ADJUSTMENT
●Current detection circuit
Amplify and rectify potential differences at
two points in the primary-side current circuit
and send it to the AD-port of the MPU and
obtain data for displaying current value.
●Constant current output circuit
Remove troubles caused by the potential
differences between the constant current
output and the GND, so that the GND po-
tential differences between the H/U and the
AMP is not overlapped in the AMP to H/U
communication.
●I2C buffer
Using an IC for I2C communication, be-
tween-AMP communication is conducted so
that there will be no trouble from GND po-
tential differences.

CAUTION: Forcontinued safety,
replace safety critical compo-
nents only with manufacturer’s
recommended parts (refer to
parts list).
Indicates safety critical com-
ponents. To reduce the risk of
electric shock, leakage-current
or resistance measurements
shall be carried out (exposed
parts are acceptably insulated
from the supply circuit) before
the appliance is returned to the
customer.
•DC voltages are as measured
with a high impedance volt-
meter. Values may vary
slightly due to variations be-
tween individual instruments
or/and units.
