2 Safety instructions
2.1 General safety information
Follow these safety precautions:
-The equipment may only be used as intended for weighing tasks.
-Observe the operating limits of the device.
-Avoid shock stress (falling down, hard shocks, falling loads, any impact from the side).
-Do not use the equipment in hazardous areas and unstable environments.
-Do not expose the equipment to aggressive chemical vapors or to unnecessarily
extreme temperatures, moisture, or vibration.
-Unplug the device before you connect or disconnect any electronic peripheral devices
to or from the interface port.
-Unplug the power cord from the mains supply before cleaning.
-Make sure that no liquid enters the equipment.
-Unplug the power cord from the mains supply befory servicing or making internal
connections. The housing may only be opened by authorized and qualied personnel.
-Do not use loads that exceed the capacity of the scale.
2.2 Incoming goods inspection
The shipment must be checked for completeness. A visual inspection must be performed
to determine if the shipment has been damaged. If there are grounds for a complaint, this
must be brought to the attention of the delivery company immediately. A Minebea Intec

-Safety Instructions and QR code with access to the detailed documentation
3.2 Requirements on location
-Set up the device on a stable, even surface.
-Position the device so that the power plug is freely accessible and the power cord is
not an obstacle or trip hazard.
-Avoid placing the device in close proximity to a heater or otherwise exposing the
scale to heat or direct sunlight.
-Do not expose the device to excessive temperature utuations.
-Protect the device from drafts that come from open windows or doors.
-Avoid exposing the device to extreme vibrations during weighing.
-Protect the device from aggressive chemical vapors.
-Do not expose the device to extreme moisture over long periods.
3.3 Power supply
AC power is used to power the scale when battery power is not needed.
Plug the USB-C plug into the USB-C jack on the bottom of the unit, then plug the AC
power supply into a wall outlet.
Note:
Do not use the USB-C power supply cable for the PC communication. Instead use a
standard USB-C cable.
3.3.1 Battery Power
The scale can be used on AC power immediately. Allow the battery to charge for 12 hours
before using the scale on battery power. The Scale will automatically switch to battery
operation if there is a power failure or the power cord is removed. With AC power, the
scale is constantly charging, so the battery charge indicator (see Chapter 4.1.1.2) will
remain lit. The scale can be operated during charging, and the battery is protected
against overcharging.
When the device is switched on, the battery status LED lights red while the battery is
charging and green when the battery is fully charged.
For maximum operating time, the battery should be charged at room temperature.
During battery operation, the battery symbol indicates the battery charge level
remaining. The indicator will automatically turn o when the batteries are empty.

5.2.2 Counting Mode
Counting items based on the weight of a reference sample count.
Example: Determine the number of parts; weigh in the selectable reference sample
quantity (in this example: 20).
Release the button. The application is activated.
The stored reference quantity from the initialization before is displayed. The number
of selectable samples is blinking.
1. To select application Count, press the

F
button, until [COUNT] is displayed with
application icon at bottom of the screen.
2. If there is already a piece weight initialized, [CLR.PW] is displayed. Otherwise [PUT
20] (for example) is displayed, then go on at step 4.
3. Press the
Unit
(No) button to use the stored reference weight.
4. Press the

If there are no reference samples put on the pan or the weight is smaller than 2d or
the calculated piece weight would be smaller than 2d/10, the display will show
[REF.ERR] for about 2 seconds and then goes back to step 9.
If the weight on the pan is < reference quantity * d AND also calculated piece weight ≥
(2d/10), then the display will show[LOW.REF] for about 2 seconds.
Example: PUT 50 ; d = 0.2 g ; weight on the pan = 2.0 g ; then [LOW.REF] is displayed.
But is the weight on the pan = 1.8 g, then [REF.ERR] is displayed.
9. Press the
Off
(Yes) button to store the reference quantity sample.
The display shows [PW.OK] (piece weight ok) for 2 seconds. Go on step 10.
10. Counting is initialized. On the display, the actual number of pieces is shown: [20

5.2.3 Check Mode
Counting items based on the weight of a reference sample.
The scale supports positive, negative and zero check weighing.
Positive Check To determine when the material added to the scale is within the target
range.
In this case the limit values UNDER and OVER must both be positive
values.
The OVER limit must be greater than the UNDER limit.
Add material to the scale until it is within the ACCEPT (green) range.
Negative Check To determine when the material removed from the scale is within the
target range.
In this case the limit values UNDER and OVER limits are negative
values.
(The UNDER limit must be greater than the OVER limit, i.e. UNDER
= -10 / OVER = -15).
Place the item to be weighed on the scale and press
T
.
Remove a portion of the item until it is within the ACCEPT range.
Zero Check For comparison of subsequent samples with an initial reference samp-
le.
In this case, the UNDER limit must be negative value and the OVER li-
mit must be positive value or zero.
Place the reference item on the scale and press
T
.
Remove the reference sample and place the item to be compared on
the scale to determine if it is within the ACCEPT range.
Checking for exact one piece weight value is also possible. Enter for the low AND high li-
mit the same value.
The dierent check modes must be activated prior via menu (see Chapter 6.2.1).
5.2.3.1 Check Weighing Mode
Compare the weight of items to a targeted weight range.
Example: The required target weighing range is between 1 kg (low limit) to 1.1 kg (high
limit)
The scale will display [REF.WT] and the reference piece weight value.
