Appendix D: Field Sensor Replacement

The 717 uses field replaceable smart sensors. When you receive a sensor it
will come pre-calibrated. Factory calibration once per year is still important to
ensure your analyzer is functioning properly on all functions and ranges.

Contact your TPI distributor to purchase replacement sensors.

Note: You must wait 24 hours after sensor replacement before using your
analzyer.

Follow these steps to replace the sensors:

1. Remove the protective rubber boot by using your hands to pry the boot from

the bottom of the analyzer first. Once the bottom is free the boot can be
removed.

2. Locate the screw that secures the sensor access panel to the back of the ana-

lyzer. The screw is located just above the battery access screw. (see picture
below)

3. Loosen the screw and remove the access panel by lifting the end by the

screw up first.
