How to Handle Your Microbalance
Before you Start weighing, please observe the
following:
After plugging your balance into a wall outlet, make sure to al-
low for >2 hours' warmup.
Working with a microbalance requires a steady hand and a
smooth, uninterrupted technique.
Use forceps or other suitable Utensils to load your sample on
the pan.
Do a few trial weighing procedures before you begin with actual
weighing of your sample.
lf the weighing chamber has not been opened for a relatively
long period, it may have a temperature which is different from
that of the balance's surrounding environment. Therefore, as
soon as you open the weighing chamber, a change in the tem-
perature will inevitably occur. This change in temperature may
show up as a change in the weight readout. In this case, we
recommend that before you begin with an actual repetitive
weighing procedure you open and dose the weighing chamber
at the same rate as you will be doing during such a procedure.
Carefully place you sample on the pan and, if necessary, re-
move it along with the pan. After the weighing chamber is
closed, the weight readout, as a rule, will stabilize after 30 sec.
at the latest.
The accuracy of the resulting weight readouts will increase as
the degree of consistency is increased for successive weighing
procedures.
