DC Electronic Loads
An adjustable electronic load gives the test engineer the ability to qualify designs, check production batches or service and repair electrical products. Many applications demand an adjustable electronic load. These include the burn-in of new devices along with general power supply, battery, fuel cell and generator testing.Both static and fully dynamic DC loads are offered. With dynamic functionality 2 levels of load current can be set. The rise and fall time can then be adjusted together with the time period spent at each level. The load can also be made to follow complex waveforms by tracking an external arbitrary oscillator input.

Resistivity Meter with Multi Electrode
POLARES
Till this moment the use of Electrical Resistivity Tomography (ERT) for geology has always been basically the same since its debut, based on the original vertical Electrical Soundings (VES) principles: applying a continuous current to two stakes inserted into the ground and measuring the corresponding voltage between other two. The applied current and thus the relative tension have always been continuous, with an inversion in polarity for each measure. The new tool POLARES uses an alternate current, instead, sinusoidal type, with an adjustable frequency.

Load Testing vs. Stress Testing
A load test is a planned test to perform a specified number of requests to a system in order to test the functionality of the system under specific levels of simultaneous requests. A load test ensures that a web system is capable of handling an expected volume of traffic, and therefore is sometimes referred to as volume testing. The goal of a load test is to prove that a system can handle the expected volume with minimal to acceptable performance degradation. The threshold of acceptable performance degradation must be defined by the testers as some value considered acceptable to the end user so that users will not bounce from the site.
