METERS FOR

POWER MEASUREMENTS
Reliable, simple and safe instruments. Ideally suited for the tight budget.
Digital AC Clamp-On Meters
Models MX345, MX640 and MX1240 for AC circuits combine, in compact units, three measurement functions : current, voltage (AC and DC) and resistance. The MX345 is particularly light, and can be carried easily in the pocket. The three models are equipped with HOLD functions, allowing the technician to record the displayed value and to read it later in the most accurate and safe way. They have a rate of measurement of 4 readings per second, a display of 4,000 points, an automatic range selection and a continuity beeper. They conform fully to IEC1010-1 standards in category III. To sum up, choosing one of these clamp-ons is to choose an instrument which is reliable, simple, safe and ideally suited for the tight budget.
Pocket-size MX345 Digital AC Clamp-on Meter measures current up to 400A and features a 30 mm jaw opening.
MX345 digital AC clamp-on meter features easy-to-read LCD. HOLD button freezes measurements for easier, safer reading.

A clamp-on for AC and DC circuits
The MX1140 clamp-on meter allows, for both AC and DC circuits, measurement of current (up to 1000Arms), voltages, resistance, continuity and frequencies. The use of Hall effect sensors guarantees the accuracy and precision of all measurements. Its large jaws will test conductors up to 51 mm thick. The AUTO ZERO function allows the user to reset the meter to zero quickly and easily. An audible test for continuity, automatic range selection, conformity with IEC1010 Cat.III standard and its price make the instrument ideal for industrial maintenance applications.
MX640 digital AC clampon meter provides 400A and 600A ranges and a 42 mm jaw size.
MX1140 measures AC and DC current up to 1000 Arms. Jaw opening 53 mm (max. conductor size 51mm)

Key Power Parameters At Your Fingertips

010 I1. IV CAT

Built to meet the worlds most demanding electrical challenges, Metrix MX240 and MX2040 Clamp-ons provide current, voltage, resistance, continuity and frequency measurements in the fields of repair and in the control of electrical systems. As ultimate monitoring and diagnostic tools, MX240 and MX2040 detect excessive power consumption, calculate the power factor automatically and also the value of the necessary compensation capacitor. They perform measurement of threephase systems. Conforming to the IEC1010 standard, they are the first clampon meters to meet the demands of the installation category level IV 600V.

Easy-to-use controls allow convenient and safe one-hand operation.
True RMS for accurate measurements
For the most accurate measurements, the clamp-on meter measures DC, RMS and True RMS values for all currents and voltages, even for non-sinusoidal signals.
Measures irregular wave shapes
Because of digital processing, the clamp-on meter detects and measures peaks as short as 1msec, plus Min. Max and AVG values. In addition, the meter calculates a waveforms crest factor and warns of input overload and saturation.

Measures Power Factor

The clamp-on meter calculates the power factor automatically, by determining the phase-angle between voltage and current. Dual display shows at the same time power factor with values of active, reactive or apparent power. It also calculates the value of the necessary compensation capacitor. Conversely, the meter can calculate the effect on the power factor of a particular capacitor value. Ideally the power factor should tend towards 1.
* Labview and Labwindows CVI are National Instruments Trademarks

Measures kW-Hours

An internal timer, coupled with the ability to measure power, enables the meter to accumulate measurements and calculate the energy in kWh over a duration chosen by the user.

Three-phase measurements

MX240 and MX2040 perform measurements on three-phase systems and indicate the direction of rotation, facilitating the connection of three phase motors. The sensitivity is 30V on each phase.

RS232 Interface

The RS232 interface allows readings to be sent to a printer or a PC. It can also be used to remotely control the clamp-on meter, and for the user to configure and process the results from a PC. Specific applications can be developed using LabView* and LabWindows CVI* compatible drivers. Finally, the meter recalibration is controlled by software through the interface, without needing any mechanical adjustment to the clamp meter.
Data Logger and Data Talker Modes
In Data Logger mode, the clamp-on meter can record 512 events at a programmable rate (0.5 sec. to 5 min) and output them either to a PC or to a printer, through the optional interface RS232 (option: HA1261). Also using the RS232 interface, the meter can send measurement results in Data Talker mode at a programmable rate either to a PC or to a printer.

Analog Output Port

With optional HA1268 interface, you can output a dynamic analog signal representing the current. With optional HA1260 interface, you can output analog signals either in dynamic mode (voltage, current,.), or at the display rate (power factor, energy measurements)

Built to tough European standards
Metrix MX240 and MX2040 clamp-on meters meet IEC1010, Cat. IV 600V, Cat.III 1000V, degree of pollution 2. Each meter is supplied with a Declaration of Conformity.
The power factor is the cosine of the phase angle between current and voltage, improving it enables you to use energy more efficiently and cut power costs.
