Chauvin Arnoux F402 AC-DC TRMS Clamp Meter

*Important Calibration Information: 

This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘traceable calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application. 
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required. 

Updated for 2024

Our ever-popular range of F400 & F600 clamp multimers have been upgraded and made even better! The new models F402, F404, F406, F604 and F606 have an extended operating range beyond that of the existing F400 & F600 Series, making them ideal for use in modern large-scale PV installations and applications.  

To comply with the applicable standards, the new range have a test voltage measurement range from 1000 V to 1200 V for AC and from 1000 V to 1700 V for DC or AC+DC (depending on model) and benefit from a fast 12-bit TRMS digital acquisition system, offering a high level of accuracy for a varying range of signals. 

Complete with an easy-to-read backlit LCD screen, the range is Ideal for low or medium-power low-voltage applications such as maintenance and industrial installations, with varied clamping diameters up to 60 mm and a shockproof band to protect against falls, the F models are designed to produce accurate measurements in all types of installations while providing maximum safety. 

Overview:

For an electrician, a clamp multimeter is the ideal tool for any work in the field. It is simple to use and groups all the necessary functions in a single, compact solution.
The F200 Series meets the requirements of self-employed electricians and SMIs/SMEs in the electrical sector. For medium and high power values, the
F400 and F600 Series provides maximum protection and safety whatever the measuring conditions and the type of installation.
With its large clamping diameter and current measurements up to 3,000 A, the F600 Series is ideal for distribution and transmission of low-voltage electrical energy.

To deal with the highest level of low-voltage electrical installations, the F400 Series has a high protection rating and is ideal for maintenance, testing, monitoring and diagnostics on medium-power installations.
Equipped with a fast 12-bit TRMS digital acquisition system, F402 clamps offer particularly accurate measurements whatever the signal's waveform.

The Low-Voltage, medium-power F400 Series is used in the LV electricity generation and distribution sectors, industry, railways, etc. It is also suitable for lift/elevator technicians and other lifting or transport equipment specialists.
Maintenance, inspection, monitoring, troubleshooting and connection are the main applications of the clamps in this Series.

Safe and Rugged

1,000 V CAT IV / 1,500 V CAT III, an unprecedented level of safety for clamp multimeters!
For users, that means the assurance of working in total safety and in compliance with the applicable standards. The IP54 ingress protection protects the instrument against dust, in particular, thus guaranteeing its safety level over time. The mechanical design of these clamps means they can pass
the standard test for falls from a height of 2 metres.

Performance

All the clamps in the F200, F400 and F600 Series benefit from a fast 12-bit TRMS digital acquisition system offering high measurement accuracy.
Thanks to their large bandwidth and high crest factor, these clamps provide accurate measurements whatever the signal type.

Ergonomics

The entire range is designed for one-handed use, even when wearing safety gloves. For maximum efficiency, each measurement corresponds to a specific switch position. The “1 key, 1 function” concept makes it even easier to use.
In addition, all the clamps are equipped with automatic detection of the type of signal (AC or DC) on currents, voltages and power values.

Adapter function

This helps to boost the instrument’s possibilities by using measuring sensors (light meter, I/R temperature, tachometer, etc.) with voltage output (AC or DC). A clever system allows users to read the quantity measured directly.

Phase rotation

To determine the phase order, the use of a 2-wire measuring system with a microprocessor frees users from the constraints and faults encountered with instruments based on resistive or capacitive technology, when using protective accessories (gloves, mat, etc.) or an isolating transformer.

Ripple

The Ripple is a parameter which can be used to quantify the quality of the smoothing in

the case of currents which are rectified and then smoothed. The lower the ripple, the more effective the smoothing. In the

case of a switching power supply, the voltage supplied includes residual ripple, particularly at high frequency. This ripple is harmful for electronic equipment and should be kept to a minimum.

TRMS:

A range equipped with unprecedented functions for analysis and troubleshooting

TRMS versions of Min and Max!
The Min and Max measurements are TRMS values calculated over a duration of up to 100 ms. These values are particularly useful for sizing an installation, the diameter of a supply cable, thermal protection, etc.

Peak+ and Peak-
Calculated over a duration of 1 ms, the Peak+ and Peak- values can be used to characterize the distortions affecting the signal measured. For example, they may reveal variations or even dysfunction in the installation’s behaviour.

THD and Harmonics
When troubleshooting the causes of dysfunction, knowledge of the signal’s distortion, globally (THDr or THDf) or frequentially (harmonic analysis), helps to precisely target the corrective solution required: filtering solution, oversizing, etc.
Harmonic analysis also contributes to the
prevention of fire risks.

∆REL, for a quick assessment
Comparison with a reference quantity is a quick method for assessment and analysis. The variations of a signal can be measured as a differential value or a relative value. Expressed in the unit of the quantity measured, the differential value gives the difference between the stored reference value and the measured value, while the relative value gives a proportion, expressed in %, between this difference and the value of reference. The ΔREL function can be applied to any type of measurement and can be used jointly with the Min, Max and Peak functions.

An Introduction to Chauvin Arnoux's True Inrush Function:

The True Inrush function offers a response to the following issues:

• Undersizing of the electrical conductors leading to heating, premature ageing of the insulants, potentially causing short-circuits or fires of electrical origin.
• Untimely tripping of the thermal protective systems causing malfunctions, faults or lost productivity

Because the True inrush function is more than just a means of measuring the inrush current when a motor starts up, as it also allows analysis of the overcurrents at any point in an electrical installation in operation. Present on all the models in the F200, F400 and F600 Series, the True Inrush function adapts its algorithm to suit the nature and level of the current present in the installation to enable the capture of the expected overcurrent.
The True Inrush function can be used to check that electrical installations are correctly sized in terms of both the conductors used and the protective systems implemented to reduce the risks.
The True Inrush function contributes to safety, maintenance and optimization of the operating costs of electrical installations.
