A $\text{1000/1 A, 5 VA, UPF}$ bar-primary measuring current transformer has $1000$ secondary turns. The current transformer exhibits a ratio error of $-0.1\%$ and a phase error of $3.438$ minutes when the primary current is $1000 A.$ At this operating condition, the rms value of the magnetization current of the current transformer $\text{(in amperes, rounded off to two decimal places)}$ is _________
