I am about to start testing some current sources. Output varies between -1000 mA and +1000 mA. Voltages involved: -5V / +5V.
I will use an analog multimeter. To make it simpler and avoid damages (wrong polarity), I considered using a diode bridge.
I need this not to be fast nor extremely precise, just to allow appreciating if for equivalent control voltages (measured with a DMM) the absolute value of the currents is in the ballpark.
Not sure if the use of diodes requires kind of spectial additional precautions.
Gracias for any suggestions.
