*1 Programmable controllers are open-type devices (devices designed to be housed inside
other equipment) and must be installed inside a conductive control panel. The tests were
conducted with the programmable controller installed in a control panel.
*2 The accuracy of an analog-digital converter module may temporary vary within ±10%.
