how to display pulsating current on DPM

I made a current source(upto 10 A) which is used for magnetic field generation. This current source is working on 1 hz pulse triggering i.e. ON for 1 sec and OFF for 1 sec. cu

Now i have to display the current through DPM. But it is showing variating current. I have used 0.1 ohm resistance for sensing current which is giving voltage of 0.1V for 1A and so on. this voltage is too low so i have used precision amplifier than RC circuit to show constant display on DPM. but it is not working as i wish.
I used a

Well can you send a schematic of the circuit and scope waveform, even if you have to use your phone camera to take a shot (it works, done it many times).

Then we can figure it out.

Could the problem be the sampling rate of the DPM ?
It may be taking samples at different points on the waveform each time.
The window of time during which it samples the waveform ?
The rate at which the sampled voltage decays until the next sample ?

(PS: your message appears to be cut off in the middle of a sentence.)

(And as Earl says, always post your circuit diagram and oscilloscope trace.)

Need a circuit and ideally you want sample and hold funtionality as Frank says this could be sampling in tge incorrect place on the output so you may need to convert to dc first Im assuming your dealing with ac signal across load So you may also want peak detector to act as trigger source so as to attain max current at peak amplitude holding this value untill next trigger pulse

1 sec on and 1 sec off is 0.5Hz, not 1Hz

Yes, but maybe 1Hz input pulses are being used to trigger the current alternately on and off, thus giving 0.5Hz output. Happy Christmas everyone.

And Merry New Year!
