MI 2100B power calibration system

The MI 2100B from Measurements International is designed for voltages up to 600 V and currents up to 100 A at a power factor of “zero lag through unity, to zero lead”. Fully automated, the 2100B is ideally suited for calibrating wattmeters, energy meters, watt hour meters, watt transducers and VA measurements to <30 ppm. Traceability is provided via a built-in standard resistor for in phase measurements and a standard capacitor for quadrature measurements.

The system is also suitable for calibrating its own resistance standard directly against an external standard. A controller and software are used to control the units via an IEEE488 interface. The system comes with a 1.8 meter equipment rack on castors for mobility. The rack is equipped with a pull-out drawer for placement of the Unit Under Test (UUT). All connections to the UUT are made at the front of the system. A maximum of three wattmeters can be calibrated.

The system consists of a Power Comparator (2000B), a 10 mA Phase Quadrature. Power Source (2002), Transconductance Amplifier (2701A), an Auto Ranging Current
Transformer (2003A/100), a Detector Amplifier (2001B), 2501A AC Precision Divider. An AC source with high-current option and an AC/DC transfer stand are required to measure AC voltage. Different wattmeters, DVMs and AC/DC Transfer Standards have drivers built into the system software.
