5.8 Coupon Disconnect
The internal coupon to pipe connection relay may be manually placed into a disconnect state for single coupon
measurement types. Place a magnet over the test switch area for a duration longer than 5s to initiate this function. The
LCD display will then show that the coupon relay has opened; in addition to the open switch symbol, the reading area
will display ‘- [ ] -‘ while the function is enabled. Re-apply the magnet to the test switch for an additional 5s to reconnect
the coupon relay. The coupon relay will also automatically reconnect at the next wakeup interval of the RMU1.
The coupon disconnect cannot be toggled if the RMU1 is currently performing a depolarization cycle. Note also that
this function is only operational if the “Enable Depolarization” option is enabled in the unit configuration.
