2 Introduction to KERN EC Counting Balances
Your KERN EC counting balance is the most convenient instrument for piece
counting. Preparation before counting objects is simply loading 10 or 30 pieces
sample on the balance and pressing "10" key or "30" key.
Your KERN EC does not require adjusting in long term operation. Adjusting is
required only when it is relocated, not before daily operation.
3 Unpacking and Accessories
Carefully unpack the balance and keep the packaging for possible future use when
transporting the balance.
You should find included in the package:
• Balance
• Weighing platform
• Support for the weighing platform
• Mains adapter
• Operating instructions
4 Setting Up
Place the pan base packed with the weighing pan on the balance. Fix it on the shaft
by driving the knurled nut in the centre. Place the weighing pan properly on the pan
base.
20 EC-BA-defs-0113
5 Levelling
Watch if the balance is level. Locate the level in front of the balance and four
adjusting legs beneath it. Drive these legs to centre the bubble in the red circle of the
level. Watch if all legs are settled on the table securely. See (b).
6 Electrical Supply
The mains Adapter should only be connected to a 230 V / 50 Hz electrical supply. Do
not connect to any other mains voltages unless another mains voltage is specifically
given on the Model label.
The plug must be grounded according to VDE regulations.
Attach the adapter cable to the rear of the balance.
Only then:
Plug the mains adapter (230 V AC / 9 V DC / 400 mA) in the socket.
Adjust the balance, see chapter 11 "Span Adjusting".

Key Functions
ON
OFF
: ON/OFF key for power.
MODE : Key for changing display, pcs, weight or unit weight. Also for
calling function, for storing parameters, for setting digits of
parameters.
10 : Key for sampling unit weight with 10 samples.
30 : Key for sampling unit weight with 30 samples.
TARE : Key for tare. Also for election of parameters.
EC-BA-defs-0113 23
Characters
g, kg, lb : Weight unit in weighing.
P : Indication of pieces in counting mode.
: Total sample weight on the pan is too light to process an
accurate unit weight.
: Indicates battery has run out (option).
M : Indicates the balance is under setting operation, or sampling.
Upper : Appears when other weight unit than "g" or "lb" is selected.
It is recommended to stick a seal of the weight unit at the mark.
Lower : Indicates the balance mode is in Unit Weight Display Mode.
9 Installation
Location
KERN EC balances are very robust, still it is an "precision weighing instrument"
which requires gentle operation and handling with care. Install the unit in good
conditions for optimum results. Locations as follows may cause erroneous results.
1. Areas having a soft floor to make the balance
not level.
2. Areas where temperature changes abruptly.
3. Areas in high humidity or dusts.
4. On an unstable base or near to a source of
vibration.
5. Areas exposed to a wind from a fan or a
cooler.
6. Areas exposed to direct sunlight.
24 EC-BA-defs-0113
10 Counting Operation
1. Tare the balance by pressing the T key.
Display: Exactly 0 p.
If otherwise displayed, press MODE key
once or twice to read exactly 0 p.
2. Place samples pre-counted, 10 pieces or
30 pieces on the pan.
Press 10 key or 30 key corresponding to
the sample quantity.
3. The display turns blank while lighting small
M mark on the left.
Then a "piece" display, 10 p or 30 p
appears while the M mark disappears. Now
the unit weight is processed and
memorised.
4. Load the rest of objects to be counted and read the display which indicates the
total number of the object on the pan.

11 Functions
How to access and change various functions
Access to Functions
(1) Press Mode and release it when "Func" appears
showing that the balance is in function mode.
Auto Zero
(2) The first mode of the balance "1. A.0_" for Auto
Zero appears.
To change the parameter at the last digit, hit T key.
As to contents of parameters, see next page.
(3) By hitting Mode, the function item will advance
successively according to following sequence.
Auto Power Off Zero Setting

↓(Interfacing
Response Interface Conditions) Weighing Unit
→→→
"41.oc._" will be passed depending on setting.
Points of key operation
* To advance the function item, hit Mode key.
** To change parameters, hit T key.
