Contact your dealer if any item is missing.

2. Install stainless steel platter.

3. Power up the scale:
Insert one 9V battery (not supplied) into the battery
compartment or apply the external power adaptor. The
power adaptor jack is inside the battery compartment.
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

INITIAL SETUP

The example below 600.1 is the capacity and division of
ZS-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 disabled)
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 operating
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

INSTRUCTION FOR USE

Before Weighing

Make sure that
1- The scale is placed on a level and stable 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

damage to the sensor inside the scale.
2- The weight of the object will be displayed

automatically.
3- It is a good practice to remove all loads from platter

after weighing. It will prolong the life of the 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. (For
backlight, just keep pressing the mode until the display is
backlit)
The weight unit used before power off will 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 steps below 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, the NET INDICATOR and then a
zero weight value are 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 display 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 power is low. Replace the battery with a new
one, or apply the external power adaptor immediately. The
power adaptor jack is inside the battery compartment.
