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 CAU IONARY NO ES
• 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 fre uency, 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

1-2
• 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 omey
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.
1.1 CAUTIONARY NOTES

1.4 OUTLINE OF OPERATION
1.4 OU LINE OF OPERA ION
The AUTO ENSMETER T -100 is an instrument for the
automatic measurement of refractive and prism power of
spectacles and contact lenses.
The T -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 CD.

3. METHOD OF OPERATION
3.1 Preparation for operating
• Before turning on the power, check the following items:
- Make sure that the cover glass under the nose piece is clean.
- Make sure that the nose piece seated properly.
- Make sure a lens is not on the nose piece.
1) Connect the female end of the power cord into the power terminal on

3.2 MEASURING METHODS
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 amage 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.
2) Place the right lens on the nose piece with the bottom of the frame
away from you and the temple downward (as shown below).

5) When the right lens is removed from the nose piece, the instrument
is ready to measure the left lens.
6) Place the left lens on the nose piece as described in step 2 and
follow steps 3 4.
• When the left lens is place on the nose piece, "HOLD" will
isappear from the screen. However, the right lens ata will
be retaine , an if the Output button is presse after
measuring the left lens, ata for both lenses will be
isplaye .

b) Manual Hold Mode
• Thrusting the lens onto the nose piece or moving the lens
quickly may result in amage to the lens.
1) If the instrument is in automatic (AUTO) hold mode and you wish
to change to manual hold mode, press the HOLD button (located
below the nose piece) for approximately 1 second, until "AUTO"
disappears from the display.
2) Place the right lens on the nose piece with the bottom of the frame
away from you and the temples downward (as shown on page 3 3).
• The right lens must be measure first an then the left
lens.
