The instruments are calibrated at 20 Degree Celsius, however in practical use sometimes they are used at above 35 Degree Celsius , what compensation factor is to be calculated?
The standard temp. of calibration is 20 degree Celsius but if the master equipment and jobs under test are of the same material and are stabilized at the same temp. then the difference in measurement is almost negligible.
If we shift our surface plate from one place to another does it need recalibration?
No, If the surface plate is placed at the same supports where is was originally levelled /placed there will be no change in flatness upto the size of 1000x2000mm.
Can we calibrate a surface plate with single precision level/Electronic level?
No, Precisely we can not calibrate because sagging of the floor and other Outside vibrations will introduce errors in precision calibration. The sagging of Floor upto 10 Micron per meter have been observed in industries.
How does Bagson Calibration Lab Controls this sagging effect?
We at Bagson Calibration Lab. use precision electronic level in pair, which gives the readings in differential mode hence eliminating all these kind of errors.
Can we use 0.1 Micron single probe for the calibration for Slip Gauge?
No, Slip Gauges of 0, 1 and 2 grades can not be calibrated with single probe, As because the air film and bend in slip gauge introduces error. How ever with 0.1 micron double probe method and rigid stand the grade 2 Slips gauge can be Calibrated.
Which master equipment is required for the calibration of slip gauges
Rigid Slip gauge calibrator with double probes of least count of 0.01micron And reference slip gauge set of grade 00 or grade K are required for the calibration of slip gauges.
Is it mandatory to level the surface plate precisely during use?
It is recommended to level the surface plate but in most of the actual uses it is not Mandatory for small plates upto 1000 x 2000 mm.
