Digital caliper

  • Diagrammatic Structure
  1. Internal jaws   2. Inch/mm key     3. Locking screw   4.LCD display     5. Depth measuring blade   6. Scale     7. Battery cover     8. “Zero” key 9. “on/off” key       10. External jaws
  • Characteristics & Function
  1. LCD readout display, with four measuring functions of inner diameter, outer diameter, depth and step.
  2. It can work in both direct measurement and relative measurement.
  3. It is made of hardened stainless steel material with advanced technology and excellent manufacturing.

4.Its complete sealed module structure, provides it with certain resistance to water, oil and coolant.

  1. USB interface allows data to be outputted to a printer or computer for data processing and printing.

 

  • Usage Direction
  1. Put the specially equipped battery cover key in the middle of the battery covergroove, rotate counterclockwise, open the battery cover, and install/replace battery, then rotate clockwise to lock the battery cover.
  2. When the LCD readout displays small fonts “in” , it is under inch system.
  3. Mm/in: it is a Metric and inch conversion key. Press this key for mm/in system
  4. ZERO: Zero Setting key. It can set-zero in any position within the measuring range.
  5. ON/OFF: power on/off key.
  6. Before usage, loosen the fastening screws on caliper frame, and pull the caliper frame open gently, then use a clean soft cloth to wipe the measuring surface and the guiding surface clean.
  7. Check the “zero” position: Push the caliper frame gently until the two measuring jaw surfaces are close, so the LCD readout displays “zero”, otherwise, press the “zero” key to set- zero.
  8. When measuring outside diameter,fix theoutside measuring surfacesclose to the measured workpiece.
  9. When measuring inside diameter, put the measuring jaws under measuring in the diameter direction,don’t lean.
  10. When measuring the depth, put the depth measuring blade vertically with the measured workpiece’s bottom surface.
  11. Direct measurement: use the caliper to measure the workpiece directly, and the LCD readout displays the measuring value
  12. Relative measurement:set “zero” when measuring the standard workpiece/sample, then measure the workpiece, the LCD readout displays the relative measuring value to the standard workpiece/sample.

 

  • Attentions
  1. Avoid exposure to the places of high dust, avoid exposure to sunlight ultraviolet radiation and high temperature
  2. When pulling the caliper frame open, do it gently, do not drop or crash it.
  3. Clean the measuring surface with gasoline or alcohol, while keep any liquid away from electronic components and the measuring blade upper surface.
  4. The usage and test environmental relative humidity ≤80﹪.

 

 

 

  • Troubleshooting
Common fault Possible reason Troubleshooting
Readouts jump or no readouts Poor battery contacts or dead battery 1.Check the inner battery contact2.Replace battery
Readouts display irregularly Caliper under damp and moisture situation Clean the measuring blade upper surface with gauze or open it and clean
