Operating Precautions
Wiring
DANGER
• Do not short-circuit two wires to be measured by bringing the metal part of the
voltage cord clips or current sensor tips into contact with them. Doing so could
result in a severe accident such as arcing.
• To prevent electrical shock and personal injury, do not touch any input terminals
on the VT (PT), CT or the instrument when they are in operation.
• Do not use the instrument with circuits that exceed its ratings or specications.
Doing so may damage the instrument or cause it to become hot, resulting in
bodily injury.
• To avoid electric shock, be careful to avoid shorting live lines with the voltage
cords.
• We recommend measurements at the secondary side of the distribution
panel. Measurements at the primary side cause unrestricted current ow. The
instrument and equipment could be damaged if a short circuit occurs.
• To avoid short circuit or electric shock, do not touch the metal parts of the
voltage cords or current sensor tips.
CAUTION
• To avoid damaging the instrument, do not short the voltage cord input terminals or
current sensor input terminals or input any voltage to them.
• To ensure safe operation, use only the voltage cord and current sensor specied by
Hioki.
Displayed values can frequently uctuate due to induction potential even when no voltage is applied. This,
however, is not a malfunction.
Using USB Connector (USB Cable)
CAUTION
• To avoid equipment failure, do not disconnect the USB cable while communications are
in progress.
• Use a common ground for both the instrument and the computer. Using different ground
circuits will result in a potential difference between the instrument’s ground and the
computer’s ground. If the USB cable is connected while such a potential difference
exists, it may result in equipment malfunction or failure.
• If the instrument and computer are both off and connected with the USB cable, turn on the computer and
then the instrument. Powering up the devices in a different order may prevent the instrument and computer
from communicating.
• Copying large data les from the SD memory card to a computer via the instrument’s USB interface can be
time-consuming. When you need to copy a large data le to a computer, it is recommended to use an SD
memory card reader.
