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). TELEDYNE ELECTRONIC TECHNOLOGIES Analytical Instruments APPLICATIONS 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 TELEDYNE ELECTRONIC TECHNOLOGIES Analytical Instruments DESCRIPTION OF FUNCTIONAL ZONES FRONT PANEL High Alarm Setting Knob Alarm Mute Button Calibration Control 50 60 40 70 TELEDYNE 30 80 HI 21 90 102 50 60 X 21 40 70 30 80 LO % OXYGEN 21 90 OXYGEN MONITOR I O 102 Low Alarm Setting Knob Liquid Crystal Display (LCD) On / Off Switch On / Off Switch Allows the operator to turn the instrument on and off. Alarm Mute Switch Allows the operator to “mute” the sound of the audible alarm signal for ± 60 seconds. During this time, a red signal lamp will flash, indicating a “muted” alarm condition is in force. 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 sett...
