*1 QP: Quasi-peak value, Mean : Average value
*2 The GOT is an open type device (device installed to another device) and
must be installed in a conductive control panel.
The above test items are conducted in the condition where the GOT is
installed on the conductive control panel and combined with the Mitsubishi
PLC.
