Calibration:
After cutting, make sure the sensor tube is clean.
Re-plug the Filter footer and tighten the screw.
PLEASE FOLLOW THESE STEPS IN ORDER:
GET ZERO (4mA): After cutting, clean the probe, put the probe in the media at expected
level near the bottom or leave the probe at dry condition, press CALIB button in 0.2 - 3
seconds, the LED will always ON in this press time.=> ZERO is achieved, output current =
4mA.
GET SPAN (20mA): Put the probe in the media to the expected upper level then press
CALIB button in 3-6 seconds, the LED will ON then OFF.=> SPAN is achieved, output
current = 20mA. In 30 seconds without pressing the CALIB button, the sensor will turn
back to OPERATION mode.

Final:
Place the O-ring on the top of the threads, ensure that it can touch the aluminum housing of the
sensor (as below picture):
Install sensor into the threads of flange and turn it in clockwise direction.
Using the O-ring enables to rotate the sensor within 180 degrees from final tighten position and
assuring that the oil will be not spilled (as below picture):
Use the 2mm Allen key to lock the hex bolt to protect the sensor rotate backwards.
Connect the sensor with the cable.
Use sensor head seal to cover the sensor and then use plastic and then use plastic twister seal
to lock the head seal and connector seal to protect the sensor.
Please follow the below steps:
Note
Step 1: Remove the cover
Step 2: Remove the terminal connector
Step 3: Use the 2 mm Allen key to unlock the hex bolt
Step 4: Turn the sensor in counter-clockwise direction
Do not hold the male connector to rotate sensor
directly, that can make the male connector broken.
Do not use locking pliers, pipe wrenches, etc. to
twist the sensor as this cause damages the
structure of the sensor such as cast aluminium
housing, label, signal cables (connector), circuit
board, ect. and it will not be covered under
warranty.
