areas.

Description

The DCM clampmeters are the ideal instruments for use in the installation, maintenance, monitoring or checking of electrical systems and equipment. There are three different current clamps in the DCM range covering many applications.

The series starts with a plugin unit for basic a.c. current measurements made in conjunction with a multimeter, a volt plus current unit where the user needs the flexibility of being able to make voltage measurements as well as current measurements and a high current a.c./d.c. unit.
