2. UNPACKING & INSTALLATION
2-1. Unpacking
Unpack the container carefully. Examine the packaging and the device for any
damage, and report it to the shipper if there is any. Try to keep the scale
upright.
Check for enclosures as follows:
① Scale main ｕｎｉｔ
② Weighing pan with pan base
③ AC Adaptｅr
④ Operation manual
Note : 1. If any items are missing or any damage is discovered immediately notify
your place of purchase or a dealer.
2. Keep box and shock absorber pad after installation. They are required for
transportation.
2-2. Installing the Weighing Pan
Place the pan base packed with the weighing pan on the scale. Fix it by driving
the nut on the pan base to the screw in the center of the scale. Place the
weighing
pan properly on the pan base.
* The receiving element of the pan base is directly linked with the delicate weighing
mechanism. A tension or a side force may damage the unit.
2-3 To Level the Scale
The scale must be level for proper operation. Use the 4 level adjusters located at
the 4 corners of the scale main unit to adjust the horizontal position of the scale
until the bubble of the bubble level lies within the red circle. Ensure that the
scale sits solidly and does not wobble due to uneven adjustme nt.

4-2 Messages by symbolic letters
Symbol Conditions
LIGHT
The UNIT W. is too light for the balance resolution. Impossible to
count, use a balance of smaller capacity.
While flickering, it is possible to count, but a counting error may be
produced due to the rough uniformity of the samples or depending
on the accuracy of the balance.
ADD Please add samples. -- while SCS operation --
NON UNI
The samples are not uniformed or contain some irregular material.
Unload samples until the symbol goes off or pick the irregular
material off from sampling material.
-- while SCS operation --
EXCESS
Too many samples have been added. -- in SCS operation –
Unload samples until the symbol goes off.

3. Press SCS key.
4. Add an optional quantity but within number of acceptable addition
quantity (display on the UNIT W. position).
Adding samples are no needs count.( because acceptable number decrease at
adding.) If too many samples added, sampling cannot be proceeded. Scale tells
you by the sign Sub. Meaning subtract quantity.
Wait to stable after beep then flicker :ADD (on WEIGHT display)
Also change to the acceptable addition quantity.
5. Continue the previous operation until the scale automatically completes
sampling.
However, even before the conditioning, the reference unit weight may be fixed
on by pressing the SCSkey at an optional time when the fixation is required.
(In this case, sampling accuracy is not guaranteed.)
Features
- Operators can just concentrate on counting a few pieces.
- Just following the instruction brings accurate sampling.
- Re-sampling is not necessary in most cases.
- No sampling error. (not depend on operators)
- Scale rejects samples in failure of unit weight set.

When the quantity is under the low value, it is ranked as “ LO “
When the quantity is between the low value and the high, it is ranked as “ OK “
When the quantity is over the high value, it is ranked as “ HI “
Notes
# Such settings as lower limit value >= Higher limit value will be error.
# Comparative judgment condition;
At one point(13.Pn.1) :
LO : value < lower limit. OK: lower limit =< value.
At two point(13.Pn.2) :
LO: value < lower limit
OK: lower limit =< value =< higher limit
HI : higher limit< value
# We get beep sound in response to comparing result.
The condition is selectable by function set.

6. CALIBRATION
We recommend you to calibrate the balance with a reference weight of full
capacity of the scale according to the following procedure, just before the
operation whe n it is installed, transported, or after certain time passed from the
previous calibration.
Particularly it is necessary when the working district of the scale is changed,
since the measuring data changes proportionally to the change of G of gravity
which changes according to the latitude.
The following calibration procedure is simple, and not subject to operator errors,
but does require a reference weight of the full capacity of the scale.
(１) Press the MODE key and keep until Func appears for roughly 5 to 6 sec., and still
continue pressing until CAL appears.
(２) Press the T key, with it still held down, just hit the MODE key, and release both keys
together.
(３) The display will indicate unitX . Select weight unit from parameters “0” to “2”,
by pressing the T key. The contents of the parameters are the same as at function
A.un.X. See page17. After setting the parameter, press the MODE key.
(４) The display will indicate on0. Verify that no load is placed on the scale, as the
zero adjustment is automatically achieved.
(５) Allow to appear onFS. Apply the reference weight of the full capacity of the
scale just in the center of the weighing pan. The span adjustment will
automatically be achieved. Use a weight of the unit selected in above (3).
(６) When the calibration is completed, the display will automatically return to the
measurement mode.
19
NOTES
１.To stop the calibration operation, press any key (Ex. RE, C/AC, T key) without
pressing the MODE key to return to the working area.
２.O‑Err signs that the reference weight is over the full capacity.
３.The calibration is available with a reference weight of over 50％ of the scale
capacity. Nevertheless, we recommend to adjusting by a full capacity weight.
1‑Err will appear if the load is less than 50％ of the capacity.
４.2‑Errwill appear if the error exceeds 1％ of the capacity, or any other object than
a reference weight. Or, perhaps the scale is defective.
BATTERY OPTION （Nicd battery pack）
Charge hours : Approx. 12 hours ( at 120VAC use) to 15 hours (at 230VAC use)
under power switch of the scale “OFF”.
Operation hours : Approx. 5 hours continuous operation without output.
Auto-Sleep : Sleeps 3 minutes after last operation, for power saving.
Low Battery : LOW-BATT symbol appears on when the voltage falls under
the specification.
