EM SERIES
Digital Platform Scale
1． INTRODUCTION
This manual describes how the EM Series Digital Platform Scales work.
Please read this manual completely before using the scale.
1.1. Precautions
CAUTION
The scale is a precision instrument. When installing the scale, consider the
following conditions to get the most out of your scale.
Install the scale where it is not exposed to direct sunlight, where the temperature
and relative humidity is stable and where there is no dust and draft.
Install the scale on a solid and level surface which is free from vibration.
The scale is not waterproof. Do not use it where it will get wet.
Do not disassemble the scale. Do not open the case to repair or modify it. That
may cause a fire or damage to the scale. Damage caused under such conditions
will void the warranty.
If the scale malfunctions, stop using it immediately. Contact the local A&D dealer.
1.2. Features
Three weight display resolutions are available, normal (1/3000), high (1/6000 or
1/7500), and higher (1/12000 or 1/15000).
Two weighing platform sizes are available. The EM-KAM has a smaller pan and
the EM-KAL has a larger pan.
As a power source, either the AC adapter or internal rechargeable battery can be used.
The counting function easily counts the number of objects of the same weight.
The optional EM-03 serial interface can transmit the weight value to a personal
computer or a printer.
1.3. Unpacking
When unpacking, check whether all of the following items are included.

"kg"：Basic weighing mode in kg.
"pcs" (pieces)：Counting mode which determines
a unit weight (the weight of one piece) from the
known pieces of samples and calculates how
many pieces are on the weighing pan using the
unit weight.
Changes as the battery capacity decreases as
shown to the left.
3． INSTALLATION
3.1. Setting up the Scale
Step 1 Pass the cable B through the pole.
Step 2 While taking care not to pinch the cable, secure the pole to the weighing
platform, using two screws.
Step 3 Secure the bracket to the pole, using a nut and screw.
Step 4 Connect cable A to cable B.
Step 5 Bundle the excess cable and insert it into the pole.
Step 6 Attach the display to the bracket.

3.2. Installing the Scale
Adjust the level of the scale, using the leveling feet. Confirm that the bubble of
the spirit level is in the center of the level.
The best installation conditions are: stable temperature (-10 ℃ to 40℃） and
relative humidity ( less than 85% ), solid and level surface, no drafts or vibration,
no direct sunlight.
Do not install the scale where there may be static electricity or sudden changes
in temperature.
4． BASIC WEIGHING OPERATION
Step 1 Press the 【ON/OFF】 key to turn the power ON.
The display shows " - - - - - " if there is something placed on the weighing
pan or the scale is unstable.
Step 2 Press the 【UNITS/MODE】 key to select "kg" ( kg mode ).
Step 3 When the display doesn't show zero, press the 【RE-ZERO】 key.
Step 4 When a tare ( container ) is used, place the container on the weighing pan
and press the 【RE-ZERO】 key to set the display to zero.
Scale weighing range = weighing capacity - tare weight
Step 5 Place the object to be weighed on the weighing pan or in the container. Wait
for the STABLE indicator to turn on and read the value.
Step 6 Remove the objects from the weighing pan.
Step 7 Press the 【ON/OFF】 key to turn the power OFF.
When the auto power-off function is enabled, the scale turns off automatically
after 5 minutes of stable condition and Error displayed.
5． COUNTING MODE
Step 1 Press the 【UNITS/MODE】 key to select "pcs".
Step 2 Press and hold the 【UNITS/MODE】 key to enter
the sample unit weight storing mode.
( The figure on the left is the number of samples. )
Step 3 To change the number of samples, press the
【ON/OFF】 key. It may be set to 5, 10, 20, 50 or 100.
Step 4 If necessary, place a container on the weighing
pan and press the 【RE-ZERO】 key. Confirm that
the right side of the number of samples shows zero.
Step 5 Place the correct number of samples on the
weighing pan or in the container. In this example,
place 20 pieces of samples.
Step 6 Confirm that the STABLE indicator is turned on.
Press the 【UNITS/MODE】 key to calculate and
