1. PRIOR TO USE
• Read this Operator Manual carefully before using this
instrument in order to operate it properly and safely.
• Do not use procedures other than those specified in this
manual.
1.1 CAUTIONARY NOTES
• Never install this instrument near locations where explosive
or flammable materials are used or stored. Such installation
may result in a fire or an explosion.
• Only well-trained personnel should operate this instrument.
• When installing this instrument, observe the following items.
- Do not install this instrument in a location where it might be
exposed to water or chemicals.
- Do not install this instrument in a location where it might be subject
to adverse influences, such as excessive atmospheric pressure,
high temperature, excessive humidity, poor ventilation, direct
sunlight, dust, salt or sulfur in the air.
- Ascertain that factors such as excessive slope, vibration and
impact will not endanger the instrument (including during
transportation).
- Do not install this instrument near the storage of chemical
substances or in a location where gas may be generated.
- Adhere to the specified mains frequency, voltage and allowable
current (or allowable power consumption).
• During use of this instrument, observe the following:
- Do not move a coated lens when it is held with the clamp. This
may result in damage to the coating. The clamp should be used
only for marking.
- Clean the cover glass under the nose piece often with a soft cloth.
- Always keep the tip of the nose piece clean. Dust on it may result
in scratches on a lens.
1.1 CAUTIONARY NOTES
1-1
• When this instrument is not in use, keep the dust cover over
it.
• When the instrument is not used for an extended period of
time, unplug the power cord.
• After using this instrument, observe the following:
- Do not apply excessive force when unplugging the cords.
- Refer to the Section 4.4 Storage for storage instructions.
• If you suspect that this instrument is not functioning properly,
do not attempt to repair it. Contact your Tomey
representative or local distributor.
• Do not modify this instrument.
• Maintenance:
- Inspect this instrument and its accessories periodically.
- If this instrument has been idle for a long period of time, confirm
that it is functioning properly and safely before using it again. For
this, TOMEY recommends using a trial lens set for checking
accuracy.
• Due to vibration during transport and/or environmental
changes of storage, the ink may leak out of the marking
device cartridge. If you find an ink stain and/or leakage of ink
at the tip of the marking device, wipe it off and make sure it is
functioning properly.

1.3 EXPLANATION OF TERMS
1.4 OUTLINE OF OPERATION
The AUTO LENSMETER TL-100 is an instrument for the
automatic measurement of refractive and prism power of
spectacles and contact lenses.
The TL-100 is composed of a built-in optical system, an
electronic processing system, and a mechanical system.
Placing spectacles or contact lenses on the nose piece initiates
automatic measurement. The results are displayed on the LCD.

3.2.1 MEASURING SINGLE VISION LENSES
If the instrument is not in Single Vision mode ( ), change to
Single Vision mode by pressing the MODE button. Single Vision
mode ( ), Multi-focal mode ( ) and Contact Lens mode ( )
are set consecutively each time the MODE button is pressed.
a) Automatic Hold Mode
In the automatic hold mode, readings are automatically held when
the lens is properly aligned.
• Thrusting a lens onto the nose piece or moving a lens
quickly may result in damage to the lens.
1) If the instrument is in manual hold mode and you wish to use
automatic (AUTO) hold mode, press the HOLD button for
approximately 1 second until "AUTO" appears at the upper left of
the screen.
