The Yokogawa TY500 Series is a new range of general-purpose handheld digital multimeters which combine reliability, ease of use and safety for use in field maintenance applications. Featuring a basic accuracy of 0.09% and a 3.5-digit 6000-count backlit display with a 31-segment bar graph, the TY500 Series includes true RMS measurements as standard, along with functions such as thermocouple temperature measurement, low-pass filtering and optional current measurement using a clamp sensor.

An important contribution to field site safety is provided by safety shutters, which prevent erroneous insertion of the test leads into the current measurement terminals. The TY500 Series conforms to the requirements of the EN61010-1 safety standard (1000 V, CAT.III, 600 V CAT.IV).

There are two models in the TY500 Series: the standard Type TY520 and the advanced Type TY530. Both will measure DC voltage, AC voltage, DC current, AC current, resistance, frequency, temperature and capacitance, as well as carrying out continuity checking and diode testing. A low-pass filter is included as standard, and a direct reading current function is available via an optional current clamp sensor.

Additional features available on the TY530 including a logging-mode memory for 1600 data points, maximum/minimum/average calculation, switchable RMS/mean detection, USB communication and an optional DMM communications software package.

TY500 Series multimeters measure 90(W) x 192(H) x 49(D) mm and weigh approximately 570 g (including batteries). Battery life for continuous DC voltage measurement with alkaline cells is approximately 300 hours.
