3. USE
Limit the measuring time between 1000 and 1200 A : 15 minutes on, followed by 30 minutes o.
With the C100 model, which is not protected by an output limiter, do not clamp a conductor before
connecting the clamp to the corresponding measuring device. Likewise, do not disconnect the clamp
from the measuring appliance when the clamp is still attached to the cable.
Before connecting the clamp to the multimeter, check that the multimeter has an appropriate calibre.
Open the jaws and clamp the cable through which the current you wish to measure is running. Roughly
centre the cable in the jaws. Follow the direction of the arrow, if so required by the application in question.
To read the measurement, apply the appropriate reading coecient (See 4.2 “Input/output ratio”).
NB : for multi-calibre models, select the ratio which provides the best resolution and precision.
