1.0 INTRODUCTION
1.1 Component Identification
LCD DISPLAY: A 3-digit display provides a
direct readout of oxygen concentration in
the range of 0 - 100%. The display is blank
when the Handi+ enters its Sleep (power
off) mode. The Handi+ will automatically
enter the Sleep mode after approximately
1.3 minutes from the last time the ON button
was pressed.
ON/OFF BUTTON: Use this button to turn the
Handi+ on and off. When the Handi+ is in the
Sleep (power off) mode, the LCD display is
blank. The analyzer turns off after 1.3 min-
utes if no buttons are pressed.
CALIBRATION BUTTON: Press the calibration (CAL) button to adjust the calibration value to
reflect the known oxygen concentration. To simplify operation, the Handi+ Analyzer automati-
cally determines the calibration gas being used as room air (20.9%) or high grade (100%).
FLOW DIVERTER: The flow diverter is designed to fit industry standard 15 mm I.D. "T" adapters.
OVER RANGE INDICATOR: The appearance of a decimal point after the first digit means that the
Handi+ is reading in excess of 99.9%.
Example: 0.0.0 = 100% 0.0.1 = 101% 0.0.2 = 102%
(If the display reads > 0.0.3 the Handi+ should be re-calibrated.)
1.2 Description
The Maxtec Handi+ oxygen analyzer is designed to monitor oxygen concentration in the patient-
breathing environment. It is one of a full line of oxygen analyzers by Maxtec. The Handi+ oxygen
analyzer utilizes the Maxtec MAX-250 oxygen sensor and is engineered for fast response, maxi-
mum reliability and stable performance. The Handi+ is designed primarily for spot-checking of
oxygen levels delivered by medical oxygen delivery equipment and respiratory care systems.
Its lightweight, compact size, extended battery life, and "auto off" feature makes this oxygen
analyzer ideal for portable oxygen analysis by qualified heath care professionals.
2.0 CALIBRATING THE HANDI+
2.1 Before You Begin
A protective film covering the threaded sensor face must be removed and the sensor allowed
to “breath” for at least 30 minutes. Next, the Handi+ Oxygen Analyzer should be calibrated.
Thereafter, Maxtec recommends calibration on a weekly basis. However, more frequent cali-
bration will not adversely affect product performance.
2.2 Calibrating the Handi+ Oxygen Analyzer
Calibration of the instrument is necessary if the temperature of the gas stream changes by
more than 3 degrees Celsius.
Changes in elevation result in calibration error of approximately 1% of reading per 250 feet. In
general, calibration of the instrument should be performed when the geographic elevation at
which the product is being used changes by more than 500 feet.
In addition, calibration is recommended if the user is unclear when the last calibration proce-
dure was performed or if the measurement value displayed is in question.
Calibrate the Handi+ to an oxygen source, which has a traceable certificate and/or USP certifi-
cation, of either 20.9% oxygen, as found in room air, or 100% oxygen. It is recommended that
the oxygen source be documented at a pressure and flow similar to your clinical application.
NOTE: Before beginning calibration the Handi+ must be in thermal equilibrium. You may also
need to be aware of other factors, which affect device calibration values. For more informa-
tion, refer to section 4.0 "Factors Influencing Calibration and Performance" of this manual.
NOTE: We recommend use of medical grade USP or >99% purity oxygen when calibrating the
Handi+.
2.3 In Line Calibration (Configuration A)
1. Put the Handi+ in an upright position such that you can read the product label.
2. Connect a sample supply hose to a standard "T" adapter The Maxtec "T" is
precision-tapered to insure a tight connection with O-rings of the MAX-250 oxygen
sensor diverter.
3. Insert the Handi+ in the center position of the "T" adapter.
4. Attach an open-ended reservoir to the end of the "T" adapter. Then start the
calibration flow of oxygen at 1-10 liters per minute.
NOTE: Six to 10 inches of corrugated tubing works well as a reservoir.
NOTE: A calibration oxygen flow to the Handi+ of 2 liters per minute is recommended to mini-
mize the possibility of obtaining a "false" calibration value.
5. Allow the oxygen to saturate the sensor. Although a stable value is usually
observed within 30 seconds, allow at least 2 minutes to ensure that the sensor is
completely saturated with the calibration gas.
6. If the Handi+ is not already turned on, do so now by pressing the analyzer ON
button .
7. Press the “CAL” button on the Handi+. The calibration gas value on the
analyzer display should read 20.9 or 100 depending on the gas stream used.
2.4 Direct Flow Calibration (Configuration B)
1. Attach the Barbed Adapter to the Handi+.
2. Connect the clear sampling tube to the Barbed Adapter.
3. Attach the other end of the clear sampling tube to a source of oxygen with a
known oxygen concentration value and initiate flow of the calibration gas to the
unit at a rate of 1-10 liters per minute (2 liters per minute is recommended).
4. Allow the oxygen to saturate the sensor. Although a stable value is usually
observed within 30 seconds, allow at least 2 minutes to ensure complete
saturation of the sensor with the calibration gas.
5. If the Handi+ is not already turned on, do so now by pressing the analyzer “ON”
button .
6. Press the “CAL” button on the Handi+. The calibration gas value on the
analyzer display should read 20.9 or 100 depending on the gas stream used.

3.0 OPERATING THE HANDI+
To Check the Oxygen Concentration of a Sample Gas:
1. Maintain the Handi+ in an upright position such that you can read the product
label.
2. Place the Handi+ in the sample gas stream.
IMPORTANT: When using a standard "T" adapter, make sure that the sensor is mounted in the
adapter with the flow diverter pointing down. Make sure that there is a tight fit between the
flow diverter and the "T" adapter.
3. Start the flow of the sample gas to the sensor.
4. Allow the oxygen sensor to remain in the flow of the sample gas until stable.
5. If the Handi+ is not already turned on, do so now by pressing the analyzer ON
button .
6. Read the value displayed on the LCD.
NOTE: If the Handi+ is used to measure the oxygen concentration with equipment using a
heated or humidified gas stream, it is recommended that the Handi+ be placed upstream of
the heater and/or humidifier. For more information, refer to "Factors Influencing Calibration
and Performance" below.
For hospital and home care a new calibration is required when:
•The measured O2 percentage in 100% O2 is below 97.0% O2
•The measured O2 percentage in 100% O2 is above 103.0% O2.
For ID testing (or optimum accuracy), a new calibration is required when:
7. The measured O2 percentage in 100% O2 is below 99.0% O2.
8. The measured O2 percentage in 100% O2 is above 101.0% O2.
4.0 FACTORS INFLUENCING
ACCURATE READINGS
4.1 Elevation Changes
•Changes in elevation result in a reading error of approximately 1% of reading per
250 feet.
•A change in altitude greater than 500 ft will require sensor recalibration.
•This device does not automatically compensate for changes in barometric pressure
or altitude. If the device is moved to a location of a different altitude, it must be
recalibrated before use (see section 2.2).
4.2 Temperature Effects
The Handi+ will hold calibration and read correctly within ±3% when in thermal equilibrium
within the operating temperature range. The device must be thermally stable when calibrated
and allowed to thermally stabilize after experiencing temperature changes before readings
are accurate. For these reasons, the following is recommended:
•When used in a breathing circuit, place the sensor upstream of the heater.
•For best results, perform the calibration procedure at a temperature close to the
temperature where analysis will occur.
•Allow adequate time for the sensor to equilibrate to a new ambient temperature.
4.3 Pressure Effect
Readings from the Handi+ are proportional to the partial pressure of oxygen. The partial pres-
sure is equal to the concentration times the absolute pressure. Thus the readings are pro-
portional to the concentration if the pressure is held constant. Flow rate of sample gas can
affect pressure at the sensor in that back pressure at the sensing point may change. For these
reasons, the following is recommended:
•Calibrate the Handi+ at the same pressure as the sample gas.
•If sample gases flow through tubing, use the same apparatus and flow rates when
calibrating as when measuring.
•The Handi+ oxygen sensor has been validated at pressures up to 2 atmospheres
absolute. Calibration or operation above this pressure is beyond the intended use.
4.4 Humidity Effect
Humidity has no effect on the performance of the Handi+ other than diluting the gas, as long
as there is no condensation. Depending on the humidity, the gas may be diluted by as much as
4%, which proportionally reduces the oxygen concentration. The device responds to the actual
oxygen concentration rather than the dry concentration. Environments where condensation
may occur are to be avoided since condensate may obstruct passage of gas to the sensing
surface, resulting in erroneous readings and slower response time.
For this reason, the following is recommended:
•Avoid usage in environments greater than 95% relative humidity.
•When used in a breathing circuit, place the sensor upstream of the humidifier.
5.0 CALIBRATION ERRORS AND
ERROR CODES
The Handi+ analyzers have a self test feature built into the software to detect faulty calibra-
tions, oxygen sensor failures, and low operating voltage. These are listed below, and include
possible actions to take, if an error code occurs.
E03: No valid calibration data available
Make sure unit has reached thermal equilibrium. Press and hold the Calibration Button for
three seconds to manually force a new calibration.
E04: Battery below minimum operating voltage
Unit is at end of life, see "Product Disposal Instructions" for proper disposal.
CAL Err St: O2 Sensor reading not stable
Wait for displayed oxygen reading to stabilize when calibrating the device at 100% oxygen.
Wait for unit to reach thermal equilibrium (Please note that this can take up to one half hour,
if the device is stored in temperatures outside the specified operating temperature range).
CAL Err lo: Sensor voltage too low
Press and hold the Calibration Button for three seconds to manually force a new calibra-
tion. If unit repeats this error more than three times, contact Maxtex Customer Service for
possible sensor replacement.
CAL Err hi: Sensor voltage too high
Press and hold the Calibration Button for three seconds to manually force a new calibra-
tion. If unit repeats this error more than three times, contact Maxtec Customer Service for
possible sensor replacement.
CAL Err Bat: Battery voltage too low to recalibrate
Unit is at end of life, see "Product Disposal Instructions" for proper disposal.
6.0 CLEANING AND MAINTENANCE
When cleaning or disinfecting the Handi+, take appropriate care to prevent any solution from
entering the analyzer.
•The Handi+ surface may be cleaned using a cloth moistened with 65% isopropyl
alcohol/water solution or germicidal wipe.
•The Handi+ may be disinfected using standard topical disinfectants.
•The Handi+ is not intended for steam, ethylene oxide or radiation sterilization.
•Store the Handi+ in a temperature similar to its ambient environment of daily use.

9.0 FREQUENTLY ASKED
QUESTIONS
After I calibrate to 20.9%, the display changes as
much as ± 1%.
•This is within the normal Handi+ operating tolerance of ± 1% when temperature
and pressure are constant.
I have calibrated to 99.9% but when I check my oxy-
gen delivery equipment, the Handi+ reads ".0.4" or
greater (Over Range Indicator).
•It is recommended that you conduct the calibration procedure again to get
another reading. The most likely cause is that the Handi+ has received a "false"
calibration value.
•Make sure that the calibration gas is connected to the Handi+ at 2 liters per minute
for a minimum of 2 minutes prior to proceeding with calibration.
•This 2-minute equilibration time is necessary to insure that the sensor is
completely saturated with the calibration gas.
I have found the reading to drift greater than ± 3%
from a know source value. What is the possible cause?
•The sensor may be at or near its useful life.
•Replace your Handi+.
•Sensor life is dependent on the oxygen concentration exposure.
For example, a sensor which is used to check flow meters once a week for 8 hours
will outlast one which is used to analyze oxygen blender performance 24 hours
per day, 5 days a week.
