!!!! NOTICE !!!!
The CZ 1200 High Precision scale is a very sensitive and
delicate electronic instrument.
For accuracy of weighments, certain factors regarding
location of use must be taken into consideration, i.e.,
- Place on very stable surface
- Away from air movement
- Away from vibrations
- Away from electronic noise
- Away from magnetic fields.

Set Up
PRECAUTIONS AND REQUIREMENTS
FOR PRECISION WEIGHING
Precision scales should be placed in a location that
will not degrade the accuracy.
Avoid extremes of temperature. Do not place in
direct sunlight or near air conditioning vents.
Avoid unsuitable tables. The tables or floor must be
rigid and not vibrate. Do not place near vibrating
machinery.
Avoid unstable power sources. Do not use near
large users of electricity such as welding equipment
or large motors.
Avoid high humidity that might cause condensation.
Avoid direct contact with water. Do not spray or
immerse the scales in water.
Avoid air movement such as from fans or opening
doors. Do not place near open windows. Keep the
scales clean.
Do not stack material on the scales when they are
not in use.
THE CZ PRECISION SCALE
Level the scale by adjusting the four feet. The scale
should be adjusted such that the bubble is centered
and the scale does not rock from corner to corner.
Attach the adapter to connector on the side of the
scale, plug into standard 110VAC outlet.

Key Functions
ZERO/ENTER
ZERO: Sets zero point for all subsequent weighing.
ENTER: For setting parameters or entering other
functions.
TARE
Tares the scale. Stores the container weight in
memory as a tare value, subtracts the tare value
from the total/gross weight and shows the resulting
net weight.
PRINT/ESC
PRINT: To print the results to a PC or printer using
the optional RS-232 interface.
ESC: Return to normal operation when the scale is
in a parameter setting mode, avoids saving recently
entered changes.
UNIT/MODE
UNIT: Selects either grams, pounds, carat ,ounce
etc. for the weighing unit when weighing mode.
MODE: Press during start up self-checking to
access parameter setting mode. When in settings
mode, press to proceed through parameters.
S
Press the S key during self-checking to display
the number audit operations.
P
Press the P key during self-checking to display
the number of calibrations performed. When the
counter becomes full, it will start over at 0.
ON/OFF
Power on, power off.

Operation
ZEROING THE INDICATED WEIGHT
Press the ZERO key at any time to set the zero
point from which all other weighing and counting is
measured, within 10% of power up zero. This will
usually only be necessary when the platform is
empty. When the zero point is obtained the display
will show the icon indicating center of zero.
The scale has an automatic re-zeroing function to
account for minor drifting or accumulation of
material on the platform. When the weight goes
over 20 % of the full capacity, automatic zeroing
is disabled.
TARING
If necessary, zero the scale by pressing the
ZERO key. Place the container only, no contents,
on the scale platform.
Press the TARE key to tare the scale. The weight
that of the container is stored as the tare value
and that value is subtracted from the display,
leaving zero on the display.
The “NET" indicator will be on. As product is
added only the weight of the product will be
shown. When the container is removed a
negative value will be shown.

WEIGHING AN ITEM IN A CONTAINER
To determine the weight of an item(s) in a
container, first tare the empty container then place
the item(s) in the container. The display will show
the net weight.
TO ACCUMULATE WEIGHTS
1) Place first item on the scale platform.
2) After the stable icon displays ( ), press the
PRINT key.
3) “ACC 1” will display.
4) Remove all weight from scale platform, then
place next item to be weighed on the platform.
5) Per #2 above, press the PRINT key
6) “ACC 2” will display, followed by the accumulated
total.
7) Repeat the procedure as required to accumulate
all weights.
TO RECALL ACCUMULATED WEIGHT: With
nothing on the platform, press the PRINT key.
TO DELETE ALL ACCUMULATED WEIGHT IN
MEMORY: Power off, power on the scale.

VIEW AUDIT & CALIBRATION COUNTS
Calibration Counter
Press P key during self-checking, display will show
number of times scale has been calibrated. When
the counter becomes full, it will start over
at 0.
Audit Operation Counter
Press S key during self-checking, display will show
number of audit operations.
Adjusting the Parameters
To access the parameter settings, press the MODE
key during the start up self-checking.
F1 Unt will display. Press the MODE key to move
through the available parameters.
To access the settings in the parameter showing in
the display (such as F1 Unt), press the ENTER key.
The first setting will display (such as “on ct” in the
F1 Unt parameter).
To navigate through the available options for the
setting, press the MODE key (such as “on ct” or oFF
ct”).
To accept the option being displayed, press the
ENTER key. If more than one setting is available in
the parameter, the next setting will display.
To save the settings, press the Enter key as needed
to return to the parameter title (such as F1 Unt),
then press the ESC key.
