2. Install stainless steel platter.
3. Power the scale:
Insert one 9V battery into the battery compartment or apply the
external power adaptor.
Before plugging the power adaptor into the electricity outlet,
check and make sure the input voltage of the power adaptor
matches with the output voltage of the outlet.
If do not match, please do not plug in the adaptor and contact

INITIAL SETUP
How to select internal functions
a. Turn scale off
b. Press and hold TARE, then press ON/ZERO
c. Scale displays Fun-1

Display Segment Check
Under this function, backlight (if equipped) functional
indicators and display segments will be lit up. Contact your
dealer if any display element is missing.

2 auxiliary weight units in addition to metric are available.
These are Avoirdupois and Taiwanese Units.
Under this function, scale displays capacity and division
followed by the selected weight unit on Weight Panel.

9
INITIAL SETUP
Below numeric number 600.1 is the capacity and division of
MII-600 (600g x 0.1g), which is used for illustration.
600.1 g (metric only)
600.1 g lb/oz (metric and Avoirdupois weight unit enable)
6.0.0.1 g lb/oz (metric, Avoirdupois and Taiwanese weight
units all enable)
Select Auto Power Off Function
5 parameters are available: -
0oFF (Auto Power Off Function disable)
4oFF (Auto off when left idle for 4 min)
10oFF (Auto off when left idle for 10 min)
20oFF (Auto off when left idle for 20 min)
30oFF (Auto off when left idle for 30 min)
** Under the Auto Power Off function mode, the scale will turn
off automatically when it is left idle for the selected time.

10
INITIAL SETUP
Select Digital Motion Filtering Function
3 parameters are available:
Filt.0 (filtering function disable)
Filt.1 (filter 1)
Filt.2 (filter 2)
Use digital motion filtering function when the operation
environment is subject to disturbances like vibration, wind flow,
etc. Select higher filter values for worse environments. Filt2
gives the slowest response compared with other 2 parameters.
Select Auto Tare Function
2 parameters are available:
Tr-On (Auto Tare Function enable)
Tr-OFF (Auto Tare Function disable)
Under the Auto Tare Function, the first load applied to scale
will be treated as a container and will be tared off automatically.

INSTRUCTION FOR USE
Before Weighing
Make sure that
1- The scale is placed on a level and strong surface.
2- The stainless steel platter is placed correctly on top of load
receptor.
3- The scale is turned on.
4- The ZERO INDICATOR is on. If not, press ON/ZERO to
set display to zero.
Weighing
1- Always place an object onto the platter gently. Excessive
force applied to platter may cause damages to sensor
inside scale.
2- The weight of the object would be displayed
automatically.
3- It is a good practice to remove all loads from platter after
weighing. It would prolong the lifetime of scale.

12
INSTRUCTION FOR USE
Selecting Weight Unit
Press MODE to shift among various weight units (gram, lb/oz
and Taiwanese) with or without backlight if required. Refer to
page 8 for internal setting procedures.
The weight unit (used before power off) would be employed
when the scale is turned on again.
Set Display Value to Zero when Unloaded
Press ON/ZERO to set weight displayed to zero when unloaded.
Refer to SPECIFICATIONS for maximum zero range.
Tare off the Weight of a Container
When a container is used, follow the below steps to tare off the
weight of it and to obtain a net weight result.
a. Remove all loads away from platter
b. Make sure that zero weight and the ZERO INDICATOR
appear. If not, press ON/ZERO to set it to zero weight.
c. Place the container on the platter.
d. Press TARE.

13
INSTRUCTION FOR USE
After TARE is pressed, NET INDICATOR and then a zero
weight value would be displayed. In this case, the ZERO
INDICATOR will not appear even though a zero weight is
displayed.
Refer to page 11 for weighing procedures. Weight displayed is
the net weight of the subject matter. Refer to SPECIFICATIONS
for maximum tare range.
Clear the Tare Function
a. Remove all loads from platter.
b. The scale will appear a negative value, which is the weight
of the container, and the ZERO INDICATOR appears.
c. Press TARE.
d. After TARE is pressed, a zero weight will be displayed
while the ZERO INDICATOR remains.

14
INSTRUCTION FOR USE
Lo-Bat Indicator
When the LO-BAT INDICATOR appears, it means that the
battery is faded out. Replace all battery with new ones, or apply
the external power adaptor immediately.
Caution
When the power adaptor is being used, remove all batteries
from the battery pack. Failure to do so may cause battery leak/
explosion or damages to the scale.
