2.2.2 CALIBRATION PROCEDURE WITH FIVE MEASUREMENTS
The calibration procedure is as follows:
1)
2)
3)
4)
5)
6)
7)
8)
All calibration factors are reset to their default values, i.e. CAL_IA = CAL_VA = 16384, and
PHADJ_A = 0.
An RMS voltage V ideal consistent with the meter’s nominal voltage is applied, and the RMS reading
V actual of the meter is recorded. The voltage reading error Axv is determined as
Axv = (V actual - V ideal ) / V ideal
Apply the nominal load current at phase angles 0°, 60°, 180° and –60° (-300°). Measure the Wh
energy each time and record the errors E 0 , E 60 , E 180 , and E 300 .
Calculate the new calibration factors CAL_IA, CAL_VA, and PHADJ_A, using the formulae
presented in section 2.1.2 or using the spreadsheet presented in section 2.2.3.
Apply the new calibration factors CAL_IA, CAL_VA, and PHADJ_A to the meter. The memory
locations for these factors are given in section 1.9.1.
Test the meter at nominal current and, if desired, at lower and higher currents and various phase
angles to confirm the desired accuracy.
Store the new calibration factors CAL_IA, CAL_VA, and PHADJ_A in the flash memory of the
meter. If the calibration is performed on a TERIDIAN Demo Board, the methods shown in sections
1.9.3 and 1.9.3 can be used.
For added temperature compensation, read the value in CE RAM location 0x54 and write it to CE
RAM location 0x11. If Demo Code 3.05 or later is used, this will automatically calculate the
correction coefficients PPMC and PPMC2 from the nominal temperature entered in CE location
0x11 and from the characterization data contained in the on-chip fuses.
2.2.3 CALIBRATION SPREADSHEETS
Calibration spreadsheets are available from TERIDIAN Semiconductor. They are also included in the CD-
ROM shipped with any Demo Kit. Figure 2-3 shows the spreadsheet for three measurements with three
phases in use (only one phase needs to be used for the 71M6511/6511H chip).
Figure 2-3 shows the spreadsheet for five measurements with three phases (only one phase needs to be
used for the 71M6511/6511H chip).
