The MRX SG Marker locator should be regularly checked to ensure its correct operation.
eCert provides a thorough test of the MRX SG Marker’s locating circuitry and marker transceiver and supplies a Radiodetection Calibration Certificate when a positive test result is obtained.

To run eCert, the locator should be connected to an internet-enabled PC, on which the RD Manager Online software is installed. Additional eCert credits may be required and purchased.
Refer to the RD Manager Online operation manual for further details.

NOTE: eCert is not presently available for transmitters.
