With an operating temperature range from -20°C to +55°C, the protection class IP54 and double insulation that devices can be even under difficult conditions. The MTX, and MTX 203 thus fulfill all the requirements of electrical 202 craftsmen for the usual measurements (voltage, current, resistance…). For the daily applications, the device fits comfortably in the hand and can be easily tucked away in the Tool Box to the electrician for all work on site. With the MTX202 and MTX203 can installation and maintenance also measure temperatures. The standard temperature sensor supplied with K thermo element can be used, for example, the control of heating systems. Maintenance work on electrical installations in offices or commercial buildings by the voltage measurement with low impedance, since it simplifies VLowZ phantom feeds, which often occurs in computer networks, reliable suppressed. The fault finding on electronic components is also easily possible by measuring the resistance, capacity, diode test, etc… Due to the ease of use are the MTX 202 & MTX 203 especially for maintenance engineer interesting quickly finding faulty components or connections. The safety of the user is in any case, the NCV function guarantees, the contact-free the existence of dangerous voltages by color change of the screen displays. This can easily be 230V-live mains cables.This text is machine translated.
