Applying measurement current
The EM-PQ2500 is designed for the connection
of ../1A and ../5A current converters.
Only AC currents, and not DC currents, can be
measured using the current measurement in-
puts.
Short-circuit all current converter outputs ex-
cept one. Compare the currents displayed by
the EM-PQ2500 with the applied current.
The current displayed by the EM-PQ2500 must
match the input current under consideration of
the current converter transfer relation.
The EM-PQ2500 must display approx. zero
amperes in the short-circuited current measu-
rement inputs.
The current converter ratio is set to 5/5A in the
factory and may have to be adapted to the cur-
rent converter used.
Warning!
Voltages and currents outside of the
authorized measurement range can
destroy the device.

Voltages are shown with long pointers in the
pointer diagram, and currents with shorter
