Precautions

• Confirm battery remaining level before operating.
• Do not leave the instrument under strong sunlight for a long time. It may

cause the instrument to malfunction.

• When transporting the instrument, provide some protection to minimize the

risk of shocks. Heavy shocks may cause the measurement to be faulty.

• The instrument can not be submerged underwater. WT-100 is designed

based on the International Standard IP54, therefore it is protected from the
normal rainfall.

• Remove the battery from the instrument when you would not use it for long

period. If this instrument with the battery set in it is stored, the electrolyte may
leak to cause a trouble.

• Always clean the instrument after use. Wipe dry any moisture if the instrument

becomes wet from rain. To clean the instrument, dust off well and then wipe
clean with a soft cloth.

• Never use thinner or benzine to remove dust on the surface of plastic parts.

Use a clean cloth moistened with neutral detergent.

$

:

• Attach a ferrite clamp filter (ZCAT2035-0930 or equivalent) to the power cable

when using an external battery. 
Always wind the cable through the clamp filter in a single loop.
Do not remove the ferrite clamp filter from the cable. Removal of the ferrite 
clamp filter may cause harmful interference and will void the user’s authority 
to operate this equipment.

1. Turn on the power.

Press the power switch.

PRECAUTIONS FOR SAFE OPERATION

C

 WARNING

Ignoring this indication and making an operation error could
possibly result in death or serious injury to the operator.

C

 CAUTION

Ignoring this indication and making an operation error could
possibly result in minor injury or property damage.

J

This symbol indicates items for which caution (hazard warnings inclusive) is 
urged. Specific details are printed in or near the symbol.

D

This symbol indicates items which are prohibited. Specific details are printed in 
or near the symbol.

I

This symbol indicates items which must always be performed. Specific details 
are printed in or near the symbol.

PRECAUTIONS

D

Do not use the unit in areas exposed to high amounts of dust or ash, in areas 
where there is inadequate ventilation, or near combustible materials. An explo-
sion could occur.

G

Do not perform disassembly or rebuilding. Fire, electric shock, or burns could 
result.

D

Do not short circuit. Heat or ignition could result.

D

Do not place articles such as clothing on the battery charger while charging bat-
teries. Sparks could be induced, leading to fire.

D

Do not use voltage other than the specified power supply voltage. Fire or electri-
cal shock could result.

D

Do not use batteries other than those designated. An explosion could occur, or 
abnormal heat generated, leading to fire.

D

Do not use damaged power cords, plugs or loose outlets. Fire or electric shock 
could result.

E

Use only the specified battery charger to recharge batteries. Other chargers may 
be of different voltage rating or polarity, causing sparking which could lead to fire 
or burns.

D

Do not use the battery or charger for any other equipment or purpose. Fire or 
burns caused by ignition could result.

H

Do not heat or throw batteries into fire. An explosion could occur, resulting in 
injury.

E

To prevent shorting of the battery in storage, apply insulating tape or equivalent to 
the terminals. Otherwise shorting could occur, resulting in fire or burns.

D

Do not use batteries or the battery charger if wet. Resultant shorting could lead to 
fire or burns.

D

Do not connect or disconnect power supply plugs with wet hands. Electric shock 
could result.

F

Do not touch liquid leaking from batteries. Harmful chemicals could cause burns 
or blisters.

D

Do not use within the vicinity of hospitals. Malfunction of medical equipment could 
result.

E

Use the instrument at a distance of at least 22 cm from anyone with a cardiac 
pacemaker. Otherwise, the pacemaker may be adversely affected by the electro-
magnetic waves produced and cease to operate as normal.

D

Do not use onboard aircraft. The aircraft instrumentation may malfunction as a 
result.

D

Do not use within the vicinity of automatic doors, fire alarms and other devices 
with automatic controls as the electromagnetic waves produced may adversely 
affect operation resulting in an accident.
