Jumper Configuration
Overview
Before programming the meter, it is necessary to configure three jumper arrays.
The jumper arrays are used for setting the type of input signal (4-20 mA, 0-5 V,
or 0-10 V); locking out the programmed settings, enable relay acknowledgement
(ACK), and setting relay fail-safe operation.
