Q:
What would your design or feature "wish list" be for this product?
15 answers
Answers:
Improving of small sizes internal measurements, depth measurements and including SPC features built in with no need to connect to a PC. The use of the "step gage" feature should be more explained. I've met a lot of people which even don't know the existence of this measurement mode.
~AARON M., Senior Calibration Technician, HAIFA, ISRAEL
Precise digital caliper with: 1) hard, strong and stable material, 2) English and metric system ,with 3) long lasting batteries and that is 3) water/oil proof for working in environment with coolant (cutting oil) like with CNC machines.
~Engineer, Redmond, WA
Easy single hand operation, good repeatability and realistic resolution, clear digital display. A fiducial load indication would be good for consistency of measurements.
~Rob M, Technical Support, Birmingham, UK
More special design as standard for measuring face and I didn't find at any caliper the round depth gauge for caliper bigger then 200mm.
~MURARU C, Marketing/Sales, Bucharest, Roumania
Longer jaws that are less affected when measuring at tips. O.D. jaw surfaces closer to the beam. Laser calipers would be nice.
~Willy, Other, Renton, WA
Current designs are well established and serve their purpose, so my only wish would be for higher quality at a lower price.
~Tom R, Production Engineer, Sydney, Australia
Allow self tightening to a certain force. Temperature compensation. Make them specific to the material being measured.
~Paul A, Process Engineer, Montgomeryville, PA
More options on I.D. measurement (i.e. the ability to check retaining ring grooves and small hard to reach steps).
~Engineer, Gorham, ME
They are great multi functional instruments already. There are many models for many applications.
~Daniel Donckers, Calibration Inspector, Longueuil, Canada
Back lighting digital display w/longer batt. life. or possibly solar powered.
~BUTCH R, TRACTOR TRAILER MECHANIC, MARKHAM, IL
Switchable upside down displays for use on machining.
~Roy M, RSM Quality Services, Poole, UK
Memory and multiple readout ability.
~Chad N. Quality Assurance, SK Canada N, Quality Control, St. Brieux, Canada
Best non wearable measuring edges.
~Jaganathan Krishna Murthy, Technical support, Singapore, Singapore
Put a auto mode on them.
~LARRY L, Manufacturer, NEWARK, CA
Improved ease of use.
~Philip F, Engineering Consultant, Sunnyvale, CA

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of calipers?
14 answers
Answers:
For critical inspections perform a gauge R&R study to ensure that the combined measurement uncertainty is acceptably within the tolerance of the dimension being measured. Calipers may not be an accurate enough instrument for the job - you may need plug gauges or a micrometer.
~Tom R, Production Engineer, Sydney, Australia
Just because it discriminates to within 0.01mm doesn't mean it is accurate to 0.01mm. Always check that it zeros before using it. Protect and keep clean. Avoid extremes of temperature and unnecessary immersions.
~Roy M, RSM Quality Services, Poole, UK
To train themselves to make accurate measurements, especially internal ones by measuring artifacts with a known size. To use more digital calipers - the readings are faster and the possible errors are less.
~AARON M., Senior Calibration Technician, HAIFA, ISRAEL
Use a gauge block or standard to check you measuring touch/pressure as well as the accuracy of the tool. Be sure you are square, true and plumb with the object being measured.
~Willy, Other, Renton, WA
Do your research. Keep them clean and in the box when not in use. Check against a calibration standard very regularly.
~Paul A, Process Engineer, Montgomeryville, PA
Avoid simply accepting the last digit of the readout, don't confuse display resolution with accuracy.
~Rob M, Technical Support, Birmingham, UK
Persons who are not having the feeling during taking measurements are advised to practice .
~Jaganathan Krishna Murthy, Technical support, Singapore, Singapore
Don’t fall for cheap stuff. My grandma always said: I’m not so rich to buy cheap stuff.
~Engineer, Redmond, WA
Check that they remember the zero setting while turned off.
~Philip F, Engineering Consultant, Sunnyvale, CA
Electronic calipers are no more accurate than dial calipers.
~Engineering, Consulting, Cincinnati, OH
Spend a little extra to get a higher quality instrument.
~Chad N. Quality Assurance, SK Canada N, Quality Control, St. Brieux, Canada
Lower price - less quality in time and insigure results.
~MURARU C, Marketing/Sales, Bucharest, Roumania
Electo digital system.
~Nwaobiyebe L, Quality Control, PORT HARCOURT, NIGERIA
Always check zero.
~Engineer, Gorham, ME
