1. PRESENTATION
The MN series miniclamps are designed to measure alternating currents up
to 10 kHz, on low-powered installations, from 10 mA~ to 240 A ~. They can
be used on any multimeter or oscilloscope for the MN 60. Depending on
model (see 4.2) : single or dual calibre output, alternating current, alternating
voltage or direct voltage.
They have dual insulation or reinforced insulation and comply with interna-
tional norms, particularly IEC 1010-2-032 “ammeter clamps”. (See 4.6.)

The raised arrow on top of the unit indicates the direction of the current
flow. The current is considered to flow in the positive direction when it
flows from the current producer to the current consumer. This clamp
orientation is necessary when measuring power (measuring current in
parallel with voltage).

3. USE
Limit the measuring time between 200 and 240 A : 10 minutes on, followed
by 30 minutes off.

With the MN 08 and 09 models, 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.

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.
