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.

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".
