PART 1 - TFXP TRANSMITTER CONNECTIONS
After unpacking, it is recommended to save the shipping carton and
packing materials in case the instrument is stored or reshipped.
Inspect the equipment and carton for damage. If there is evidence
of shipping damage, notify the carrier immediately.
When the TFXP is to be utilized for extended periods of time in one
location, the enclosure should be placed in an area that is
convenient for servicing, calibration or for observation of the LCD
readout.
1. Locate the transmitter within the length of transducer cable that
was supplied with the TFXP system. If this is not possible, it is
recommended that the cable be exchanged for one that is of
proper length.
NOTE: The transducer cable carries low level, high frequency
signals. In general, it is not recommended to add additional cable to
the cable supplied with the DTTN, DTTH, DTTS or DTTC
transducers. If additional cable is required, contact the Dynasonics
factory to arrange an exchange for a transducer with the appropriate
length of cable. Cables to 990 feet (300 meters) are available. If
additional cable and connections are added, ensure that they
are RG59 75 Ohm compatible.
2. Place the TFXP transmitter in a location that is:
• Where little vibration exists.
• Protected from corrosive fluids.
• Within ambient temperature limits -40 to 185 °F (-40 to 85 °C).
• Out of direct sunlight. Direct sunlight may increase transmitter
temperature to above maximum limit and make viewing the
LCD difficult.
3. If the transmitter will be subjected to a wet environment, it is
recommended that the cover remain closed and the latches
secured after configuration is completed. The faceplate/keypad
of the TFXP is watertight, but avoid letting water collect on the
keypad area.
