2.4 Connection of remote meters
The G meter can be supplied as remote meter with 5 m cable. Under no circumstances should
the cable be cut shorter or joined to increase its length. The meter is calibrated with this 5m
length. Any changes will influence the performance of the meter.
There are two different configurations of remote meter, on the first version the cable is fixed at
the converter end and the second has a terminal junction box at the converter end.
