To cut and calibrate yoursender you’ll need:• PFS or PTS sender• LLM-1 or LLM-2 series
display
And the following tools:• 5-gallon bucket or tank• Fine tooth hack saw• Measuring tape• Razor knife or box
cutter• Masking tape
Factory calibrated senders are available in one inch increments from 7” to
36” in length. All Xintex senders are field calibrated. To cut and calibrate
your own Xintex sender, follow the instructions below.

Step 1: Measure your holding tank
![Page 4: Cutting & Calibrating Your Xintex Pneumatic Tank Sender](https://reader031.vdocuments.us/reader031/viewer/2022012512/618bbfe49f578a1a5d2c17e6/html5/thumbnails/4.jpg)
Step 2: Determine the desired length for your sender by subtracting 1.5” from the depth of your tank (from the top of threads or to flange)
and then rounding down
Sender Length = Depth of tank ie. 24.0”
Minus - 1.5”
22.5”
Rounded down = 22 inch sender

Step 3:Score the surface of your sender to mark the cutting line
(or mark with masking tape as shown above)

Step 4: Carefully cut the sender using a fine-tooth, hand held saw
(Secure tightly to avoid damaging vibrations)

Step 5: Snap the sender to complete the break

Step 6: Using a razor knife or box cutter,
smooth any rough edges

Step 7: After connecting the sender to the display begin the calibration process by marking the sender, determining the
“empty” setting

Step 8: Next, mark the sender at the “full” point*
* (Factory recommendation is 2” from the top of sender)

Step 9: Remove the pre-stripped sheathing from the green and
white wires and touch them together, or use a wire nut.

Step 10: Submerge the sender to the level at which you want the
display to read “empty”
![Page 13: Cutting & Calibrating Your Xintex Pneumatic Tank Sender](https://reader031.vdocuments.us/reader031/viewer/2022012512/618bbfe49f578a1a5d2c17e6/html5/thumbnails/13.jpg)
Step 11: Connect the red and black wires from the display to a
12V source and wait 30 seconds.

Step 12: Submerge the sender to the level at which you want the display to read “full” (factory setting is 2” from the top of the
sender)
![Page 15: Cutting & Calibrating Your Xintex Pneumatic Tank Sender](https://reader031.vdocuments.us/reader031/viewer/2022012512/618bbfe49f578a1a5d2c17e6/html5/thumbnails/15.jpg)
Step 13: Disconnect the green and white wires and wait 30
seconds. Remove power. The unit is now calibrated.

Step 14: Snip the exposed green and white wires back to avoid accidental entry into calibration mode. Empty, half and full
level displays shown above.*
*There is a 10-second delay for software updates
between level readings
