Overcurrent protection



  • Hello all,

    I am using the potentiostat to measure the current from a photoelectrochemical cell at a constant voltage. The current that I will obtain may vary according to the samples (anodes) I use and over time. I am worried it might get above 100uA. Should I connect a resistor and if so, How would be the best way? to protect my computer and the potentiostat.

    Thanks in advance

    This is with the Rodeostat correct? Going over 100uA shouldn't be an issue. There are four current ragnes +/- 1, 10, 100 and 1000 uA. So ideally you would use the 1000uA current range setting? But even in the +/-1, 10, and 100uA ranges going over 100uA should not cause any damage to the potentiostat or the computer. Your current measure will clip at the limits of the range, but otherwise it should be fine . If you think it might have more than a couple of mA then you might want to take measures to limit the current.
