NO
NO
Prior to weighing or in the case of ambient condition changes, it is necessary to carry out balance
adjustment.
• Prior to the measurement, it is recommended to load the weighing pan, several times, with
mass close to the maximum capacity. In the case of instruments offering two reading units (d),
the initial load of the weighing pan depends on the reading unit value.
Example: For AS 82/220 R2 balances with d
1
= 0.01 mg and d
2
=0.1 mg load the weighing pan
as follows: 50 g weight for measurements with d
1
=0.01 mg and 200 g weight for measurements
with d
2
=0.1 mg.
• Make sure that the unloaded balance indicates “precise zero” ( pictogram) and check
whether the measurement is stable (
pictogram), if not, press /Delete button.
• Press UNITS key, to set a measuring unit.
• Place weighed object on the weighing pan and read result only on measurement result
stabilization,
• Mass indication of a load placed on the weighing pan can be tared multiple number of times by
pressing →T
←
/Insert (pay CAUTION not to exceed maximal capacity of a balance by applying
multiple tare function).
The balance shall stay plugged to the mains in between measurement series. It is recommended to
switch off the balance display by pressing ON/OFF button. On repeated ON/OFF button pressing, the
balance is ready for operation and carrying out the following measurements.
11.2.2. Balance Zeroing
Zeroing is a function allowing to zero mass indication. In order to zero mass indication, press
button. Mass indication of zero value shall be displayed together with precise zero
and stability
markers.
Zeroing process is an equivalent for determining new zero point, recognized by the balance as
precise zero. Zeroing is possible only for stable status of display indication.
CAUTION!
Zeroing the display indication is possible only within ±2% range of instrument’s maximum capacity. If the
zeroed value is above ±2% of the maximum capacity, then the software indicates an error message, Err2.
11.2.3. Balance Taring
Taring is a function allowing to determine net weight of a measured object. In order to determine net
weight of the object, place object’s container (packaging) on the weighing pan, and on stabilization of
measurement result press
key. The display indicates mass equal zero and symbols: Net and
. On taking off the weighed load and its packaging from the weighing pan, the display indicates
sum of total tared mass with minus sign.
The software enables assigning tare value to a database-stored product. Using this option, the
software automatically uploads data on tare value for a particular product upon its selection from the
database.
CAUTION!
Taring negative values is impossible. On taring negative values the balance responds with an error message,
Err3. In such case, zero balance indication and repeat taring procedure.
