Digital Multimetetrs
-
The digital multimeter (DMM) is the all-rounder of electronic measurement technology. It is used to measure the basic electrical variables of voltage, current and resistance potential-free. Many devices also offer a wide range of additional functions, such as the measurement of electrical capacity, test functions for diodes or transistors and much more. Some devices also allow to record signal curves, which is equivalent to the function of an isolated digitizer.

LV Iron Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.

LIV – High-power Laser Diode Testing
-
An important aspect of the development and manufacture of laser diodes is the so-called laser diode characterization, or laser IV curve. By applying increasing current to the laser diode so it that emits light, the optical output is measured together with the voltage drop across the diode element. The resulting LIV curve reveals important clues about the quality of manufacture and the performance of the laser diode, enabling a pass/fail decision to be met.
