Safety Information
Safety Information
Before using the device, be certain to carefully read the following safety notes.
DANGER
Mishandling during use could result in injury or death, as well as damage to the
device. Be certain that you understand the instructions and precautions in the
manual before use.
WARNING
•With regard to the electricity supply, there are risks of an electric shock,
heat generation, re, and arc ash due to a short-circuit. Individuals using
an electrical measuring device for the rst time should be supervised by a
technician who has experience in electrical measurement.
•Protective gear
This device is measured on a live line. To prevent an electric shock, use
appropriate protective insulation and adhere to applicable laws and regulations.
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the full benets of the various functions.
Checks before use
DANGER
If the connection cord or the device is damaged, there is a risk of an electric
shock. Perform the following inspection before using the device:
•Check that the coatings of the connection cords are neither ripped nor torn and
that no metal parts are exposed. Using the device under such conditions could
result in an electric shock. Replace the connection cords with those specied
by our company.
•Verify that the device operates normally to ensure that no damage occurred
during storage or shipping. If you nd any damage, contact your authorized
Hioki distributor or reseller.
WARNING
To prevent an electric shock, conrm that the white or red portion (insulation
layer) inside the cable is not exposed. If a color inside the cable is exposed, do
not use the cable.

Operating Precautions
Installing the device
WARNING
•Ventilation holes for heat radiation are provided on the side and rear panels of
the device. Leave sufcient space around the ventilation holes and install the
device with the holes unobstructed. Installation of the device with the ventilation
holes obstructed may cause a malfunction or a re.
•Unplugging the power cord kills power to the device. Be sure to provide enough
unobstructed space to unplug the power cord immediately in an emergency.
Installing the device in inappropriate locations may cause a malfunction of device
or may give rise to an accident. Avoid the following locations:
•Exposed to direct sunlight or high temperature
•Exposed to corrosive or combustible gases
•Exposed to a strong electromagnetic eld or electrostatic charge
•Near induction heating systems (such as high-frequency induction heating
systems and IH cooking equipment)
•Susceptible to vibration
•Exposed to water, oil, chemicals, or solvents
•Exposed to high humidity or condensation
•Exposed to high quantities of dust particles
CAUTION
Failure to observe the following precaution may result in bodily injury.
•The device weighs approx. 47 kg (Model SM7860-57 and SM7860-67: approx. 34 kg).
It should be moved by at least two people, who should grip it using the handles on the
left and right sides. The center of gravity is located on the front side of the device.
•The device is heavy. When transporting it, follow your company’s workplace safety
standards to assure safety (for example, by wearing non-slip gloves and protective
footwear).
Do not place the device on an unstable table or inclined place. Dropping or knocking
down the device can cause injury or damage to the device.

6
Operating Precautions
Installing
Prolonged operation in hot temperatures will shorten the device’s service life. Keep the ambient temperature
as low as possible.
•Avoid obstructing the ventilation holes.
• To prevent overheating, be sure to leave the specied clearances around the device.
•When rack-mounting the device, fans must be installed above or on top of the rack to ensure proper
ventilation. Be sure that the rack is adequately ventilated so that the internal temperature remains at or
below 40°C.

Handling the Device
DANGER
•Do not use the device with circuits that exceed its ratings or specications.
Doing so may damage the device or cause it to become hot, resulting in a bodily
injury.
•Do not short-circuit two wires to be measured by bringing the cable into contact
with them. Arcs or such grave accidents are likely to occur.
CAUTION
Failure to observe the following precaution may result in bodily injury.
•The device weighs approx. 47 kg (Model SM7860-57 and SM7860-67: approx. 34 kg).
It should be moved by at least two people, who should grip it using the handles on the
