Model 1010A Power Calibrator

Model 1010A is a power calibrator which compares a target power meter with a calibrated power meter. The system consists of a Current Transformer and a Voltage Transformer. It can calibrate power meters, for example, comparing a target power meter in the range of 0.05mW to 666.666W with a reference power meter calibrated at 100 V, 5 A.


  • Wide range of power values can be calibrated as power range is extended with one calibrated point.
  • Power Meter of 200 V (Max. 250 V) Input can be calibrated. In this case (power comparison calibration), power range is max. 1.25 kW. (Ref. Power Meter Calibration Example in Sec.3.2.)
  • Up to 100 A input power meters can be connected changing a current transformer. Max. 25 kW power comparison calibration is available. (Ref. Power Meter Calibration Example in Sec.3.3.)
  • Transformer outputs voltage with 1 ppm resolution in respect to input voltage.
  • Current transformer outputs current with 1 % resolution within 0 % to 120 % of input current.
