When the device is in current measurement mode, the input impedance is 10 . Therefore voltage input should not be connected to the device while
in current mode. Otherwise the device will deteriorate. If it is necessary to switch from the voltage measurement mode to the current measurement
mode while the device is running, It must be removed and then changed to one of the input type current measurement modes.
