Product Features:

  • Standard test conditions: temperature 20 ℃, humidity 70%, for the test results do not occur under different circumstances, can also be carried out at room temperature and humidity test
  • Current sensitivity: the pointer in the zero scale to the maximum scale (full scale position) Sensitivity 1mA ± 5%
  • Internal resistance: 50ohm ± 5%
  • Insulation resistance: the meter outer box plus electrical circuit with 500V DC plus 50M ohm above. Meter case and the electrical circuit of the insulation resistance, is 500V DC voltage test of its insulation value
  • Zero position: the meter uses the standard position, the pointer and zero-scale center of the front of the same place as the base pointer and zero scale overlap tolerance is ± 1mm
  • Equalization: The permissible error range of the meter when it is tilted 90 degrees before and after using the standard position is ± 1mm
  • Pointer adhesion: instantaneous plus full-scale current over three times the current, slowly reduced to the current sense of 1/2 of the reading, then the pointer will return to scale 1/3 scale
  • Friction: the meter plus current, slowly increase or decrease to a certain value, the error point indicates the point of ± 1mm
  • Brake: instantly plus 2/3 of the scale of the current value, from the beginning to the pointer to indicate the location of the time required within one second
