instrument operation by use of a volt free link, switch or relay. The instrument can be
configured to initiate the appropriate action when the contact either closes or opens.

SD Card Interface
The MXD73 features a SD card interface which is compatible with SD, SDHC and SDXC
formatted cards (N.B. SDXC cards may need formatting by the MXD73 before use – see user
interface guide). The card can be removed whilst the instrument is on but only when the
disk icon is not shown at the top of the display.
To insert the card ensure that the corner notch is on the top right of the card, and then just
push it all the way in to the socket. To remove the card push it in then release and the card
should then come out of the socket. N.B. It may be required to pull the card out of the last
bit of the socket.
