  • Page 20: Calibration Procedure

    Calibration Procedure Recalibrate the meter: It is recommended that the meter may be calibrated once year. Use the following procedure to calibrate the meter. Environmental Condition Perform calibration at an ambient temperature and relative humidity (23°C±2°C and R.H. < 80%). Allow the instrument to sit at this temperature for at least thirty minutes.
  • Page 21 (E) DCA Calibration (VR7) Rotate the rotary switch to DCA Function. Connect the output of a DCA calibrator to V and COM input terminals of the meter. Output DCA 5.000A from the calibrator. Adjust VR7 until the display shows 5.000A ± 0.001A. Turn off the output of the calibrator and disconnect the meter from the calibrator.
