LCD digital display sandblasting and shot peening surface roughness testing with anchor pattern instrument

one.Technical Specifications:

two.Function:

1. Switch/Reset button: Press the switch/reset button (ON/0) to turn on the power. Short press this button to reset to zero to enter measurement mode. Press and hold the key to shut down.

2. Metric to English conversion key (mm/in) key: can convert between millimeters and inches

3. Use of function keys (M)

A: HOLD: Short press this key to keep the measured data unchanged, press it again to switch to normal settings

B: Quick value tracking: Press and hold this button until "MAX" is displayed. During testing, the displayed value is the zuida value during the measurement process. Press this button again to reset to the current measurement value and start a new measurement. After using this function, long press this button to display MIN, long press again to display △, and then long press this button again. The top line of the display screen will disappear, indicating that it has entered the normal measurement state

C: Quickly follow the minimum value: Press and hold this key until "MIN" is displayed. During testing, the displayed value is the minimum value during the measurement process. After using this function, long press this key to display △, and then long press this key again. The top row of the display screen will disappear, indicating that it has entered the normal measurement state

D: Quick follow-up difference (△): In test mode, press and hold the M key repeatedly until "△" is displayed, and the displayed value will automatically reset to zero. When measuring, the displayed value △=MAX-MIN. After using this function, long press this button, and the top line of the display screen will disappear, indicating that it has entered the normal measurement state

4.Tolerance setting key（TOL: Move the roughness meter to the limit value of the measured workpiece (high or low), long press the tolerance setting button, and the TOL SET will be displayed at the bottom left of the screen, indicating that this limit value has been set; Move the roughness gauge to the (high or low) limit value again, long press the tolerance setting button, and TOL will be displayed in the lower left corner of the screen. This limit value setting is complete. The system automatically enters the tolerance judgment state. During the measurement process, if the measured value is before the high and low limit values, the screen displays GO. If the measured value exceeds the high and low limit values, the screen displays NO GO and flashes. To exit the tolerance judgment state, press the setting button briefly. If you want to return to the tolerance measurement state set last time, press the tolerance setting button briefly.

5th JudgeMeasurement key（ABS: The default state of the instrument is the relative measurement state, and REL is displayed in the lower right corner of the screen. Long press the button to display SET at the bottom of the screen, and the screen number will flash. Short press the switch/reset button, and this number can be changed from 0-9 in sequence. After selecting the appropriate number, short press the button to enter the next digit setting. The maximum value is 99.99. After setting is complete, long press the button, and ABS will be displayed at the bottom of the screen. The number will no longer flash, and the measurement mode will be entered. If you want to cancel the juedui measurement status, press the switch/reset button briefly.

three.Measurement method:

1. Press the power button to turn on the device

2. Select the measurement unit mm/inch,

3. Press the instrument touch pin steadily onto the calibration glass plate, press the calibration button, and calibrate multiple times until the screen displays "0" as the standard

4. Place the instrument on the metal surface after sandblasting and press it steadily. Do not pull horizontally on the measuring surface.

5. Read and record the distance between the peak and valley of the sandblasted surface, that is, the surface roughness.

6. According to the standard requirements, measure 10 times on the sandblasted surface and record the average value of the 10 measurements.

4 Notes:

This instrument belongs to precision instruments and should be prevented from impact and falling to avoid affecting accuracy

2 should avoid the infiltration of water, oil, dust, etc

3 can be wiped with cleaning, do not use organic solvents such as acetone

After use, please turn off the power to extend the battery life. If not used for a long time, the battery should be removed.
