OPERATING INSTRUCTIONS
ON/OFF BUTTON
Press N/ FF button to enter measurement mode. It will
display the angle reading immediately. Unit is now ready to
measure angle. Push N/ FF button again to shut off unit.
HOLD BUTTON
If you want to lock the reading while performing a measure-
ment, simply press the H LD. The angle reading will freeze
and you can record the reading. You can cancel this function
by pressing the H LD button a second time. You will now
be viewing live angle measurements.
Absolute ero mode: If the
icon “ABS” is in the display,
the unit is in absolute zero
measurement mode.
Note: changing from relative
to absolute zero mode can-
not be done when the H LD
icon is visible.
ABSOLUTE (HORI ONTAL) ERO MEASUREMENT
In absolute zero measurement mode, the icon “ABS” is vis-
ible. Put the unit near the joint needed to be measured. The
inclinometer shows the angle between the inclinometer
plane and the horizontal plane (see diagram to the right). To
get the most accurate reading, allow the unit to settle before
noting the angle.

Setting an alternate reference point allows you to set any angle to ZER . This new ZER is
now a reference point from which to take measurements. For instance, you may want a surface
that is actually 25° off absolute zero (horizontal) displayed as ZER so you can measure all
other angles from that benchmark. See the example below for Relative angle measurement:
1. Unit starts in absolute zero measurement mode (the icon “ABS” is visible). Put the inclinome-
ter on the surface that is actually 25° off the horizontal plane. The unit now reads 25°.
2. Press the ALTERNATE ZER button to change to relative measurement mode (the icon “ABS”
is no longer visible, the angle readout is now ZER ).
3. Put the inclinometer on the surface that is actually 60° off the hori-
zontal. The “35.0°” shown on the display is relative to the 25° off the
horizontal plane.

BATTERY INSTALLATION
(use lithium battery CR2032 3V or equivalent)
1. Back view of Digital Inclinometer.
Slide battery cover to the right
to remove.
2. Back view of Digital Inclinometer with
battery cover removed, exposing cop-
per battery connections. Tab A posi-
tive (+), strip B negative ( –).
3. Slide battery (lithium CR2032 3V or
equivalent) UNDER small copper tab
(A), push battery on top of long cop-
per strip (B) until battery snaps into
place. Make sure battery description
is facing up and that copper tab (A)
makes contact with battery. Replace
battery compartment cover by slipping
cover tab (C) in insertion hole (D).
This will ensure copper tab contact
with battery.
REPLACING BATTERY
1. Turn unit off. Remove battery com-
partment cover. Insert screwdriver or
paperclip into battery removal slot (E).
Battery pops out.
2. Follow step 3 from BATTERY
INSTALLATI N to replace
battery.
3. Slide battery compartment cover
in place by slipping cover tab (C)
in insertion hole (D) as illustrated.
4. Digital Inclinometer will have to be recalibrated after battery replacement.
SCREW-IN LEGS
Two screw-in legs are provided with the unit. Screw legs into bottom of unit as far
as possible. Legs ensure 2 points of contact for unlevel surface such as spine and
cervical spine.
