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 international
norms, particularly IEC 61010-2-032 "ammeter clamps". (See 4.6.)
2. DESCRIPTION
– Output: sockets or lead (according to model): lead length: 1.5 m and 2 m for
the MN60 model.
— Ratio switch for dual calibre models.
˜ 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.
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 coefficient (See 4.2
"Input/output ratio").
NB : for dual calibre models, select the ratio which provides the best resolution
and precision.
