Installation, Features, and Functions
PT100 Setup
The PT100 is supplied in a convenient carrying case for easy and safe
transportation to remote locations. To setup the PT100, remove all of the
components and follow these instructions.
WARNING: POSITION THE PT100 SO THAT IT IS NOT DIFFICULT TO OPERATE
THE DISCONNECTION DEVICE (PLUG).
WARNING: CARE MUST BE TAKEN TO ARRANGE THE CABLES FOR THE AC-
CESSORIES SUCH THAT THEY DO NOT PRESENT A TRIPPING HAZARD TO THE
EXAMINER OR A DANGER TO THE PATIENT.
Full charging of the battery is required be-
fore using the PT100.
• Plug the female end of the power cord
into the connector on the underside of the
charging base and press the cord neatly
into the cord-retainer channel.
• Plug the male end of the cord into a power
outlet (100 to 240 VAC @ 50 to 60 Hz).
The green LED will illuminate to indicate that the base has power and
the amber LED will ash to indicate the base is in standby mode.
• Place the PT100 into the charging base, making sure that it is seated
properly and that the ON/OFF switch is placed in the OFF position.
The Amber light will illuminate. It will take about 3 hours to fully charge
the battery. A full charge will ensure maximum battery life.
Note: The instrument will charge in the ON position, however, the pro-
cess is slower and it will take longer to achieve a full charge.
• When the PT100 is fully charged the amber LED will go out. If the
PT100 is in the charging base and the amber LED is blinking, the unit
is not fully seated.
• Once charged, the instrument has an
operational usage of approximately
350 individual measurements before recharg-
ing is required. Operational usage will vary
depending on the use of features such as IR
data transmission and patient illumination. In
order to conserve the charge, users should
keep the power switch on the handle to the
OFF (O) position.
•
Note: If the PT100 is not used for extended periods
of time, the battery should be removed and
placed in its location in the carrying case.

PT100 Initiation
The PT100 utilizes a user-friendly icon-based operating system to
ensure ease of use. To initiate the system, simply press any of the
function buttons on the control panel.
Battery Indicator
The PT100 has a battery indicator located in the upper right-hand
corner of the display. The amount of charge is indicated by the black
ll inside the battery icon. The battery is fully charged when the icon
is completely black.
The black ll moves from right to left (towards the “head” of the battery)
while charging. During instrument use, the black ll moves from left to
right to indicate the amount of charge remaining.
Sleep Mode
To conserve battery power, the PT100 has a sleep mode that activates
after 2 minutes of inactivity. Press any button to bring the instrument
out of sleep mode. The LCD screen will turn on and the instrument will
be ready for use. In addition to the display being
on, the blue alignment crosshair, viewed through
the eyepiece, indicates that the instrument is
on. If the crosshair is not visible the PT100 is in
sleep mode. When bringing the instrument out
of sleep mode, be careful to press a button only
once. Pressing a button more than once may in-
advertently turn an instrument function on or o󰀨.
Printer Setup
The printer available for the PT100 system is a battery powered, wire-
less, infrared printer. Batteries are included. Remove the printer from
its packaging and follow the instructions provided in the communication
section of this manual.
Installation, Features, and Functions (Cont’d)
On/O󰀨 Switch

Measurement Mode
Alignment System
The PT100 features an alignment system that guides the user to the
correct position on the patient’s cornea. Once properly aligned, the
instrument automatically takes an IOP measurement. The alignment
system is viewed through the instrument’s eyepiece and utilizes a se-
ries of easy to follow visual indicators. A varying-diameter blue circle
indicates distance from the eye and a crosshair is used to obtain proper
directional alignment. When the PT100 is moved within the required
working distance from the eye (approximately 12 mm or 1/2 inch), the
alignment indicators become superimposed over the patient’s eye.
The illustration below shows the components of the alignment system
indicators and their signicance.
In order to take a measurement the PT100 must be in the measurement
mode. To bring up the measurement mode screen, select Exit from the
SETUP mode or press any button to bring the instrument out of sleep
mode. The illustration below depicts the measurement mode screen.
