WARNING
• When connecting a device under measurement to the instrument, be sure to turn off the
device. It is extremely dangerous to connect or remove wires while the device under
measurement is on.
Avoid Electric Shock When Using the Modules
• Do not apply a voltage that exceeds the maximum input voltage, withstand voltage, or
allowable surge voltage.
• To avoid electric shock, be sure to ground the instrument.
• To prevent the possibility of electric shock, be sure to fasten the module screws. Otherwise,
the electrical and mechanical protection functions will not be activated.
• Do not leave the instrument connected to devices in an environment that may be subject to
voltage surges.
• To prevent electric shock, connect wires to the terminal block that match the voltage range
that you are measuring.
