Description of Insulation Resistance Tester

MS5205 is complied with international safety standards for electrical safety requirements of IEC61010-1 for electronic test equipment and handheld digital multimeters and design. Press MEMO button, the meter enter Hold status automatically. The Meter have automatic power off function(Sleep mode)to conserve battery power .if there is no function change orbutton press for 10 minutes. The Meter comes out of Sleep mode when a key is pressed or when the rotary switched is changed.​


  • Display-It consists of an analog display, a main display and a secondary display. Large high-definition display with backlight function enables users to read clearly in dark environments.
  • Insulation measurement-Measurement maximum value, minimum value, average value, comparison upper limit value, comparison lower limit value, DAR, PI.
  • Data storage-The instrument can store up to 20 sets of data, and the new stored data will overwrite the original stored data when the data is stored. The stores data can be read and cleared according to user needs.
