71M6533-DB Demo Board User’s Manual 1.8.2 USING THE DEMO BOARD FOR ENERGY MEASUREMENTS The 71M6533-DB Demo Board was designed for use with current transformers (CT). The Demo Board may immediately be used with current transformers having 2,000:1 winding ratio and is programmed for a Kh factor of 3.2 and (see Section 1.8.4 for adjusting the Demo Board for transformers with different turns ratio). Once, voltage is applied and load current is flowing, the red LED D5 will flash each time an energy sum of 3.
71M6533-DB Demo Board User’s Manual In general, when IMAX is applied to the primary side of the CT, the voltage Vin at the IA, IB, or IC input of the 71M6533 IC is determined by the following formula: Vin = R * I = R * IMAX/N where N = transformer winding ratio, R = resistor on the secondary side If, for example, IMAX = 208A are applied to a CT with a 2500:1 ratio, only 83.2mA will be generated on the secondary side, causing only 141mV.
71M6533-DB Demo Board User’s Manual 1.9 CALIBRATION PARAMETERS 1.9.1 GENERAL CALIBRATION PROCEDURE Any calibration method can be used with the 71M6533 chips. This Demo Board User’s Manual presents calibration methods with three or five measurements as recommended methods, because they work with most manual calibration systems based on counting "pulses" (emitted by LEDs on the meter).

It is a simple text file and can be created with Notepad or an equivalent ASCII editor program. The file is executed with HyperTerminal’s Transfer->Send Text File command.
71M6533-DB Demo Board User’s Manual 1.9.5 AUTOMATIC GAINS CALIBRATION The Demo Code is able to perform a single-point fast automatic calibration, as described in section 2.2. This calibration is performed for channels A, B, and C only, not for the NEUTRAL channel. The steps required for the calibration are: 1. Enter operating values for voltage and current in I/O RAM. The voltage is entered at MPU address 0x10 (e.g. with the command )10=+2400 for 240V), the current is entered at 0x11 (e.g.

71M6533-DB Demo Board User’s Manual 2 2 APPLICATION INFORMATION 2.1 CALIBRATION THEORY A typical meter has phase and gain errors as shown by S, AXI, and AXV in Figure 2-1. Following the typical meter convention of current phase being in the lag direction, the small amount of phase lead in a typical current sensor is represented as -S. The errors shown in Figure 2-1 represent the sum of all gain and phase errors. They include errors in voltage attenuators, current sensors, and in ADC gains.

When properly interfaced, the V3P3 power supply is connected to the meter neutral and is the DC reference for each input.
71M6533-DB Demo Board User’s Manual 2.2.2 CALIBRATION PROCEDURE WITH FIVE MEASUREMENTS Each phase is calibrated individually. The calibration procedure is as follows: 1) The calibration factors for all phases are reset to their default values, i.e. CAL_In = CAL_Vn = 16384, and PHADJ_n = 0. 2) An RMS voltage Videal consistent with the meter’s nominal voltage is applied, and the RMS reading Vactual of the meter is recorded.
71M6533-DB Demo Board User’s Manual Step 1: Basic Calibration: After making sure VFEED_A, VFEED_B, and VFEED_C are zero, perform either the three measurement procedure (2.2.1) or the five measurement calibration procedure (2.2.2) described in the CT section. Perform the procedure at a current large enough that energy readings are immune from voltage coupling effects.

On the Demo Boards, this is done by plugging in a jumper at TP10 between the V1 and V3P3 pins. Programming the flash memory or emulation using the ADM51 In-Circuit-Emulator can only be done when a jumper is plugged in at TP10 between V1 and V3P3. Conversely, removing the jumper at TP10 will enable the hardware watchdog timer. 2.5.
