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

Measures from top of unit

TAKING A MEASUREMENT IN

DUAL UNIT MODE:

4) Place the Target at one end of the distance

to be measured

NOTE: The measurement will be taken to the

back of the Target

5) Walk with the Receiver to the other end of

the distance to be measured and aim the

Receiver directly at the face of the Target

Aiming at an angle to the face of the Target

will decrease the maximum distance the

COMBO PRO can measure

6) Make certain you have a clear path to the

Target

ft:ft or yds) Press and hold button until

desired mode displays, then release

NOTE: Unit will now default to your preset

mode even after unit is turned off

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

Possible causes for Error 1 and Error 2 include:

a) Measurement out of range [1 5 to 60 ft

(0 46 to 18 2 m) without Target, 3 to 250

ft (1 m to 75 m) with Target]

b) Unit is not perpendicular to the surface or

Target (See Fig 2 )

c) Surface is not hard and flat

d) Interference from nearby noise sources Try to

position the Receiver as far from the noise

source as possible or turn off the machinery

causing the noise (see section on ENVIRON-

MENTAL ONDITIONS)

e) Receiver or Target was moved during the

measurement The distance between the two

units must not be change during the reading

f) Excessive wind

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"

in the section on Environmental onditions
