Recommend to use 24VDC power.
The signal cable from sensor should be protected by corrugated hose or the Φ16 plastic tube, keep the cable avoid
high temperature areas.
Depending on the type of oil tank, we have different calibration of the corresponding oil quantity. Refer to the excel file
below to calculate the volume
PulseCAP10 with 4-20mA Output has an advanced feature is Field Calibration. Field Calibration allows customers to
calibrate the sensor after cutting. It will works with many non-conductive media such as Vegetable Oil, Non-standard
Diesel, Light Fuel Oil... To enter Calibration Mode: press the CALIB button on top housing 3 times, time interval
between press not greater than 1.5 seconds. LED will blinked at 5Hz in Calibration mode.
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.

11.2 Calibration 4-20mA
It is recommended to use a PVC plastic tube and oil to calibrate the 4-20mA before inserting into
the oil tank
