compartment cover by
pressing the tab to the
rear and tip it off. FIG 1
2. Install the four AA
Alkaline Batteries into
the compartment and
replace the cover. FIG 2
A. Battery Insertion:
CAUTION: WHEN INSERTING THE BATTERIES, KEEP THE
COVER CLOSED TO PREVENT PRESSURE TO THE LOAD CELL
PLATE ON THE TOP SIDE OF THE SCALE. THE SCALE IS NOT
DESIGNED FOR WEIGHT EXCEEDING 100 GRAMS.
CED PRO II SCALE INSTRUCTIONS
Congratulations on your selection of the CED PRO II high precision electronic scale.
The CED PRO II is a highly sensitive Electronic Computerized Load Cell Scale. With
many features only found in very expensive laboratory and jeweler's scales, the CED
PRO II is balanced and designed for multi-purpose usage. The maximum capacity is 100
GRAMS or 1500 GRAINS and the resolution is 0.01 GRAMS or 0.1 GRAINS. Features
include: an Anti-Static draft shield, Calibration function, Tare function, an Overload cell
protector, Automatic shutoff, and universal AC or battery operation for portability and eld
use.
No other scale on the market today provides as many quality features and value as the
CED PRO II
B. AC Adapter / Battery Eliminator:
(NOTE: Use of an AC adapter other than the
one provided may damage the scale.)
1. Your scale can also be operated on 110-240V universal
AC by using the furnished AC adapter. This adapter
provides DC and plugs into the jack at the center rear of
the scale.
2. Insert the adapter plug into the socket on the rear of the
scale and then plug the adapter into
an AC outlet. DO NOT SUBSTI-
TUTE AC ADAPTERS. Only use
the AC adapter provided with the
scale. FIG 3

C. About The Scale:
1. Select a FLAT and LEVEL surface,
which is not subject to vibration or air
movement.
2. Turn the scale on by pressing the ON/
OFF key once. FIG 4
The scale is now on. The display will
show "+88.8.8.8." and then "0.00"
with a small letter "g" for "g:gram"
on the upper right side of the display.
This indicates that the scale is ready to
use. The "MODE" key will allow you
to toggle between GRAMS, GRAINS,
CARATS, PENNYWEIGHT,
OUNCE, and TROY OUNCE, after
turning the scale on, even if there is
something being weighed at the time.
3. The CED PRO II Scale will weigh in
the following modes and capacities:
CAPACITY (by weighing unit)
- Grams: 100 g
- Grains: 1543 gn
- Carats: 500 ct
- Pennyweight: 64.3 dwt
- Ounces: 3.52 oz
- Troy Ounce: 3.2 ozt
4. When this scale is used in any location
where air movement may be a factor,
the "draft shield" should be put
down (closed) covering the weighing
platform, to prevent inaccurate
readings due to environmental
inuences. This specially designed
cover incorporates an anti-static
material to eliminate uctuations in
readings. This prevents inaccurate
readings due to static electrical build
up. (A feature normally found only
on very expensive laboratory scales).
When used in indoor environments
without inuences, the cover should
be lifted up to allow easy access and
use. FIG 5
5. This scale features an automatic shutoff
after approximately 5 minutes of
inactivity (battery power only) at
which time it will shut itself off.
This conserves battery drain,
and protects the scale
from being left on for
prolonged periods
of time when not
in use.

D. Calibration:
1. FIG 6 This scale was calibrated before
shipment from the factory, but must be
re-calibrated before use and it must be
re-calibrated after every repositioning of
the scale and before each additional use
if stored for any period of time.
2. Calibration can be affected by the fol-
lowing factors -
1. Handling during shipment.
2. Changes in work locations,.
3. Drastic changes in temperature.
E. Calibration Procedure:
1. Make sure the 100 GRAM calibration
weight is available before proceeding.
2. If the display is not showing "0.00"
grams, then press the "ZERO" key once
before proceeding. The powder pan
should not be on the platform. Wait for
the display to show "0.00" grams.
3. Press and hold the "CAL" key for 4
seconds until the display indicates
"100.00 grams" by blinking on and off.
FIG 7 Press the "ON/OFF" key once and
the display will show "CAL O" which
indicates that the zero point is set. FIG 8
4. GENTLY place the 100 GRAM cali-
bration weight on the platform and wait
until "CAL F" is displayed. FIG 9 The
scale is now calibrated and ready to use.
Remove the weight and wait for 0.00 to
appear. If 0.00 does not appear, press
ZERO to return the scale to zero. If
you wish to check the calibration, place
the weight on the platform and 100.00
± 1/100th gram will appear. The scale
may not read exactly 100 grams due to
variations in the manufacturing of the
100 Gram weight. The key is that the
scale should give you the same reading
in repeated weighing of the same object
within the given tolerance range. (99.99
to 100.01)
5. If the display shows "CAL E" FIG 10, it
means an error has occurred during the
calibration procedure. Retry until 0.00
appears.

G. Operation of the Scale (weighing powder):
1. Turn the scale on by pressing the "ON" key and wait until the display reads "0.00"
grams. If the scale is not in the mode desired, then press the MODE key to change the
weight unit accordingly. The selected weight capacity (grams or grains for example)
will remain even when the scale is turned off and then on again. Once the proper weight
capacity is selected, the scale is ready to weigh powder.
2 Place an empty powder pan on the scale. FIG 12
3. If there are environmental variables affecting the scale's performance, then lower the
Draft Shield to stabilize the readings.
4. Press the ZERO key to
"zero out" the scale. This
will remove the powder
pan weight allowing only
the powder itself to be
weighed. This function is
called "TARE Function"
FIG 11
5. Wait till the scale reads
"0.00". At this point the
scale can be used to weigh
any object that will t on
the platform (within the
weight range of the scale).
6. Pour powder into the
powder pan. Allow 3-4
seconds for the display
to settle (because of the
scale's extreme sensitivity,
the display may uctuate
slightly, if so, check for
vibration or air move-
ment). Read the weight of
the scale.
7. Turn the scale off when
you are nished.
FIG 12
F. Re- Zero Function:
Press the "ZERO" key at any time to
re-zero the scale. This is a good idea if it
is moved during a weighing process. FIG 11

H. Trickling Powder
1. The CED PRO II Scale is designed to allow “trickling” of powder. This can be used
to “ne tune” a powder charge (load) in use. It is best to use a Powder Trickler for this
function, but trickling by hand can be done if performed properly.
2. FIG 13 Place a xed amount of powder on the powder pan. Wait till the reading stabilizes.
Then slowly add powder from the Trickler or by hand to increase the amount of powder
in the pan until the desired amount of powder is reached.
3. CAUTION: Trickling on ANY electronic scale takes a certain amount of learning
curve. Digital scales have “lock in” mechanisms designed to stabilize the readings
and prevent constant uctuations. If the trickling function is performed TOO
SLOWLY, it is possible to “fool” the scale. In this case, the scale will remain locked
on the reading displayed even though more powder is actually being added. When
this occurs, it is possible to have a powder charge indicate a lighter weight than is
actuality there. To prevent this, it is necessary to trickle at a rate that allows the
scale to determine increased weight being added to the scale. It is always recom-
mended that the nal weight be “checked” periodically to make sure it is accurate,
especially until the user is comfortable in the trickling function.
FIG 13
CED Professional Digital Scale manual.indd 6 14/10/2016 16:40

CAUTION:
1. Place objects onto the weighing platform VERY GENTLY.
2. Do not weigh any object which will exceed the capacity of the scale. This could perma-
nently damage the load cell sensor. (The scale's capacity of 1500 grains is equal to about
3.5 ounces.) The powder pan weighs about 175 grains and this must be considered.
3. Turn off the scale when not in use by pressing the "ON/OFF" key. This will prevent
unnecessary battery drain. Also unplug both ends of the AC adapter when the scale is
not in use.
4. Always keep the calibration weight clean. The effects of accumulated body oils and dirt
can cause the calibration operation to be off by 1/10 of a grain or more.
5. Always keep the unit away from heat and direct sunlight.
6. The scale should be kept clean and away from moisture. Only clean with a clean dry
cloth.
