OPERATING INSTRUCTIONS
Automatic OFF
The micrometer will turn off (the display will go blank) after 20 minutes of no spindle movement. Any movement of the
spindle will activate the display with no loss of position reading.
HOLD Button
One button push will freeze the display and the word “HOLD” will appear. A second push will update the display to the
current position reading.
SHIFT/SET Button
This is the button that gives great versatility to this tool. Pressing this button will change the function of this button to
SET
— it will change the function of the
ZERO/ABS
button to
PRESET
, and it will change the function of the
IN/mm
button to
LIMITS
.
Cautions on Use
•
Avoid dropping the micrometer.
•
Avoid extreme temperatures, direct sunlight or below freezing for extended periods.
•
To prevent sluggish or sticky movement clean the spindle.
•
Avoid shocks to the spindle faces. Frequently clean the spindle faces using a dry cloth or a
chamois.
•
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 using anything that might damage the buttons when pressing the buttons.
•
It is important to wipe the micrometer with a lint-free cloth after exposure to moisture.
•
Do not use aggressive solvents to clean the plastic components.
•
Do not store the instrument in areas of extreme temperature.
•
The spindle is designed not to be removed from the tool and should not be rotated more than
one revolution past the limits of its measuring range as this may result in damage to the tool.
•
Do not mark the tool with an electric marking pen as this may damage the tool.
INTRODUCTION
Starrett Electronic Digital Micrometers are designed for easy use and allow output to SPC
(Statistical Process Control) printers, processors, and computers.
Resolution is .00005" or 0.001mm in both the regular and “ME” series, except it is .0001" in both the regular and
“ME” No. 733.1 series over 4"
Accuracy is ±.0001 or ± 0.003 mm in the 0-1" (0-25 mm) range and as good as setting to a gage above that
because the mechanical and electronic components are the same in all ranges.
Installation of Battery
Before you install the battery that comes with the Micrometer see “New battery, Startup Sequence” page 4 and
then
“Battery Replacement” on page 7.
