Connect Interface PO2ES-103P Sensor 0...25 %VolO
Measurement range: 0...25 %VolO
Supply voltage: 18-36V DC
Analog output signal: 4-20mA (max. Shunt: 10 Ohm @ 18V; ~500 Ohm @ 36V)
 Measurement of sensor voltage (0...50 mV) with 15 bit resolution
 If the LED light flickers, the sensor voltage is outside of the measurement range
 Manuel calibration via button (jumper setting "Hand") :
a. Press the button HANDKAL for minimum 5 seconds => LED flashes
b. After 1 minute of stabilization time the sensor voltage are set to be equal to 20,95 %VolO2
c. A manual correction of the output signal can be made using the Potentiometer ("Verst.").
It is possible to adjust the output signal +/- ~2 mA @ 20 mA.
 Auto­calibration (jumper setting "Auto"):
a. The sensor voltage is measured continuously over a time period of 7 days, and the maximum
sensor voltage are stored. The stored value is after 7 days set to be equal to 20,95 %VolO
after which a new 7 day period start. In this way sensor drift is corrected.
At "Messpunkt (MP)" the output signal in voltage (0,4 Vto 2,0 V) can be measured.
