Digital outside micrometer 0-25mm (YT-72305)

Micrometer 0-25mm with digital display

• measuring range: 0 - 25 mm
• resolution: 0.001 mm / 0.00005 inches
• accuracy: ±0.002 mm / ±0.0001 inch
• measuring force: 5 - 10 N
• display : liquid crystal LCD display
• current consumption: ? 35 ?a
• power supply: one 1.55V silver battery, type SR44
• operating temperature: 5O^OC - 40O^OC / 41OF - 104OF
• storage temperature: - 20O^OC - 60O^OC / -4OF ÷ 140OC
• humidity effects: negligible below 80% relative humidity
• to take precise measurements and easy readings from 0 to 25 mm

Preparation for operation:

• Clean the measuring surfaces and the guide. Use a cotton cloth for this purpose. Do not use solvents or acids
• check the zero position for this purpose, bring the measuring surfaces into contact by turning only with the friction clutch knob. Then press and hold for about 2 seconds the button described ON/OFF---SET", until the indication is zeroed
• check that all buttons, switches and display are working properly

Basic measurement methods:

1. Absolute measurement

• loosen the locking clamp
• switch on the device by pressing the "ON "button
• select the measurement unit by pressing and holding the "ABS/INC---UNIT "button for about 2 seconds
.
• each time the measurement result will alternately be displayed in inches or millimeters
• the result in inches is described by the "in" symbol shown on the display screen
• press the "ABS/INC---UNIT" button until the "ABS" symbol appears on the display
• .spread the measuring surfaces to a distance slightly larger than the object to be measured
• then turn the stylus knob to roughly adjust, then continue tightening by turning the friction clutch knob
• stop tightening when the clutch engages
• read the measurement result from the display

2. Relative measurement

• the measurement principle corresponds to that described above, but the relative measurement is used to compare two dimensions
• .when the "ABS/INC---UNIT" button is pressed, the indication will be reset to zero, and the display will show the symbol "INC"
• after measuring again, the difference in dimensions can be read

The micrometer is equipped with a steel ball in a rubber mount for mounting on the measuring surface of the micrometer. It facilitates the measurement of parts with a small surface area. After attaching it, the indication should be zeroed according to the procedure described above.

Note!

Note: It is recommended to mount the measured element or micrometer before starting the measurement. This will allow you to achieve the highest measurement accuracy.

Please note

It is also recommended that you take several measurements so as to obtain an arithmetic average of the results.
