5.4 For Stable Measurement in Semi-micro Range
(CAUW-D series only)
The small range (semi-micro range, minimum display 0.01mg) of CAUW-D series dual
range
balances produces excellent response and stability. However, weighing in the 0.01mg range
is generally more subject to the environment and how measurements are performed
compared to the 0.1mg range.
When using the small range of CAUW-D series, observe the following instructions in order to
obtain the best result.
Avoid air current from the air conditioner. When the air conditioner is in operation,
the temperature of the air current from it has a large difference from the room temperature.
Air current and presence of different temperatures both make the measurement unstable.
The temperature of the balance does not change as fast as the room temperature. Changing
room temperature prior to measurement causes temperature difference remaining for a long
period. Even without direct blow of air current, contact of air of different temperatures
generate air convection in the weighing chamber and result in unstable display.
x Leave the glass doors open while not in use. This prevents temperature gap between
weighing chamber and ambience.
