Finishing step Check if the cables are connected properly (have you
connected all the cables; have you connected them to the
right place; is the connection stable; do not the cable-ends
touch each other).
Checking the connection After the connections have been made, put the
measurement loop (the measuring transformer) under
voltage, if possible.
If the connection is perfect, some numbers or a text appear
on the display.
If nothing appears on the display, most probably the
apparatus does not get supply power. With a voltage meter
instrument check if there is voltage bI and -I
connection points. If the measurement shows that the
voltage value is higher than 12 V, then this error-possibility
can be excluded.
In the next step, you may suspect that the cables are
connected to the apparatus with reverse polarity (the two
wires of the cable are interchanged), or they are connected
not to the specified terminal-assembly points. Check if
everything has been done in accordance with chapter 5.1.
Connection to the measurement loop.
With this you have completed the connection of DT9502.
