This is a typical operating sequence for learning. Your instrument model and approved SOP take precedence.
STAGE 1
Before you start
- 1Check the calibration status label.
- 2Clean the jaws so no powder or fragments remain.
- 3Select the correct units (N) and test settings for the product.
- Never test with powder on the jaws; it changes contact and gives wrong values.
STAGE 2
Testing
- 1Take the number of tablets stated in the procedure (often 10).
- 2Place each tablet in the same orientation, centred between the jaws.
- 3Start the test and record the breaking force.
- 4Remove fragments and clean the jaws between tablets.
- 5Report individual values, mean, minimum and maximum.
- Keep fingers clear of the jaws during the stroke.
STAGE 3
After testing
- 1Clean the jaws and the fragment tray
- 2Complete the usage log
