AC Current monitoring sensor - Calibration

Products
1

Hi,

I am using AC Current monitoring sensor. I wish to read current of range 0 - 100mA. Current coil used is OPCT16AL 10(100)A/5mA. What can be the calibration value to achieve my range. Now I am getting 0 mA data frame.

Thanks in advance.

the minimum current this sensor ca read is 1.5Amp
if you want to read below 1.5Amp i will suggest

  1. warp the wire around the CT ( lets say 5 times)
  2. read the current value and divide them by 5 and you will get actual current

or
we can build a custom current sensor which can read low current
