Is it necessary to calibrate the probes during their usage?

  • No. The probes are calibrated in our production and should carry properties forever.

What is the accuracy of Powersense DC?

  • The declared precision is up to 2% from the nominal current (we offer 50A, 100A or 400A transducers), so for the 400A the effective precision is +-8A! So to measure low currents, with 400A is not a good set-up. Try to make the best estimation for your actual needs and choose the suitable transducers.
