Usage Notes
HIOKI LR8512B980-07
WARNING
• This instrument measures live wires. To avoid electric shocks when
measuring live wires, wear appropriate protective gear, such as
insulated rubber gloves, boots and a safety helmet.
• To avoid electric shocks, disconnect the clamp from the object to be
measured, open the cover, and then replace the batteries.
• After battery replacement, reattach and screw down the battery
cover before use.
• To avoid electric shocks, do not approach high-voltage equipment
or wiring when measuring the Class B ground cable for a
transformer. When the ground cable is close to a high-voltage live
partanditisdiculttomeasure,changetherouteoftheground
cable before measurement. (When the 9657-10, 9675 Clamp On Leak
Sensor is used)
CAUTION
• To prevent damage to the BNC connector, make
sure to release the lock and then pull on the
connector end of the BNC connector.
• Close the clamp core when it is not used. When the clamp core remains
open, dust collects on the butt joint of the core, which can cause a
malfunction.
• If the screw of the output terminal for the 9695-02 Clamp On Sensor is
lost, purchase the “M3 screw with spring washer × 5”. Using any screw
other than the above can cause damage to the clamp sensor.

HIOKI LR8512B980-07
CAUTION
• Do not excessively tighten the screw of the output terminal for the 969502 Clamp On Sensor. The appropriate torque is 0.5 N•m.
• Do not input current exceeding the specied measurement range. Doing
so may damage the instrument.
• Avoid stepping on or pinching the cords to prevent damage to them. Do
not bend or pull the cord bases.
• Do not drop or hit the clamp sensor. Doing so can damage the core butt
joint and negatively aect measurement.
• Do not tuck foreign material into the joint of the clamp core tip and
instrument or insert an object into the gap of the core. Doing so may
deteriorate the sensor characteristics or cause an open/close operation
failure.
• To avoid damaging the instrument, do not connect any equipment other
than the clamp sensor to the BNC terminal.
• To avoid damaging the instrument, do not short the connector or input
voltage.
• When dust is attached to the clamp core tip butt joint, gently wipe it with a soft
cloth to prevent adverse eects on measurement.
• When connecting a cable to the output terminal of the 9695-02 Clamp On
Sensor, bring the cable as close to the terminal as possible to avoid the inuence
of an external magnetic eld.
• When connecting the 9695-02 Clamp On Sensor to the instrument, use the 9219
Connection Cable. (The 9219 connection is “Crimped terminal-BNC”.)

Handling of temperature and humidity sensor
CAUTION
• The temperature and humidity sensor is not dustproof or waterproof. Do
not use the sensor in locations where it may be exposed to dust or water.
It may cause a malfunction of the instrument.
• The temperature and humidity sensor is not drip-proof. Water that drips
onto the connector could cause a malfunction.
• Sensor sensitivity and precision will degrade over time, even under normal
operating conditions. To maintain the instrument’s ability to make measurements
that conform to the accuracy specications, it is recommended to replace the
temperature and humidity sensor with a new unit once it has been used for one
year after being opened.
• When the sensor is used outside the specied operating (storage) environment,
the sensor accuracy may deteriorate even within the 1 year accuracy warranty
period and accurate measurement cannot be performed.
• In principle, the surface of the instrument’s temperature and humidity sensor
may become contaminated if exposed to an environment containing organic
gases (ketone, acetone, ethanol, toluene, etc.), increasing the error component
of humidity measurement.
• Do not expose the temperature and humidity sensor to any concentrated
chemical solvent for an extended period of time while it is used or stored.
• The sensor may become contaminated by organic gases released from some
types of vinyl chloride and packaging material.
• When the temperature and humidity sensor is not used, place it with a drying
agent in a plastic bag, seal the bag completely, and store it in a cool, dark place.
• Do not allow any condensation to form. Condensation can form particularly in
any environment where the temperature changes drastically.
• This instrument does not come with a guarantee against any problem when the
sensor is used outside the specied operating (storage) environment.
• Due to a humidity change (from low to high humidity or high to low humidity),
up to ±1% RH of change (hysteresis) occurs in the measured humidity value.
