VREF pin - LEM HLSR Series Current Sensor

[DHARITRI HAZARIKA]

Hello Everyone,

I am new to the LEM HLSR series current sensor series. If anyone have used or knows about the sensor can you please help me in below point.:4

The LEM HLSR 10-p series can measure current of +-25A, with an output voltage of +-2V, But in the datasheet of the HLSR 10-P, there is one pin VREF, for overdriving the current measurement capability of the sensor. I don't need this feature, so can anyone suggest what to do with the VREF pin, should I leave it floating ?


Thanks & Regards,
Dharitri Hazarika

Looks like Vref is a 'requirement' whether you want it or not as it is used to calibrate the output.

Suitable volt-drop resistor combination across the supply line and with a multi-turn preset to set.
