NTRODUCTION

I

The TED 191 Portable Oxygen Monitor is an easy-to-use, portable instrument that provides fast
and accurate oxygen monitoring and audio-visual alarm capability. The TED 191 is designed to
monitor concentrations of up to 100% oxygen in medical gas mixtures.

The TED 191 Portable Oxygen Monitor is designed and manufactured in accordance with strict
performance and quality protocols and subject to ISO 9002 Quality System protocols. When used
correctly, this instrument will provide you with many years of trouble free service.

The TED 191 Portable Oxygen Monitor is a compact, self-contained unit, which is battery powered
by four (4) dry cell batteries (size AA/penlight).

PPLICATIONS

A

The instrument is designed for the measurement of oxygen concentrations in a variety of medical
gas mixtures. It is recommended that the instrument be used only as a secondary measuring
device to verify the concentration of oxygen in gas mixtures prepared using a gas blender or
similar apparatus. The use of this monitor as a primary or only means of preparing gas mixtures is
not advised.

The monitor is capable of verifying oxygen concentrations in gas mixtures used in:

• Anesthesia

• Neonatal Intensive care

• Adult Intensive care

• Respiratory / Oxygen Therapy

Calibration Control

I O

Calibration Control Allows the operator to calibrate the instrument to one primary set

point (usually 100%) in accordance with the designated calibration
protocol. This protocol is defined further in this manual and also.
Instructions in abbreviated form can be found on the top of the
monitor casing.

High Alarm Setting Allows the operator to define a high alarm threshold limit. Range

18% to 102% - if the actual measured value as displayed on the
LCD exceeds this set threshold, an audible and visual alarm
condition will be invoked.

Low alarm setting Knob Allows the operator to define a low alarm threshold limit. Range

18% to 100% - if the actual measured value as displayed on the
LCD falls below this set threshold, an audible and visual alarm
condition will be invoked.

Liquid Crystal Display Displays measured oxygen concentration, low battery condition

and provides a visual indication of either a high (+) or low (-) alarm
threshold violation.

NSTALLING THE BATTERIES

Withdraw the battery drawer from the monitor casing, by grasping the side lugs located on
either side of the battery drawer, and, firmly pinching them inwards, simultaneously pull the
drawer outwards. When new, this action can be somewhat stiff and difficult to execute. Care
should be taken not to damage either the drawer or the casing of the monitor when
executing this procedure.

Fresh batteries must be inserted into the four battery recepticles located within the battery
drawer assembly. Care should be taken to ensure that the correct battery polarity is
maintained.

Caution : Improper installation of the batteries may result in heat damage to the

batteries.

Re-insert the battery drawer into the monitor casing, and close.
