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.

Cause 3: The cover glass under the nose piece is not clean.
Action: Turn off the power. Remove the nose piece and then
clean the cover glass (See Section 4.2.1, Cleaning cover
glass). Replace the nose piece and turn the power on
again.
3) "INITIAL ERR!" is Displayed.

5.1 Troubleshooting guide
5.1.2 Progressive Addition Lens Measurement
1) The Cursor Cannot be Centered in the Progressive Channel.
Cause 1: With progressive lenses which have a small power difference
between the far point area and the near point area, aligning the
cursor to the center may not be achievable.
Action : The beginning of the progressive channel is located in
approximately the center of the lens or the center of the
frame. Take measurement around that position and press
the HOLD button.
2) The Cursor Cannot be Centered in the Far Point Area.
Cause 1: Progressive lenses are sometimes dispensed for intermediate
and near correction only. In such lenses, the progressive area
extends into the far point area and it is difficult to accurately
measure the far point area.
Action: Take a reading near the top of lens.
Slightly move the lens back and forth, right and left, near
the central top portion of the lens. Regard the area where
the SPH value varies the least as the measurement of the
far point area. Press the HOLD button when this location
is found.
3) The Near Point Area is not Detected. (The Cursor does not Change to " " or
" ".)
Cause 1: The near point area is NOT automatically detected if the ADD
power is less than 1.0 diopter.
Action: Press the HOLD button when judging the highest
addition value when the cursor is in the progressive zone.
Cause 2: The near point area in frame lenses with a long progressive
zone may be positioned very near the edge of the frame or even
outside of the frame. It may not be possible to detect the near
point in such lenses.
Action: Press the HOLD button when judging the highest
addition value when the cursor is in the progressive zone.
5.1 TROUBLESHOOTING GUIDE
5-3
Cause 3: The near point area in a small frame lens may be positioned
very near to the edge of the frame or even outside of the frame.
It may not be possible to detect the near point area in such lenses.
Action: Press HOLD button when judging the highest addition
value when the cursor is in the progressive zone.
4) The ADD Readings are Significantly Lower (> 0.5 diopters) than the Nominal
Values.
Cause 1: The far point area was not measured properly.
Action : With some lenses, the far point area may not be measured
accurately if AUTO HOLD mode is used. Disable the
AUTO HOLD mode in Setup (See Section 3.4, Setup
Menu 3), and measure the far point area manually. If it is
still difficult to measure, slightly move the lens back and
forth, right and left to measure the portion where
variation of SPH readings is minimum and press the
HOLD button.

5.1 TROUBLESHOOTING GUIDE
Cause 2 : TL-100 senses refractive power change along the
progressive extent. If the power change is close to 0 diopter, the
TL-100 treats it as a near point.
Example:
When a lens with a SPH reading of -1.00 diopters and an add
reading of 2.00 diopters is measured, there is a point where the
total refractive power (S + ADD) equals zero (0) diopters. As a
result, the ADD value would be displayed as 1.00 diopter.
Action : Use manual mode for these lenses.

5) The ADD Readings are Higher than the Nominal Value.
