CAUTIONS ON USE
1. Avoid dropping the Indicator.
2. Avoid extreme temperatures, direct sunlight or
below freezing for extended periods.
3. Avoid shocks to the contact point and spindle. Do
not apply any radial force to the spindle.
4. If the indicator is stem-mounted, protect the
indicator from being struck or bumped to prevent
stem/case mechanical alignment damage.
5. Do not over-tighten the mounting mechanism and
use clamp mounting rather then set screws, if
possible, to prevent damage to the spindle.
6. Frequently clean the spindle using a dry cloth or a
chamois to prevent sluggish or sticky movement.
Isopropyl alcohol may be used to remove gummy
deposits on metallic parts. Do not apply any type
of lubricant to the spindle and do not use solvents.
• Avoid any disassembly or modification of
the indicator, other than what is outlined in
"Accessories" on page 27
7. Avoid using anything that might damage the
buttons when pressing the buttons.
8. Use the appropriate gage stand or indicator holder
for the job intended.

OPERATING INSTRUCTIONS
1. First read the "New battery, Startup Sequence"
section below, and the "Zero Sequence" on the
next page 11.
2. Install the batteries that came with the indicator.
Refer to "Battery Drawer Removal" and "Battery
Replacement" on pages 25, 26.
3. Lightly clean the contact point.
4. Fasten the indicator onto the appropriate holding device.
5. You can turn the indicator on by either pressing
the ON/OFF button or moving the spindle.
6. If applicable, pick the unit of measure, inch or
millimeter by pressing the IN/mm button.
Note; standard metric indicators do not have this
function available, however this will be available
on the ME series of indicators.
7. Place the indicator perpendicular to the reference
surface being measured.Allow enough movement
to be able to take a higher or lower measurement.
8. Reset the display by pressing the ZERO Button.
9. Lift the spindle to remove the reference surface,
and carefully place the piece to be measured under
the spindle making contact with the surface. The
value measured on the display will be the difference
between the reference and the measured piece.
10. The indicator can be turned off by pressing and
holding the ON/OFF button for 3 seconds.
Note: the unit will automatically enter sleep mode in
30 minutes, if left unattended.

NEW BATTERY, STARTUP SEQUENCE
1. Each time you put in a new set of batteries, the
indicator will go through a startup sequence. See
"Battery Installation and Replacement" on pages 25,
26.At the end of the sequence you will need to move
the spindle to initialize the measurement system.
2. When the indicator comes on after the batteries
have been changed, the display will go through a
series of changes Fig.1-5.
Note: The information displayed here will change
depending on the indicator you are using and is
shown, to give you an idea of what to expect when
changing the battery.

3. When "Cal" is displayed, move the plunger slowly
in and out, until the display changes to show the
indicator measuring. This movement will calibrate
the indicator.
4. This feature will happen each time the battery
is replaced.
5. If you don't move the spindle, "Cal" will stay on the
display for only 10 seconds and the display will go
blank. To return to "Cal" mode move the spindle or
quickly press the on/off button.
6. If you move the spindle to fast it will take longer for
the tool to initialize.

NEW ZERO SEQUENCE
7. After speed mode is completed press the ZERO/
ABS button and the display will show a dashed line
as seen in Fig.6 below. The line will incrementally
disappear from left to right Fig.7; this is a visual
clue on how long you should wait for the tool to zero
out. Make sure not to move the spindle during that
time. This will happen each time the tool is zeroed,
takes about a second to complete.
8. Fig.7 shows a representation of how the display will
look when the sequence is completed.
