1/3
In the current measurement mode input impedance is 5
Therefore, in the current measurement mode, a voltage input
should not be connected to the input terminals, otherwise, the device will be damaged.
W.
To change the input type from
voltage to a current measurement mode, isolate the input before changing the operation mode.
EI141 must not be used in location where measurement category is II, III or IV.
