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.
These current clamps can be used to simplify current
measurements, 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. |
