CASE STUDY

[Iran] I work as technical safety and electrical inspection consultants, inspecting electrical installations in residential, commercial, healthcare, and industrial facilities. With my previous instrument, each time I performed an RCD test, I had to repeatedly select, configure, and run each test item manually, which made inspections time-consuming. In addition, the instrument did not feature Anti-Trip technology. As a result, RCDs would often trip unnecessarily during loop impedance testing, causing interruptions and further reducing inspection efficiency.

[Saudi Arabia] The previous methods used were complex, and there were also issues with measurement accuracy, as they required a combination of measurements and supplementary calculations to obtain results.

[Japan] We had been using an older clamp meter, which made it difficult to take measurements in areas with densely packed wiring, making circuit checks more time-consuming. Since it did not include multimeter functions, we also had to carry a separate card-type tester, which required the additional hassle of winding and managing test leads.

[Japan] We had been using a multimeter to check analog signals on equipment such as I/P converters. Since the multimeter had to be connected in series with the equipment, it was necessary to either shut down the equipment or prepare additional wiring in advance. As a result, troubleshooting typically took 30 to 60 minutes.

[Cyprus] Previously, measurement results had to be recorded manually, making data management and report generation time-consuming. In addition, I didn’t have a single instrument that could perform continuity, insulation resistance, earth resistance, and RCD tests.

[Italy] Without going over-budget, there was no multimeter that was satisfactory in every respect, including: Analog meters: transient response, precision, susceptibility to static buildup, and durability. Digital meters: readability, functions, and the operation of the auto power‑off feature.

[Japan] When using a power meter, connecting the voltage test leads to the terminals one by one was cumbersome, and we were concerned that the clips might come loose during measurement.

[Japan] We used to disconnect cables to test signal converters, which was time-consuming and required a lot of effort.

[Japan] There was an installation job for an EV/PHEV charger, but although it was installed, we were unable to verify whether the charger was functioning properly, so we had to confirm proper operation using the customer’s PHEV.
