Pre-use inspection
Inspect the instrument and wireless module before turning them on to check for damage during
storage or shipping.
If you nd any damage, contact your authorized Hioki distributor or reseller.
Inspection of peripheral equipment
Do the measurement cables you’re about to connect have tears in their insulation, or is any metal
exposed?
If you nd any damage, do not use the measurement cable. Doing so could cause electric shock.
Replace the cable with the designated type.
Inspection of the instrument
• Does the instrument exhibit any damage?
If you nd any damage, have the instrument repaired.
• When you turn on the instrument, does the screen work?
If no screen is displayed, there may be a wiring break in the power cord, or the instrument may
be damaged. Have it repaired.
Handling of cords and cables
WARNING
Ensure measurement cables hang lower than the instrument.
Failure to do could allow water or other liquids to travel down the measurement
cables into the instrument, resulting in damage or bodily injury.
Before connecting measurement cables to measurement terminals or
turning on the instrument, follow the procedure below:
1. Shut o the power to the measurement lines.
2. Turn o all equipment.
3. Remove the measurement cables from measurement targets.
4. Close the terminal block cover.
Use specied wiring only. Alternatively, use wiring that provides
sucient dielectric strength and current capacity.
Failure to do so may result in electric shock or a short-circuit.
Surely connect measurement cables to the input terminals.
A loosened screw could cause contact resistance to increase and thus the instrument
to overheat, resulting in bodily injury, burning of the instrument, or re.
CAUTION
Do not step on cords or allow them to become caught between other objects.
Doing so may damage insulation, resulting in bodily injury.
