MX 26 - MX 24B - MX 23 - MX 22 - MX 21 2,000 to 5,000-count digital multimeters From the learning stage to professional life, tools for all generations Depending on the model: * TRMS (AC+DC) measurements for precise and accurate results * A bandwidth up to 100 kHz * An innovative design with a compact and sturdy casing * An excellent degree of readability for the results: a wide screen, a tendency display (bar graph), backlighting, etc. * Numerous functions: MIN./MAX., AVG., MEM. and/or AUTO. MEM., etc. * A unique way of accessing the batteries and fuses with improved safety mechanisms * A optical serial link for reading and processing data on the computer with a user-friendly and high-performance software package * An elastomer protective sheath along with numerous other accessories MX 26 - MX 24B - MX 23 - MX 22 - MX 21: 2,000 to 5,000-count digital multimeters Design and sturdiness Measurement storage In addition to their harmonious line, MX Concept multimeters are particularly well balanced and fit naturally into one's hand. Moreover, protected in their elastomer sheath, they are able to withstand even the most severe conditions of usage. Besides, the primary method for putting the instrument away consists in inserting it back into its sheath, thereby perfectly protecting the screen and keys. All the instruments in the MX Concept range have the MEM function. A short press on this key blocks the display, and a second short press brings the user back to the normal display. The MX 26, 24B and 23 are, moreover, equipped with an AUTO MEM function, enabling the last value measured other than zero and stable to be automatically maintained for at least 1 s. after the measuring circuit has been opened. This is particularly advantageous when the measurement points are difficult to access, forcing the user to fix his attention on the test probes. Simplicity at all levels A rotary switch and real keys suffice to offer you all the necessary functions (MIN., MAX., AVG., measurement storage, etc.). The indications marked on the keys are specially explicit so that the user might intuitively master the instrument's functionalities. Changing the battery and fuses, no longer any need to rack your brains! What can be more tedious than looking for a screwdriver to change the batterie or fuses? The MX Concept casing enables you to perform this operation quickly and easily using any utensil: coin, pen, etc. The result in the twinkling of an eye All MX Concept multimeters have a large display; in this way, the unit and the conditions of measurement (batteries too low, AC or AC+DC measurement, change of automatic range, etc.) can be specified. On the MX 26, 24B and 23, a bar graph of 34 segments instantaneously indicates the tendency of the measurement, and backlighting makes reading the result easier when the instrument is used in a poorly lit environment. Particularly easy to access, the batterie and fuses can be changed without any risk, since it is impossible to open a MX casing without having disconnected the leads beforehand. Put back in their sheath, MX Concept multimeters will put up with any treatment, even of the most severe type! Increased safety Direct display of currents A measurements Everything is safe! To begin with, the instrument automatically switches itself off after 30 minutes of it not being used (disengageable in the case of the MX 26 and 24B), which guarantees a longer life for your batterie. Then, an automatic detection mechanism indicates the presence of a voltage greater than 24 V or a current greater than 10 A (MX 26, 24B and 23). Lastly, the batterie and fuses can only be accessed if the measuring leads are disconnected. Although it has no current input, the MX 21 offers an original function which allows the measurements to be read in amps. To do this, simply use the MN 89 ammeter clamp and put the rotary switch into the clamp position. The instrument then automatically manages the transformation coefficient and directly displays the value of the AC currents. With a resolution of up to 0.1 A, the MX 22 enables very weak currents to be measured, whether they be alternative or direct. This point is highly advantageous when it comes to electronics applications. Dedicated functions In order to simplify their use, some models (MX 26, MX 24B and MX 23) have dedicated functions. Thus, when the rotary switch is positioned on ADP, these multimeters offer a 500 mVDC or AC+DC range intended for use with additional accessories: temperature probe, tachometric probe, etc. Moreover, their V low Z (low impedance) function avoids the phantom voltages we sometimes come across in electricity having to be measured. The MX 23 ready for a current measurement to be carried out With the AE0190, you have a real bag in which you will be able to put away all the tools you use on a daily basis. Communication and software Thanks to its infrared digital output, the MX 26 can be connected directly to a computer without any risk. Data acquisition is continuous The user can record the data, represent it in the form of a graph and export it, at leisure, to an Excel(R) type spreadsheet (SX-DMM2 software). He can also calibrate the instrument without opening it and edit a list mentioning all the corrections which have been made to the instrument.
