1 Installation instructions
WARNING:
Please carefully read these installation and use instructions before you begin using
your new balance. The product’s safety and accuracy cannot be guaranteed if the
instrument is used in a way that is different from that recommended in this manual.
DO NOT DISCARD THE ORIGINAL PACKAGING MATERIAL. THIS PACKAGING MUST BE
USED IF THE BALANCE NEEDS TO BE RETURNED FOR SERVICE.
▪Remove the balance and its calibration weight (if supplied) from the carton and check for any
visible damage to the instrument.
▪Do not install the balance in environments in which there are drafts, strong temperature
changes, or vibrations.
▪Do not use the balance in potentially explosive environments.
▪The humidity of the environment where the balance is used must be between 45% and
75%.
ATTENTION
For models with internal calibration: remove the protection screw in the
left lower part of the balance (see Section 5)
▪Place the weigh pan support and weigh pan on the balance (see page 6).
▪Level the balance by adjusting the front feet. The leveling bubble will indicate that the
balance is leveled properly.

5
▪Connect the power supply to the power inlet at the back of the balance (see Section 5).
▪Connect the power supply to a nearby outlet, which must be easily accessible. Press the
power button on the right side of the control panel to power on the balance.
▪Balance Warm-up:
▪It is necessary to allow the balance to equilibrate to ambient conditions before use.
Wait at least 8 hours after initially plugging in the analytical balance (0.0001g)
Then calibrate the balance as described in Section 7.
It is strongly suggested not to disconnect power cord from the balance to turn it
off. Use the ON/OFF button to put the balance into stand-by mode when not in
use.
▪Calibrate the balance every time that it is moved to another location.
▪Periodically check the balance’s calibration.
▪Do not drop objects of an excessive weight on the balance weigh pan, as doing so may
damage to the weigh cell mechanism.
▪Service should be carried out by trained personnel, and spare parts used must be original.
Contact your distributor or Accuris Instruments for service.
2 Storage conditions
▪Storage temperature +5 °C to +40°C
▪Storage humidity 45% - 75%.
▪Keep the original balance packaging in case the instrument needs to be shipped for
servicing; disconnect all cables and any accessories to prevent unnecessary damage.
▪Do not expose the balance to extreme temperatures and humidity unnecessarily, and avoid
violent shocks and vibration.

6.1 Stand By
From the “STAND BY” state:
▪Press the ON/OFF button to bring the balance to working condition.
▪Press the ON/OFF button again to return to the “STAND BY” state.
6.2 Simple weighing
Place the sample to be weighed on the plate and read the value of the weight on the display as
soon as the asterisk stability symbol ж appears.
7 Calibration
The Accuris Analytical Balance carries out mass measurements using gravity (g). Differences in
geographical regions and altitudes will affect the gravitational acceleration (g).
The balance must therefore be adapted to specific environmental conditions by calibrating to
obtain accurate measurements.
7.1 Balances with external calibration
7.1.1 External calibration
The calibration is carried out through the CAL button.
1. Press the CAL button with the plate unloaded; the word CAL will be displayed.

2. When the value of the calibration weight begins to flash, load the weight indicated by the
display on the plate.
3. The display will stop flashing, indicating the value of the calibration weight with the stability
indicator on.
Once the calibration has been carried out, the calibrated weight will be displayed with the
indication of the current unit of measurement.
4. Remove the calibration weight.
The balance is ready for weighing operations.
NOTE: an error message will be displayed if there is any interference during the calibration process. To
interrupt the calibration process, press the ON/OFF button while the calibration weight indication flashes.
It is also possible to calibrate the balance with a calibration weight greater than the pre-set
calibration weight:
1. Press and hold the CAL button with the weigh pan empty until the beeping stops, and then
release the button. The word “-CAL-“is be shown on the display, followed by the word
“LOAD”, flashing.

2. Load a weight that is equal to or greater than the pre-set calibration weight on the plate; the
balance will recognize a weight that is equal to or greater than the calibration weight as valid
provided that it is a whole weight with respect to the most significant figure of the calibration
weight.
E.G.: if the calibration weight is 200 g, it will be possible to calibrate the balance with values
that go from 200g, 300g, 400g up to the upper capacity limit of the balance.
The word “LOAD” on the display will stop flashing; once the calibration has been carried out,
the value of the weight used will be displayed.
3. Remove the calibration weight; the balance is ready for weighing operations.
NOTE: an error message will be displayed if there is some interference during the calibration process. To
interrupt the calibration process, press the ON/OFF button while the calibration weight indication flashes.
7.2 Balances with internal calibration
7.2.1 Internal calibration
In these models the calibration is carried out through an internal automatic system:
1. Press the CAL button with the weigh pan empty.
The display will show the message “CAL” and the balance’s calibration will be carried out
automatically.

2. At the end of the calibration, the balance will return to normal weighing conditions.
If the calibration is not completed due to vibrations or drafts, the message “CAL bUT” will be
displayed. Press the CAL button again, and if the problem persists, select external calibration
and contact the supplier.
To switch the calibration mode in these models to external calibration, see section 9.12.1
7.3 Verification
General introduction:
According to EU directive 90/384/EEC balances must be verified if they are used for legally
controlled applications:
a) For commercial transactions if the price of goods is determined by weighing.
b) For the production of medicines in pharmacies as well as for analyses in the
medical and pharmaceutical laboratory.
c) For official purposes.
d) For manufacturing final packages.
For any questions about requirements, please contact your local standards office.
Verification instructions
An EU type approval exists for balances described in their technical data as
verifiable. If a balance is used where obligation to verify exists as described above, it
must verified and re-verified in regular intervals.
Re-verification of a balance is carried out according to the respective national
regulations. The legal regulation of the country where the balance is used must be observed!
After verification the balance is sealed at the indicated positions.

Verification of the balance is invalid without the "seal".
Balances with a verification requirement must be taken out of operation if:
•The weighing result of the balance is outside the error limit.
Therefore, in regular intervals load balance with known test weight (ca.
1/3 of the max. load) and compare with displayed value.
•The reverification deadline has been exceeded.
8 Tare function (example using a weighing container)
1. The relative weight of the weighing container will be shown on the display.
2. Press the TARE button. The word “Tare”will be displayed.

3. Once stability has been achieved, the zero value “0.0000” will be displayed. In case stability
is not achieved due to drafts, vibrations, or other types of disturbance, the dashes will
continue to be displayed.
4. Place the objects to be weighed in the container. Read the value of the net weight on the
display.
8.1 Manual tare function
This function allows a tare value to be entered manually.
1. Press and hold the TARE button with the weigh pan empty until the beeping stops, and then
release the button.
2. “Manual tare” will be shown on the display:
3. Now insert the desired tare value using the CAL and MENU buttons to increase and
decrease the number, while pressing the TARE button to pass to the next number. During
the entering phase, holding down the TARE button allows you to delete the inserted value.
