AD737 circuit


i bought this chip for our lab. we need to measure the current rms value of a certian device in our experiment.

we plan to use CT and measure the rms voltage on a shunt resistor.

i tried to simulated the DVM circuit from the data.

but when i probe the output pin i get increasing of the voltage...

i attached picture of the circuit and the file of the simulation.

please help me with that...

thanks and best wishes,
