5. FUNCTIONS OF THE BALANCE

Tare function

Tare function is used when a substance contained in a recipient is needed to be weight;

for example liquids or solid reagents contained in a beaker to prepare a solution. For this
function, proceed as follows:

Put the empty recipient on the pan and press Tare

(2.4)

, “0.00 g” will be displayed.

When the stabilization simbol “o” is displayed the balance is tared and ready to weight
the substance.

NOTE: The balance presents a tare range the same as its maximum capacity. This maxi-

mum must be taken into account since if the maximum capacity is tared nothing more
could be weighted. (For example: if 450 g are tared in a balance with a maximum capacity
of 500 g, only 50 g more will be weighted).

Calibration function

Before starting using the balance and whenever observing important variations in weig-

hing or not correct weighings, balance should be calibrated. Some factors such as varia-
tion of gravity depending on latitude, change of working place as well as an inappropria-
te use of the equipment lead to the necessity of recalibrate the balance.

Important!! do not move the balance during calibration

1. Turn the balance on by pressing On/Off

(2.5)

and make sure that there is nothing on

the pan

(1.1)

2. Press Tare

(2.4)

and when “0.00 g” is displayed press Cal

(2.1)

. “CAL” is displayed

and then the weight of the calibration weight required.
