MEASURE GAPS: Use this Feeler Gauge when you need to quickly and easily measure gap widths.

USER FRIENDLY: The edge of the feeler gauge is steel and polished.

METAL TEXTURE: Its full of bright metal texture specially treated, smooth and doesnt hurt your hand.

USAGE METHOD:

(1) Wipe the measuring surface of the feeler gauge with a clean cloth. Do not measure when the feeler gauge is stained with oil or metal chips, otherwise the accuracy of the measurement results will be affected.

(2) Insert the feeler gauge into the measured gap, pull the feeler gauge back and forth, and feel a slight resistance, indicating that the gap value is close to the value marked on the feeler gauge; If the resistance is too large or too small when pulling, the clearance value is less than or greater than the value marked on the feeler gauge.

(3) When measuring and adjusting the clearance, first select the feeler gauge that meets the clearance regulations and insert it into the measured clearance, then pull the feeler gauge while adjusting until a slight resistance is felt. At this time, the value marked by the feeler gauge is the measured clearance value.

Feeler gauge, also known as micrometer or thickness gauge, is one of the measuring instruments used to check the gap. The cross section is a right triangle, and there is a scale on the inclined edge. The length of the short edge is directly expressed on the inclined edge by using the acute angle, so that the size of the seam can be directly read out.

Before using the feeler gauge, the dirt and dust on the feeler gauge and workpiece must be removed. When in use, one or several pieces can be overlapped and inserted into the gap.

Tips:

(1) Before using the caliper, confirm whether it has been calibrated and within the validity period of calibration.

(2) It is not recommended to bend the feeler gauge violently during measurement, or insert the feeler gauge into the tested gap with a large force, otherwise the accuracy of the measuring surface of the feeler gauge or the surface of parts will be damaged.

(3) The number of feeler gauge pieces shall be selected according to the clearance of the joint surface.

(4) High temperature workpieces cannot be measured.

(5) Pay attention to the correct method when using the feeler gauge (the measured gap must be perpendicular to the measured surface, and the measured fault difference must be leveled).

(6) When reading, you can read directly according to the value marked on the plug scale.

(7) Regular maintenance is recommended.

(8) After use, the feeler gauge shall be wiped clean and coated with a layer of industrial vaseline to prevent rust.

(9) When storing, do not put the feeler gauge under heavy objects to avoid damaging the feeler gauge.
