Installation Safety

Elma Combitest 421 is an innovative multifunction installation tester designed to perform all safety tests on electrical installations in compliance with safety standards (VDE0100, BS7671). Furthermore the instrument is a 1 phase energy analyze and is capable of saving results of environmental parameters (illuminance, temperature), leakage current, active power, harmonics, power factor measurements on single phase systems. The instrument is very user-friendly, extremely rugged thanks to its newest electronic range selector and provided with a wide number of features which are selectable through the multi-language menu. Moreover the model allows to carry out main measurements by using a special remote switch probe (optional accessory) particularly useful to perform tests in rapid succession as well as AUTO function to perform sequential measurements of global earth resistance, test on RCDs up to 1A rated current and insulation directly on sockets. A help menu selectable by user is available for each measurement granting information during connection between meter and installations. A wide internal memory permits saving any measurement and later transferring them to PC through USB port with dedicated software (Optional). Each measurement can be saved with all sub-results and test parameters with two ID locators (selectable by user) in order to trace the exact point where the measurement was performed

Elma Combitest 425 is an innovative multifunction installation tester capable of carrying out safety tests on civil and industrial electric systems in compliance with IEC/EN61557-1. Furthermore the instrument is a 1 phase energy analyze and is capable of saving results of environmental parameters (illuminance, temperature), leakage current, active power, harmonics, power factor measurements on single phase systems, pre-installed autosequences, 6mA RCD test suitable for EVSE Electric Vehicle chargers,. The resistive TFT color touch-screen display, the icon menues, the on screen help and the userfriendly development make the instrument extremely intuitive even for unskilled users. Its numberless features grant the user a wide range of applications in the world of measurements. The multifunction installation tester Elma Combitest 425 allows saving all measures into an internal memory so transferring the saved data to a PC by means of USB (optional) or built in WiFi interface with an iOS or Android smartphones or tablet . The software supplied among standard accessories allows printing the testing reports. The instrument also drives optional short circuit adapter to carry out high resolution (0.1mOhm) loop/line impedance measurements with prospective short-circuit current calculation. This allows accurate measurements even close to power stations enabling the user to correctly size the protection devices in any system. Further possible tests consist in checking breakdown current, tripping current, I2t relative to breakers (MCB) with curves B, C, D, K and fuses type gG as well as aM and the percentage voltage drop on the main power lines. The test on earth leakage relay tester RCDs up to 10A (with optional accessory) is also possible with the instrument. Through optional clamp it is possible to measure the leakage current.

Elma Macrotest G3 sets new standards for the demands of installation safety testers. Elma Macrotest G3 is first mover when it comes to touch responsive instruments, making navigation, test and documentation a piece of cake. Elma Macrotest G3 is ready for the future, providing test of type B RCD’s, build in fuse characteristics, I2t calculation of energy before fuse break, naming of tests for documentation with comments, pre-installed autosequences, 6mA RCD test suitable for EVSE Electric Vehicle chargers, and innovative communication via WiFi. Furthermore, the instrument is compatible with leakage current and current clamps (Accessories), directly measuring and documenting e.g. problematic leakage currents. Furthermore the instrument becomes a full-blown, 1 direct phase energy analyzer, measuring voltage, current, powers (1 phase and 3 phase balanced) cos phi and harmonics to 25.
