Resistance values shown in the tables below are for measurements taken with the cables
disconnected from the Metering Unit. This method is more effective in identifying internal damage in
the Measuring Head and cables that might occur during shipment.

NOTE:
•
All resistances are measured by lifting cable leads at the Metering Unit and connecting ohmmeter
between designated cable conductors. For Metering Units with two cables, each cable is measured
separately.
•
These resistance readings are the room temperature values of the copper channel coils. Measured
values can be 50% higher if head is hot and/or cable length is longer than 30 feet.
