IMPORTANT! Do not move the spindle too
quickly or apply excessive lateral force to the
spindle.

To use this instrument properly, read this user's manual
prior to use. Before using this instrument for the first time,
inspect all components to ensure proper performance.

OPERATING ENVIRONMENTS

IMPORTANT! Use this instrument in environments
where the temperature is between 32°-104°F
(0°-40°C) and the humidity is between 30% and

70% with no condensation.

• Use this instrument in places that are free from dust,
oil or oil mist and are not exposed to direct sunlight.

PAGE 1 OF 4 0616 IH-2781

• Check the performance and accuracy before use if
the instrument is dropped or sustains an impact.

• Check that the movement of the long hand, short
hand and spindle are smooth. Also check if the LCD
is working normally.

• Check that the contact point, anvil, back plate and
screws on the lever mount are not loose.

• Zero the instrument frequently using a master gauge
if used in a place with significant temperature
fluctuation.

BATTERY-RELATED WARNINGS

WARNING! If the battery is misused or abused,
leaking or subject to extreme conditions,
explosion and/or fire can result. Observe the
following precautions to avoid instrument failure
or malfunction.

• Do not disassemble, deform, short-circuit, charge,
heat the battery to 212ºF or over or throw the battery
into a fire.

• Always insert the battery correctly according to the
polarities (+ and – ) marked on the battery and the
instrument.

• Always use the recommended battery.

• If the instrument will not be used for more than three
months, remove the battery and store it separately.

• When discarding or storing the battery, cover the
positive (+) and negative (–) terminals with insulating
tape to prevent contact with other metals. When
disposing of it, follow the ordinances or regulations
of the local government.

• Keep the battery away from direct sunlight, high
temperature, high humidity and out of the reach of
children.

• Do not swallow the battery. If swallowed, consult a
physician immediately.

• Should the content of the battery contact the
eyes or skin, or enter the mouth, rinse with water
immediately and consult a physician. Should it
adhere to clothing, wash the clothing with water.

DISPOSAL WARNINGS

WARNING! A liquid crystal display and a
silver oxide battery are used in this product.
When disposing of the instrument, follow
the ordinances and regulations of the local
government.

• The liquid crystal display contains an irritating
substance. Should the liquid content contact the
eyes or skin, or enter the mouth, consult a physician
immediately.

IMPORTANT! Do not strike the instrument or
allow it to be struck. Do not drop or apply
excessive force to it.

• Do not disassemble or modify.

• Do not use an electric engraving pen or other such
devices on the instrument. It may cause damage.

REPLACING BATTERY

Use a silver oxide battery (SR44).

1. Remove the battery holder using a screwdriver.

2. When replacing the battery, remove the spent battery.

3. Install a new battery into the battery holder with its
positive (+) side facing the front of the instrument.

4. Replace the battery holder into its original position.

IMPORTANT! A battery is not installed in this
instrument at the factory. Install the battery
before using.

• If the battery holder is not installed properly, the
instrument may not display the correct value or a
malfunction may result.

• If MEASUREMENT mode is not automatically entered
after executing the above procedure, reinstall the
battery.

SETUP

• When the battery is installed, nonsensical numbers
or an "E" may be displayed on the readout. This is
not a malfunction. Zero the instrument, then perform
the measurement.

• If the instrument will not be used for more than three
months, remove the battery and store it separately
to prevent damage by battery leakage.

NOTE: Do not use a sharp-pointed tool to
remove the battery holder and do not pry the
battery holder out.

• The supplied battery is used only to check the
functions and performance of the instrument.
It may not meet the battery life specification.

• If the battery is removed, zeroing is cancelled.
After installing the battery, perform the steps to zero
the instrument.

SETUP CONTINUED

ZEROING THE INSTRUMENT

Press and hold the ORIGIN button for more than one
second. The origin will be set, indicating "0.000/0.00mm"
or "0.00000/0.0000in" on the display.

TIPS

• Right after the battery is installed, nonsensical
numbers, or an "E" may be displayed in the readout.
This is not a malfunction. Zero the instrument, then
perform measurement.

• A rubber damper has been attached to the spindle
as a shock absorber. The elasticity of the damper
may cause the indicated value to not stabilize at
the bottom of the stroke, but this will not cause any
operational problems.

OPERATION

This thickness gauge is a measuring instrument for
quickly and accurately measuring the thickness or
outside diameter of an object.

1. To operate this instrument, first hold the frame and push
down the lifting lever by the thumb. (See Figure 1)
The spindle will move up and the contact point will
move away from the anvil, providing a space that
allows an object to be inserted.

• Also, the spindle may feel heavy at the bottom of
the stroke when this indicator is first used. This can
be resolved by pushing the spindle up once.

SETTING THE COUNT DIRECTION

The +/– button switches the count direction of display
values with respect to the spindle direction. The "▼" sign
appears in the upper left of the LCD if the indicator is set
so that it counts down when the spindle is retracted.

• The zero position may change due to thermal
expansion and contraction of the spindle, frame,
etc., caused by variations in ambient temperature.
Reduce temperature fluctuation during
measurement to a minimum. Zero the instrument
before using for the first time or when a significant
temperature fluctuation is unavoidable.

• This instrument may not be able to properly hold
large objects in position for measurement.
(See Figure 2)

2. Next, insert the object in the space, then slowly
release the spindle to see a reading on the
indicator.

IMPORTANT! Damage to the indicator or the
contact point may result if the spindle is moved
too quickly when measuring an object.

• This may result in a fluctuation of indicator readings.
If the object is too large, hold it in your hand to
stabilize it.

Plastic

Spacer

NOTE: Plastic spacers have been inserted in

the lever slide unit. (See Figure 2) They are
used for assisting the lever operation. Never
remove the spacers.

MAINTENANCE

IMPORTANT! Wipe off stains on the spindle
sliding face with a dry cloth or a cloth
dampened with a small amount of alcohol.
Do not lubricate the spindle at this time.

• Wipe off stains on the dial cover or the digital
display surface with a soft, dry cloth or a cloth
dampened with a small amount of neutral
detergent. Be sure to use only a neutral detergent.

• To clean the indicator, use a soft cloth soaked in
a diluted neutral detergent. Do not use organic
solvent (thinner or benzene). It may deform or
damage the indicator.

• Deterioration of instrument performance is
caused mostly by harsh operating conditions. It is
recommended that the instrument be periodically
inspected, the frequency being determined by the
amount of use, environment and the way in which the
instrument is used.

TROUBLESHOOTING

ERROR MESSAGE OPERATING ISSUE RECOMMENDATIONS

The battery is depleted. Replace the battery.

Err C

E

Water drops may have formed on the detector
unit due to sudden thermal change, or the
detector unit may be contaminated due to
other causes.

An ABS data composition error occurred while
the spindle was moving at high speed.

If this message still appears after two hours of thermal
stabilization, the instrument needs to be repaired.
Contact Uline Customer Service at 1-800-295-5510.

Continue using the instrument, since this error does not
affect measured values.

If this error occurs while the spindle is stopped, it
could be due to sensor failure. In this case, contact
Uline Customer Service at 1-800-295-5510.

If the problem persists, or if the troubleshooting section does not resolve or describe your problem, contact

Uline Customer Service at 1-800-295-5510.
