Parameters
Adjustment
a)
INTIAL
POSITION
To save time adjust the running
distance of Jaw near to approximate Diameter of tablet.
Increase or Decrease in distance.
b) SLOW LIMIT
For the precise
results force is being applied very slowly on tablet.
This limit
should be adjusted slightly more (+3mm) than approximate diameter of tablet.
c)
FORCE
UNITS
Hardness can measure
and display in Kg, N or lb units.
d)
FORCE
LIMIT
For
safety & efficacy value of force applied can be adjusted nearly above to
the breaking force.
Range 0 – 50 kg.
0 – 110 lbs.
0 – 490 N
e)
NO
OF TABLETS
Test size
ranging from 0 – 20 tablets can be adjusted.

· Place the tablet on S.S stage against fixed jaw.
· Press Start.
· On initial position the moving Jaw will stay for 5
seconds during this interval
· Clean the stage will brush throwing the pieces of
tablets down in fragments collector.
· Place the next tablet on stage at same angle.
· Place the number of tablets selected for test one by
one as mentioned in Step (iii)

Moving Jaw will
move fastly till the adjusted Slow Limit & than slowly, apply
the force on tablet.
At the time of
breaking point. The tablet will crash. Reading of breaking force will

After few
seconds moving Jaw will return and stop at adjusted INITIAL
POISTION. Where it will stay approximately for 5 seconds and than it
will move forward for next measurement.
After completion of interval moving
Jaw will start automatically to break the tablet.
After breaking
of each tablet smartly
i) Clean the
stage will brush throwing the pieces of tablets down in fragments collector.
ii) Place the
next tablet on stage at same angle.
Printer will
