Auto-Calibration (For Models Fv-120C And Fv-220C); Manual Calibration (For Models Fv-120 And Fv-220) - Gram FV 120 Serie Manual De Utilización

calibrating the balance. That means whenever we move a balance from one
area to another, we have to put a standard calibration weight (100.0000g
for example) on the weighing pan and tell the balance here this weight is
100.0000g. Please make it as a reference to other weighings. This is the
calibration of balance.
There are two ways to calibrate the analytical balance.

Auto-calibration (For models FV-120C and FV-220C)

• Plug in and pre-warm the balance at least 30 minutes.
• Turn on the balance.
• The balance will be calibrated automatically after several minutes and
whenever the environment temperature changes out of a definite limit
over 2ºC or it Works out of the time limit over two hours.
Note: If "CAL-no" is displayed:
• Check if there is any object on the pan or the build-in calibration weight is
loaded down onto the weighing mechanism while calibration.
• Remove the objects from the pan or raise up the build-in calibration weight
from the weighing mechanism.
• Press the
up when it is on the weighing mechanism.

Manual calibration (For models FV-120 and FV-220)

In this mode, the parameter should be set to C1-01.
