Functions and performances:@23°C ±5°C
Accuracies are given in % of reading(a CALYS 50 display) + fixed value
Direct current: Measurement
Calys 50 is able to measure up to 50 mA, with or
without power supply of loop (24V power supply).

For measurements of transmitters outputs, special
ranges give a dual display using mA and % of full
scale.
Calys 50 also allows to linearize following linear or
quadratic signal.
In current measurement Hart compatibility can
selected to measure currents coming from Hart
protocol transmitters
