Usage Notes
Handling the device
This device may cause interference if used in residential areas. Such use must be avoided unless
the user takes special measures to reduce electromagnetic emissions to prevent interference to the
reception of radio and television broadcasts.
Before installing the module
WARNING
• To prevent an electric shock, before removing or replacing a module, confirm
that the device is turned off and that all the measurement cables, connection
cables, and the power cord are disconnected.
•
Installing a module while the device is turned on may prevent detection of
the contact state of relays on the module or result in short-circuiting of the
measuring object. Damage of the device or module may cause the measuring
object to be shorted or the instrument to fail.
•
Be careful about short circuits when connecting a measuring object with
electromotive force (battery, power supply, etc.).
•
The maximum voltage of the device contact is 30 V (rms value) and 42.4 V (peak
value) or 60 V (direct current). Do not directly connect a withstand voltage tester
or an insulation resistance tester.
CAUTION
When installing or removing the module, be sure to observe the following precautions:
• Touch the GND terminal of the device with your hand to release static and then use
antistatic gloves to perform procedures.
• Hold the sheet metal area of the module. Directly touching the board with your hand may
damage the circuit board due to static. If the measurement target has high resistance, the
error component due to factors such as oil from your fingers may increase in magnitude.
Before measurement
DANGER
• Do not short-circuit between electrodes or terminals using a probe when
measuring the battery or capacitor. Doing so may cause an electric arc, resulting
in serious injury.
• Do not use the device or the connection cables that exceed its ratings or
specifications. Doing so may damage the device or cause it to become hot,
resulting in a bodily injury.
• Do not use the instrument to be used in conjunction with the device outside of
its ratings or specifications. Doing so may damage the instrument or cause it to
become hot, resulting in a physical injury.
WARNING
The maximum rated voltage between the module and ground is 60 V DC. To avoid
an injury and damage to the device, ensure that voltage between channels never
exceeds this limit. Prevent the voltage potential difference of the entire system
from exceeding 60 V DC.
The measurement connector frame of the module is connected to the casing (metal) of the device
as well as the protective ground terminal of the power inlet (conductive).
