2.4 TESTING THE DEMO BOARD
This section will explain how the 71M6543F IC and the peripherals can be tested. Hints given in this section will
help evaluating the features of the Demo Board and understanding the IC and its peripherals.
Demo Board. It interfaces to a PC through a 9 pin serial port connector.
It is recommended to set up the demo board with no live AC voltage connected, and to
connect live AC voltages only after the user is familiar with the demo system.
BEFORE CONNECTING THE DEMO BOARD TO A CALIBRATION SYSTEM OR OTHER
HIGH-VOLTAGE SOURCE IT IS RECOMMENDED TO MEASURE THE RESISTANCE BE-
TWEEN THE LINE AND THE NEUTRAL TERMINALS OF THE DEMO BOARD WITH A MULTI-
METER. ANY RESISTANCE BELOW THE 1 M Ω RANGE INDICATES A AFAULTY CONNEC-
TION RESULTING INDESTRUCTION OF THE 71M6543.
2.4.1 FUNCTIONAL METER TEST
This is the test that every Demo Board has to pass before being integrated into a Demo Kit. Before going into
the functional meter test, the Demo Board has already passed a series of bench-top tests, but the functional
meter test is the first test that applies realistic high voltages (and current signals from current transformers) to
the Demo Board.
Figure 2-8 shows a meter connected to a typical calibration system. The calibrator supplies calibrated voltage
and current signals to the meter. It should be noted that the current flows through the shunts or CTs that are not
part of the Demo Board. The Demo Board rather receives the voltage output signals from the current sensor. An
optical pickup senses the pulses emitted by the meter and reports them to the calibrator. Some calibration sys-
tems have electrical pickups. The calibrator measures the time between the pulses and compares it to the ex-
pected time, based on the meter Kh and the applied power.
