Calibration is recommended once per year to ensure proper
function and accuracy of the 8400K.
Metrology labs can provide a NIST traceable certificate of calibration
(with measurement data) using this procedure.
A
.
EQUIPMENT
One set of gage blocks, current and traceable to N.I.S.T.
B. INSTRUCTIONS
1. Slide one gage block lengthwise across the top of the other,
creating a step at the end. (The blocks "ring" together with this
method.)
2. Place micrometer over the “step” and focus on the top of the
upper gage block. Position so approx. one-half of the viewing
field is on upper block.
3. Set digital display to “0.0000”
4.
Focus on lower gage block. Display should show thickness of
upper block.
Suggested gage block sizes:
BOTTOM 0.1000”
TOP
0.0625” , 0.2000” , 0.5000” , 1.0000”.
(Use 4X Objective for 0.2500” and above.)
