REPLACEMENT RTDS
If it is necessary to replace RTDs, complete RTD kits including the energy meter’s plug-in connector and calibration values for
the replacements are available from the manufacturer.
It is also possible to use other manufacturer’s RTDs. The RTDs must be 1000 Ohm platinum RTDs suitable for a three-wire
connection. A connection adapter, P.N. D005-0350-300, is available to facilitate connection to the energy version.
See Figure 37 .
