The gravity arduino turbidity sensor

Recently i bought this turbidity sensor https://wiki.dfrobot.com/Turbidity_sensor_SKU__SEN0189 and i have a question about this. This sensor has an output of 0-4.5 V but when i plug it in i only see 3.5V when i put the switch on A for analog wich is weird because i see the full 5v when i put it on D Digital. I can ge by with 1 volt less but now i put a resistor of 175 ohms in series with the analog output to convert 0-3.5V to 0-20mA and when i put the switch on A i get max 0-3ma but when i switch it back to D i get the full 0-20ma?? anyone know why this is happening
here is the wiring of the sensor itself maybe this will help https://iprototype.nl/docs/turbidity-sensor-schema.pdf
thanks in advance

2019-05-17 02:06:09 Analog output analog voltage value, corresponding to know the turbidity of water, potentiometer can be used as a calibration.
A digital quantity that is adjusted by a potentiometer to set the level position as the trigger.
Please calibrate before use.Two different reasons output different voltage values, may be more intuitive to see the schematic. techsupport
