PLEASE READ THIS FIRST:
Your choice of the SONIN COMBO PRO shows
you are a professional who demands quality and
value from your tools Please take a few minutes
to read this manual Your SONIN COMBO PRO
has many easy-to-use features that will make your
measuring tasks faster and easier once you
understand them
The SONIN COMBO PRO is actually two measur-
ing tools in one It can take measurements by
bouncing sound waves off flat hard surfaces such
as walls or ceilings from 1 ft 6 ins (46cm) up to
60 ft (18m) in the SINGLE UNIT MODE or
from 3 ft (1 m) up to 250 ft (75m) by sending
infrared light signals to the Target (included) and
receiving sound waves back from the Target in
DUAL UNIT MODE
Use the SINGLE UNIT MODE primarily for
indoor measurements or whenever you are
measuring to a suitable, hard, flat surface, less
than 60 ft (18m) away
Use the DUAL UNIT MODE when you need
to measure distances greater than 60 ft (18m),
when there is no suitable surface to bounce the
signal off of, or when there are obstacles partially
blocking the measuring path [ If you can see the
Target (and it is within range), the COMBO PRO
can take a measurement ]

HELPFUL MEASURING HINTS
FOR SINGLE UNIT MODE
MEASURING:
1) Measurements cannot be taken through glass
or off of soft or padded surfaces
2) The SONIN COMBO PROs range and ability
to measure in tight spaces can be increased
Stand in the middle of the distance to be
measured and add measurements taken in
opposite directions
3) When measuring in confined spaces (hallways),
try to measure down the center line and midway
between the floor and ceiling
4) To find a specific distance from a wall, walk
toward or away from the wall while holding
down or
5) When the surface being measured to has pro-
trusions and recesses, you can determine
where the beam is hitting Move sideways
parallel to the target surface, while holding
- 5 -
down the measure button You will see the
distance increase for recesses and decrease
for protrusions
6) Be sure the surface you are measuring to is
hard, flat and uniform Some surfaces such as
stucco or clapboard may scatter signals
7) When using tracking mode, the unit may lock
on to a stronger (usually closer) measurement
If this happens, release the measure button
and try again
8) REMEMBER:
Measures from bottom of unit

HELPFUL HINTS FOR DUAL UNIT
MODE MEASURING:
1) Make certain there is a clear line of sight
between the Receiver and the Target
2) Use validate mode when taking measurements
near traffic, construction or other noise sources
3) The Target is not affected by noise If there
are loud noise sources such as machinery,
traffic, etc , arrange the measurement so the
Receiver is furthest from the noise source
4) Use DUAL UNIT MODE Operation
even for short measurements [under 60 ft
(18m)] if there are obstacles in the path of the
measurement SINGLE UNIT MODE
Operation requires a path 1 ft (30 cm) wide
for each 10 ft (3m) of measured distance
For example, at 60 ft (18m), SINGLE UNIT
MODE Operation requires a path 6 ft
(1 8m) wide and high DUAL UNIT MODE
Operation only requires that the Receiver is
- 7 -
able to see the Target
5) If the wind is gusting, make certain you use
validate mode for measurements See the
section on ENVIRONMENTAL ONDI-
TIONS
6) When measuring distances beyond the
maximum range (see section on ENVIRON-
MENTAL ONDITIONS) break the measure-
ment into 2 or more measurements and use
the ADD function to sum them
REMEMBER:
Your COMBO PRO will automatically power
down and lose all measurements 7 minutes
after the last key press

TEMPERATURE OMPENSATION:
Because temperature affects the speed of sound,
the SONIN COMBO PRO has automatic tempera-
ture compensation for greater accuracy In order
to make the most of this feature, wait 1 minute for
each 1°F (2 minutes for each 1°C) of temperature
difference between cool and warm locations
DISPLAYING TEMPERATURE TO IMPROVE
A URA Y: Since temperature affects accuracy,
the SONIN COMBO PRO is most accurate when
its internal temperature matches the air temperature
To display temperature: press and hold
key, then press key, the internal temperature
will appear on the display immediately (in °C when
m display units are selected or in °F if selected
display units are ft:in, ft:ft, yds)
For Example:
To go back to measurement mode, press and
release key or press the measure key directly
HINT: To speed equalization of the SONIN
COMBO PROs internal temperature versus air
temperature, wave the unit back and forth in the
air to circulate room temperature air through the
unit For additional information, see "Temperature"

ENVIRONMENTAL ONDITIONS
THAT OULD AFFE T PERFORMAN E:
IMPORTANT: Ultrasonic Distance Measuring,
Tools work best for quick and easy measuring and
estimating They are not intended for precision
work, although they can be very accurate under
optimal conditions
Humidity - Humidity and temperature can affect
the range and accuracy of all ultrasonic distance
measuring tools They may give measurements
that are longer or shorter than their specifications
(depending on atmospheric conditions) The range
is longest in high temperature/high humidity and
low temperature/low humidity and range is shortest
in high temperature/low humidity and low
temperature/high humidity
Humidity effects on accuracy are greatest at high
temperatures and negligible at low temperatures
At 100°F (38°C) and 99% R H , the distance
measurement will be short by 0 6% At 100°F
(38°C) and 0% Relative Humidity, the distance
measurement will be long by 0 6% At 32°F (0°C)
the distance measurement will essentially not be
affected by humidity
Temperature - Your SONIN COMBO PRO has
unique automatic temperature compensation to
ensure consistency of measurements between 32°F
and 100°F (0°C to 38°C) The response rate of
this circuitry enables you to move between warm
and cold areas and measure with reasonable
accuracy However, we recommend that you do
not leave your SONIN COMBO PRO in very cold
or very hot conditions (e g sunlight in a car), as
the unit will then require more time to adjust to air
temperature
- 17 -
As long as the internal temperature is equal to the
air temperature, accuracy is unaffected Wait for
the unit's internal temperature to equal the air
temperature or, add 1% of the measured distance
for each 10°F (5 5°C) that the measured tempera-
ture is below the actual temperature; subtract 1%
of the measured distance for each 10°F (5 5°C)
that the internal temperature is above the air
temperature (See section on DISPLAYING
TEMPERATURE for instructions on how to obtain
a temperature measurement from your SONIN
COMBO PRO )
Altitude/Barometric Pressure - Altitude and
barometric pressure can affect the range and
accuracy of all ultrasonic distance measuring tools
As the altitude increases (barometric pressure
decreases), the range is reduced As altitude
decreases (barometric pressure increases), the
range is increased
To correct for altitude (pressure) effects on accuracy,
subtract 0 4% of the measured distance for each
1000 ft/ - 0 6" Hg (0 3 km/-15mm Hg) you are
above sea level Add 0 4% of the measured
distance for each 1000 ft/ +0 6" Hg (0 3km
/+15mm Hg) you are below sea level (sea level
= 760mm Hg)
Noise - High frequency noise from machinery,
engines, computers, stereos, TV sets, etc can affect
the reading and you may get random readings
Stand away from or shut off this type of equipment
when measuring
Outdoor Measurements - Your SONIN
COMBO PRO is designed for indoor and outdoor
use, provided there is only light wind A strong
wind will tend to affect accuracy and/or range
- 18 -
FIELD ALIBRATION:
This unit was calibrated under the circumstance
of 760 mmHg atmosphere and 50% relative
humidity, if the unit is not used under such environ-
mental conditions, it may produce an error The
built in users calibration mode is designed for the
user working under other than standard conditions
such as high altitudes After the unit is calibrated
all environmental errors are compensated and the
accuracy is improved
To Field alibrate unit -
1) Turn the switch to the position
2) Place unit 10 feet (or 3 meter) from the bottom
of the unit to a flat vertical surface
3) Press and hold both and keys then
press key, the unit will turn on and process
calibration immediately
4) When calibration is completed 10 00 ft ft
(or 3 00 m) will displayed on the LCD
5) Then turn off the unit and turn on again, the
new calibrated data will now used in all
measures
NOTE - BEFORE ALIBRATING UNIT:
1) It is imperative that the unit be exactly 10 feet
(imperial) or 3 meter (metric) from the bottom
of the unit to a flat vertical surface
2) Verify the temperature of the unit is within
± 1°C of the ambient temperature
