CASE STUDY

[Japan] A breaker unintentionally tripped, and identifying the cause was difficult.

[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.

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

[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.

[India] With our existing multimeters, we frequently experienced issues with erroneous readings, which reduced the reliability of electrical diagnostics during powertrain testing and sometimes even led to misleading conclusions. In addition, the manual range-selection knob required us to repeatedly switch between voltage ranges during testing, making the process slow and cumbersome, and significantly decreasing our overall efficiency.

[Syria] We faced time-consuming measurements due to the need for manual range selection, as well as difficulty working in tight spaces (e.g., in crowded electrical panels). Additionally, we sometimes experienced concerns about accuracy and safety with our old equipment.

[Saudi Arabia] I have been struggling with lower-quality measuring instruments that provide unstable readings in high-temperature and high-humidity environments. I often had to repeat tests multiple times to feel confident in the results, which wasted time on-site. I previously used instruments with poor ergonomics and weak cable connections. In tight electrical panels, common clamp meters were difficult to handle.

[Japan] Cables are crowded in the distribution board and power distribution board and we couldn't clamp the target cables. There's no space to put the clamp jaws into the crowded area.

[Japan] When testing transducers (convertors) in a distribution board, there are cases where the central monitoring system cannot be started up. In such situations, the output wiring of the transducer was disconnected and a digital multimeter was connected for measurement.  Similarly, when abnormal readings appeared on the central monitoring system on a board in operation, disconnecting the transducer output wiring during operation posed a high risk. Therefore, transducer testing was carried out during scheduled power outages to check for any malfunctions.
