How to check if the digital caliper is working properly?

 draft post

 

 Checking if a digital caliper is working properly involves verifying its zero point, ensuring the sliding mechanism is smooth, checking for physical damage, and testing its accuracy against a known standard. 
Here is a step-by-step guide to verify your digital caliper:
1. Preliminary Cleaning and Inspection
Clean the jaws: Wipe the measuring faces with a clean, dry lint-free cloth or paper to remove oil, dust, or residue that can cause inaccurate readings.
Check for damage: Inspect the jaws for nicks, burrs, or scratches that may affect accuracy.
Check smooth operation: Move the slider along the entire length of the beam to ensure it slides smoothly without binding or rattling. 
2. Zero-Point Calibration Check
Close the jaws: Completely close the outside measuring jaws.
Check for light: Hold the closed jaws up to a light source. Ideally, no light should be visible between the jaws. If you see light, the jaws may be warped or dirty.
Zero the screen: Press the "Zero" or "On/Zero" button. The screen should read 0.00 mm (or 0.0000 in).
Test repeatability: Open and close the jaws several times. The display should consistently return to 0.00. 
3. Accuracy Check (Known Standards)
To verify that the caliper is measuring accurately across its range, test it against a known standard: 
Use Gauge Blocks: Measure a calibration gauge block (or a set of blocks) of a known dimension (e.g., 25mm, 50mm, 100mm).
Check at different points: Measure the standard at different positions (near the beam and near the tip of the jaws) to ensure consistent readings.
Compare to standards: Verify the readings against the known size of the gauge block. 
4. Other Functional Checks
Check for parallelism: If the jaws are not perfectly parallel, measurements will be inaccurate. Using a gage pin can help verify this.
Check Depth and Step Functions: Use the depth bar to measure a known hole depth, and the step function to measure a known step, ensuring the tool is used on a stable, flat surface.
Check Battery/Electronics: If the display is flickering, fading, or jumping in numbers, replace the battery. 
Common Reasons for Inaccurate Readings:
Dirty jaws: Even microscopic debris can affect the 0.01mm resolution.
Excessive Force: Applying too much pressure when measuring can cause the tool to flex, resulting in an incorrect, lower reading.
Temperature Variations: Extreme temperatures can affect the metal and digital sensors.
Dropping: A dropped caliper can result in warped jaws or damaged internal sensors, requiring professional repair.

The purpose of the Electrostatic Discharge (ESD) Kit is to preserve the inherent reliability and quality of sensitive electronic components handled during maintenance. The kit should be used as directed when handling ESD sensitive components.

1. If applicable, assemble the kit:

   1. Place the static dissipative work surface mat on a flat surface in close proximity to the machine or the component.
      
      
      
      

   2. Connect the snap end of the green grounding cord to the snap on the static dissipative work surface mat. Connect the male end (plug) to the frame.
      
      
      
      
      
      
      
      

   3. Connect the small snap end of the blue cord to the top snap on the green grounding cord.
      
      
      
      

   4. Connect the small snap end of the blue cord to the snap on the adjustable cloth wrist strap.
      
      
      
      

   5. Place the adjustable wrist strap on the wrist.
      
      
      
      

2. The ESD sensitive components can now be handled without causing any ESD related damage. If applicable, place all of the components removed from the machine onto the static dissipative work surface mat.

3. If applicable, new replacement components, as well as defective components, should be handled during unpacking and repacking using the ESD Kit. During transfer from or to the packing material or container, the component should be placed on the static dissipative work surface mat.
