2. APPLICATION
Electronic scale CY - CG is appropriate for precise measurements mass in
laboratory conditions with possibility of setting to zero in all measure range. Balance
calibration is done by CAL on balance keyboard.
Functions accessible to user are divided into 4 parts:
!Functions for weighing units (press F key)
-Weighing in grams,
-Result with 3 places after dot,
-Weighing in carats [ct],
-Weighing in units from beyond SI: [GN], [mom], [oz], [dwt]. Access to
these units is blocked from factory menu level.
!Functions for calibration and weighing modes
(tare key + f key)
-Summing function
-Counting pieces
-Control of deviations % according to standard mass
-Thickness of liquids
-Thickness of solids
!Choice of criteria of stable result depending on conditions of using
(tare key + cal key)
-Turn off/on system of autozero
-Summing function
-Turn off / on automatic calibration in relation to changes of temperature
-Turn off/ on automatic calibration in relation to time from last calibration
-Setting amount of average measurements
-Average result of weighing
-Adjusting balance for dosage procedure
-Select default unit of weighing
!Function for using RS 232
(tare key + print key)
-Choose speed of transmission
-Define sent data as: stable / not stable
-Continuous work
-Setting data as additional element of parameter in printouts
-turn on/off marking of last digit in printout
Moreover balance can be used to weigh hang loads, print report of
calibration, check deviation of calibration and print reports of testing
thickness of liquids and solids.

3. CONDITIONS OF APPROPIATE USING
•scales should be used and stored in rooms without vibrations and shakes,
without drafts and dust
•temperature of air should be +15
o
C ÷+35
o
C
•during using balances changes of temperature shouldn’t be higher than
0,5oC per one hour
•scales should be replaced on wall console or stable table, far from sources
of heating
•strong magnes is installed inside of balance – so it’s important to be carefull
during weighing magnetic materials. Use hang loads if it’s possible not to
expose magnetic load to magnes influence. Suspension is replaced on basic
of the balance.
•If static electrisity has influence on scale annunciators it’s neccesary to
connect it to earth. Earth screw is replaced in back part of balance base.
•Scale should be replaced in horizontal level to assure precision of weighing

4. KEYBOARD
Key ON/OFF is to turn display off. Others subassemblies are still
suppplying and scale is in stage of waiting for further work. If user
press this once again weighing stage with measure units are
displayed.
PRINT key is to send current state of display to external mechanism
by connector RS 232
CAL key is to calibrate. It’s manual calibration. After press if scale
starts calibration. There shouldn’t be any load on scale. If you press
TARE during calibration calibration stops and weighing returns
Fis function key. It’s to choose measure unit (in which measurement
is done) or to change some functions in user menu
TARE key is to sett indication to zero. After setting to zero indication
is zero. If load is taken off scale display show its mass with “minus”
sign. Setting to zero can be done in all measure range of scale

5. START AND SERVICE
Before supply is turn on glass of weighing chamber should be draw
Balance should be leveled. To level scale screw legs in order air bubble was in
centre position.
TIME OF HEATING
It’s neccesary to wait untill scale gets heat stabilization. It’s time of own heating.
User has to wait 15 min. in case of analitycal scales.
Given values refers to scales that were in temperature of conditions of work
before they are connected to suppling net.
If scales were in much lower temperature (f.eg. in winter) time of acclimatization
and heating is 4 hours before connect to supply net. During warm stabilization of
scale indications on display can change.
After time of warm stabilization press TARE key – zero indication of mass appears
on display and orders Stab and Zero. Balance is ready to weighing. If display
doesn’t show zero stage press TARE once again.

6. WEIGHING
Before weighing or if the conditions of work changes (f.eg. if temperature of
surrounding is higher then 3
o
C) scale should be calibrated according to way
in point 7.
• Scale should be load few times by mass close to max capacity befor
measurements
• Check if not load scale shows „precise zero” - ZERO if measurement is
stable - order STAB,
if not press key TARE,
• by means of F key sett measure unit
•g, ct, and if they are accessible in factory menu GN, mom, oz,
dwt,
• put load on scale and read result on display
• indication can be setting to zero many times by pressing key TARE
(summary of mass loads recordede to scale memory cannot be bigger then
its max capacity)
Don’t turn off scale from supply power between following
measurements. Turn scale off by key ON / OFF.
If user press key ON/OFF once again scale is ready to
following measurements.

- 9 -
7. CALIBRATION
To assure very precise weighing introduce correction factor to balance memory –
it’s calibration. Scales have system of internal calibration (calibration mass with all
automatic system is built inside of scale)
Balances CG and CY can have:
-system of internal calibration ( calibration mass with automatic system is
installed inside of balance) - option
-System of external calibration (calibration is done by external weight)
Calibration should be made if:
•we start weighing
•there are long breaks between following measurements
•temperature of surrounding changes not more than 3
0
C
During calibration platform of balance cannot be loaded.
If there is load on platform order unLoad appears on display. This is
command to take load off platform.
Calibration can be stopped if it’s neccesary.
To stop calibration press key TARE after
pressing key CAL.

- 10 -
7.1. Balance with external calibration
Pressing key CAL causes calibration of balance
- on display appears:
(balance starts autotest for calibration –during test you cannot load the scale), and
then order
(it is command to put calibration mass on scale) calibration mass is given in grams.
If you the mass on scale on display appears
calibration and then
take calibration mass off scale. After take calibration weight off scale balance shows
zero. If unsuitable load is put on scale – balance displays
CAL ER (calibration is cancelled)
