MAINTENANCE (Continued)
DIGITAL GAGE
Important
Do not mark the scale unit with an electric engraver or scratch
the scale.
Always use an SR44 battery (silver oxide cell)
If the scale will not be used for more than three months, remove
the battery and store it properly. Otherwise, leakage, if any, from
the battery may damage the unit.

Battery Installation and Origin Setting
Set the origin of the scale after installing the battery. Otherwise,
the error sign("E" at the least significant digit) may appear,
resulting in incorrect measurements.
1) To install the battery, remove the compartment lid and
install the SR44 battery with its positive side facing up. After
the battery is installed, set the origin.
2) To set the origin, move the slider to an area you wish to set
as your origin. Turn the power on. Hold the ORIGIN switch
down for more than one second. The "0.00" display
appears, indication Origin setting is complete. The origin
will be retained even if the power is turned off.
Incremental (INC) & Absolute (ABS) mode
The LCD will dispay measurements from the origin when turned on
(ABS mode). To set the origin see above. The display can be set
to zero at any desired position by pressing the ZERO/ABS switch.
INC indicator will apper in the display (INC mode), permitting
measurements from this zero point. To return to the ABS mode
hold the ZERO/ABS button form more than 2 seconds.
Error Symptoms & Remedies
 ERRC and display flickering: Occurs when the scale
surface is stained. Clean the scale surface and coat a thin
film of low viscosity oil to keep out moisture.
 E in the least significant digit: This occurs when the
slider is moved too quickly, but it does not affect the
measurement. If it stays on when the slider stops, the scale
surface is probably stained. If this is the case, take
remedies as for ERRC.
 B indication: Battery voltage is low. Replace the
battery as soon as possible.
Cleaning
Clean gage with CRC 3-36 Cleaning and Lubrication OIl. Wipe off
excess after cleaning. If CRC 3-36 is not available, use Denatured
Alcohol to clean, then apply light oil and wipe off excess.
