Choosing your ammeter clamp

There is a wide range of criteria for choosing an ammeterclamp. The approach below is designed to help define yourrequirements and guide you naturally towards the model whichbest suits your application.

The criteria selected are classified from 1 to 6.

To choose your clamp, we advise you to followthis logic:

� Measurement of direct or alternating current?(AC/DC clamps or AC clamps tables )

� High or low currents? (see the “Input” column to define the appropriate familiesof clamps)

� On small wires or large cables? (see thediagrams at the bottom of the nextpage and only choose families withthe shapes and dimensionsrequired)

� What instrument will it be connect-ed to? (see “Input / Connection”column to choose a clamp withcompatible signal and connectionpossibilities)

� What are your other criteria? (see“Specific features” column to checkthat the clamp chosen fulfils yourrequirements perfectly)

Ammeter clamps

The widest range of IEC 1010 clamps

Our innovation, technical expertise and determination to man-ufacture top-quality products that comply with standards havemade Chauvin Arnoux the worldwide specialist in ammeterclamps.

On the next pages, you will find a table presenting the clampsfor measuring AC/DC current, followed by a diagram givingclamp form with dimensions and then another table groupinga large number of models for AC current.

As a result of their specifications, certain clamps are special-ized for specific applications.

� Clamps for oscilloscopes (BNC connectors): E3N, PAC12,PAC22, MN60, Y7N, C160, and D38N

� Clamps for leakage currents: MN73 and C173

� Process current clamps: K1 and K2

� Clamp for measurement on the secondary winding of currenttransformers: MN71

As well as these standardspecialized and unspecialized

models, “specific” versions canalso be produced on request:

Flexible current sensors

20 A / 200 A

The range is composed of 9 standard models*dedicated to the measurement of AC currentsfrom 0.5 A to 10 kA, at industrial frequencies.Each flexible core (48, 80 or 120 cm longdepending on the model) is connected by ashielded cable to a small box containing the

processing electronics and a standard 9 V bat-tery. The distance between the sockets (19 mm)facilitates direct connection to any type of mul-timeter, tester or recorder equipped with an ACvoltage input (impedance Z > 1 MΩ).The quick and simple system for opening/closing

the core makes it easy to handle even withsafety gloves.Other strong points: very lightweight (no mag-netic circuit), no saturation effect, highly accu-rate and very little phase shift (for wattmetermeasurements).

Flexibility and easy handling for clamping any conductorAmpFLEX™

* Specific models on request: consult us concerning the possiblesensitivities (mV/A) and lengths. We can also supply bare sensorsfor incorporation in assemblies including the signal processingelectronics.
