: Battery voltage low.
: Data output is transmitting.
4. Operation
Two ways of pressing the keys are used in the following illustrations:
(1) Press and release; (2) Press and hold (2 sec. or more).
4.1 ON/OFF•••SET key:
Press and release: Power on/off.
Press and hold (2 sec. or more): Datum setting for absolute measurement; "Set" sign displayed on LCD.
Origin of metric is 0, 25, 50, 75 ••• 275mm. Origin of inch is 0, 1", 2", 3" ••• 11".
Sets datum automatically after battery reset.
4.2 ABS/INC•••UNIT key:
Press and release: Absolute and relative measuring mode conversion; "INC" sign displayed on LCD in relative measuring
mode. "ABS" sign displayed on LCD in absolute measuring mode.
Press and hold (2 sec. or more): Metric/Inch conversion; "in" sign displayed on LCD for inch, otherwise mm.
5. Power
• A silver oxide cell SR44 is inserted into the back of the instrument with the positive pole outward . Replace the battery
when the display data is dim or the " " sign is displayed in the upper left of the LCD.
• If not used for approximately five minutes, the power will auto-off. The micrometer will turn on by pressing "ON/
OFF•••SET" key or turning the spindle. Power off the micrometer by pressing "ON/OFF•••SET" key to save the battery.
6. Specifications
Measuring force: 5 ~ 10N Power consumption: ≤ 20 µ A
Operating temperature: 0 ~ 40˚C Storage temperature: -20 ~ 60˚C
7. Data Output
1200 Baud, no parity, 7 data bits, 2 stop bits, no flow control.
8. Precautions
• Do not subject the instrument to blows or knocks. Do not drop it or apply excessive force.
• Do not disassemble the instrument.
• Do not press the keys with a pointed object.
• Do not use or store the instrument under direct sunlight, or in an excessively hot or cold area.
• Do not use the instrument near strong magnetic fields and high voltages.
• Use a soft cloth or a cotton swab that is dry to clean the instrument. Do not use organic solvent such as acetone or
benzene. Alcohol may be used.
• Wipe the measuring faces of the instrument before using it.
• Remove the battery if the instrument is not used for a long period of time.
