WARNING
• When connecting a device under measurement to the instrument, be sure to turn off the
device. It is extremely dangerous to connect or disconnect wires while the device under
measurement is on.
Precautions to Be Taken When Using the Modules
• 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 protection function and the mechanical protection function will not be
activated.
Precautions to Be Taken When Using the 16-CH Scanner Box
• Do not connect or disconnect the 16-CH scanner box or the cables that are connected to it
while the power is on.
• Do not apply input voltage exceeding the maximum input voltage, withstand voltage, or
allowable surge voltage.
• 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.
• Applying a voltage exceeding the value indicated below may damage the input section.
If the frequency is above 1 kHz, damage may occur even when the voltage is below this
value.
Maximum input voltage (across the input terminals, + and −,
1
at a frequency of 1 kHz or
less)
42 V (DC + ACpeak)
Maximum allowable common
mode voltage (across the input terminals, + or −, and earth,
2
at a frequency of 1 kHz or less)
42 V (DC + ACpeak) (CAT II, 30 Vrms)
• The − input terminals of the sub channels are electrically insulated inside the scanner
box. If you connect a wire that has a potential difference greater than 42 V (DC + ACpeak)
between sub channels, the insulation may be damaged, which will lead to the 16-CH
scanner box being damaged.
