The TA8315 Series True RMS Digital Clamp Meters are designed for professional electrical maintenance, industrial troubleshooting, HVAC servicing, and electrical installation. The series includes TA8315A, TA8315B, TA8315C, TA8315D, and TA8315E, offering True RMS measurement for accurate testing of both standard and non-linear electrical signals generated by variable frequency drives, motors, and modern electronic equipment. The series measures up to 600A AC current and 750V AC/DC voltage, while providing essential functions including resistance, capacitance, continuity, and diode testing. Depending on the model, additional features such as Non-Contact Voltage (NCV) detection, frequency, duty cycle, K-type temperature measurement, and square wave output are available, making the series suitable for applications ranging from routine electrical maintenance to advanced industrial diagnostics. A 5999/6000-count LCD display with backlight and built-in flashlight ensures clear visibility in dark electrical panels and maintenance environments. Data Hold and Relative Measurement functions simplify data recording and troubleshooting during field service. Designed in compliance with IEC safety standards, the TA8315 Series features CAT III safety protection and full-range overload protection for reliable and safe operation. Automatic ranging, auto power-off, and low battery indication improve convenience and extend battery life. Combining accuracy, versatility, and safety, the TA8315 Series is an ideal solution for electricians, maintenance engineers, industrial technicians, HVAC professionals, and electrical installers.
