Product Description

UT-505A meter is a specialized device designed to measure insulation resistance in the range from 0.01MΩ to 20GΩ. Note: for proper measurement of insulation resistance values, the use of high voltage is required When performing the measurement, be very careful and strictly follow the recommendations in the device manual.


Resistance measurement:
  • 50 V test voltage : 0.01 MΩ ... 50 MΩ ± (3% + 5)
  • Test voltage 100 V : 0.01 MΩ ... 100 MΩ ± (3% + 5)
  • Test voltage 250 V : 0.01 MΩ ... 200 MΩ ± (1.5% + 5)
  • Test voltage 500 V : 0.01 MΩ ... 2 GΩ ± (1.5% + 5)
  • Test voltage 1000 V : 0.01 MΩ ... 20 GΩ ± (1.5% + 5)
Open circuit voltage:Test voltage + 20%
Testcurrent:1 mA
Short-circuit current:< 2 mA
AC voltage measurement:600 V ± (2% + 3) @ 0.1 V
DC voltage measurement:600 V ± (2% + 3) @ 0.1 V
Small resistance measurement:20 kΩ ± (1.5% + 3) @ 0.01 Ω
Automatic change of measurement ranges:Yes
RS-232:No
USB:No
