Hot Line Coil Winding Resistance Meter


DAC-HRE-1 is designed for temperature rise tests of motors, transformers, coils and chokes under energizing AC voltage. The direct reading of resistance is possible with 4-terminals measurement method, and temperature is calculated from measured resistance values.


● Automatic Test with PC through RS 232C interface.
● Temperature rise test of electric coils under energizing AC Voltage Max 450V.(*)
  (*) AC Max 700V (sine wave) is available by using an optional adaptor.
● By using an optional thermal printer kit, print-out of measured values and temperature conversion values is possible. Also, print-out every given time is available with an interval mode.
● In accordance with JIS 5311 : Testing methods of power transformers for electronic equipment.
