Read the following safety information. (continued)
CAUTION

Hold the plug when removing the AC adaptor (option) from the
outlet.
Pulling on the AC adaptor cable will damage the cable. This may be a cause
of an electric shock, fire, or failure.

Do not expose to rapidly-changing temperature, mechanical
stress, or impact.
The main unit, coil, sensor, BNC cable and AC adaptor will be damaged if
exposed to these. This will be a cause of a failure.

Do not use or store this instrument in a location with direct
sunlight, high temperature, high humidity, or dew condensation.
Operation or storage outside the ratings could result in deformation,
deteriorated insulation, or a failure due to heat. The ranges of operating and
storage temperature and humidity are as follows:
• Operating temperature: 0 to +40

C (coil part: − 40 to +125

C), no dew condensation
• Operating humidity: below the moisture amount of 80%RH
• Operating altitude: 2000 m or less (at 25

C or less)
• Storage temperature: − 10 to +60

C, no dew condensation
• Storage humidity: below the moisture amount of 80%RH

Do not place this instrument in a location with excessive
humidity or dust.
If not, an electric shock, fire, or failure may occur.

Do not put this instrument in a place exposed to lamp soot or
steam generated by counters, humidifiers, etc.
If not, an electric shock, fire, or failure may occur.

Avoid pulling or bending the Rogowski Coil Sensor part with
excessive force as much as possible. The Rogowski Coil has a coil
structure consisting of an extra-fine wire rod wound tight.
Pulling or bending the Rogowski Coil Sensor part with excessive force may
degrade the specifications of the sensor part due to the change of the coil
structure.

When adjusting the DC offset voltage (zero point), use the
included accessory Adjustment Screwdriver, align the tip of the
screwdriver with the adjustment slot, and turn it without applying
excessive pressure. The required rotation torque is less than 20
mN
･
m.
If using a screwdriver other than the accessories or applying excessive
pressure to ZERO ADJ of the main unit while you don’t align the included
accessory Adjustment Screwdriver with the adjustment slot, you may damage
the main unit or the tip of the screwdriver.

For your safety, when this instrument is not used for a long time,
turn the POWER switch to the O side to turn off the power to this
instrument, and then remove the batteries from this instrument
(remove the AC adaptor from the outlet when used).
