A new range of general-purpose handheld digital multimeters which combine
reliability, ease of use and safety for use in field maintenance
applications, has been introduced by Yokogawa.
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 90mm(W) x 192mm(H) x 49mm(D) and weigh
approximately 570 g (including batteries). Battery life for continuous DC
voltage measurement with alkaline cells is approximately 300 hours, says the
company.
