Measuring Ac Current; Measuring Dc Current - Metrix MX 350 Notice De Fonctionnement

Chapter II

4.3. Measuring AC current

Set the switch to A~.
Open the clamp by pressing the trigger.
Place the clamp around the conductor to be measured
and release the trigger; check that the clamp is closed
properly. Read the result of the measurement on the
display.
Note: For safety reasons, disconnect the measuring
leads before performing this operation. The clamp
must be positioned around a single conductor in a
circuit, with the risk of rendering the measurement
incorrect. The best measurement is obtained with the
conductor centred in the middle of the jaws.

4.4. Measuring DC current

(MX 355)
Open the jaws of the clamp by pressing the trigger
and insert the cable to be measured between them.
Close the clamp and read the result of the
measurement on
Note: For safety reasons, disconnect the measuring
leads before performing this operation. If reading is
difficult, press the HOLD button and read the result
afterwards.
MX 350 / MX 355
Before measuring
currents higher than
40 A, set the scale
to 400 A by
pressing the
RANGE button.
Then reset to zero
(see § 3.2)
