SAFETY
To avoid damage to the device or personal injury, please read all operating
instructions carefully before use.
I Don’t use the scale under dangerous working conditions.
I Verify that the required input voltage on the power adapter matches your
locally supplied AC power.
I Turn o and unplug the scale when cleaning or if the scale will not be
used for more than one week.
I Turn o and unplug the scale before connection with other equipment.
I Strong magnetic elds and static electricity can have an adverse eect on
the scale’s accuracy.
I The scale should not be used in hazard areas that have an explosion risk.
SERVICE
− Use only authorized parts and accessories. We are not responsible for any
modications made to the device.
− Breaking the tamper evident seal inside the scale base will void the

INSTALLATION
When selecting a location to use the scale, keep these tips in mind:
I Do not use the scale close to air vents or other sources of drafts such as
doors or windows.
I Do not expose the scale to extreme heat or cold. Keep the scale away
from direct sunlight which may cause it to heat up. Large temperature
uctuations may require recalibration of the scale.
I Avoid dust, dirt, and moisture which may accumulate on the weighing
sensors and cause a malfunction.
3. TEMPERATURE CHANGES
When moving the scale from a high temperature environment to a low
temperature environment (or vice versa), please allow the scale to acclimatize
to its new surroundings for two hours before using. Also, allow sucient
warm-up time after plugging in the scale. For warm-up times, refer to the
specications chart on page 9.
4. SCALE ASSEMBLY
− Place the scale platform sub-assembly
onto the rubber mounting posts and
press down gently to position it.

Preparation
− Turn the scale on: Press (ON/OFF) Key.
Warm up time:
I To ensure proper operation, allow the scale to warm up according to the
warm-up times listed in the chart below:
Model Warm-up Time
HX-Series 60 seconds
INSTANCE
Basic Weighing (after warming up)
Action Description
Press [Zero]
1. Zero the scale.
2. If using a container or tray, place it on the platform.
( example : 20g )
Press [TARE]
3. Press the Tare key to subtract the weight of the container or tray.
4. Place the sample in the container.
( example : 100g )
Calibration / Adjustment
I Note: Calibration and adjustment are performed at the factory. However,
due to dierences in local acceleration of gravity, you should calibrate
your scale at the location of use after receiving it. Calibration should be
performed:
− When you rst receive the scale
− If the scale is moved
− As part of regular scale mainenance

on. The display will show CALu=. The scale is now in calibration
mode.
Choose Unit 3. Press the UNIT key to toggle between weighing units (kg, g, lb, oz).
Press [ZERO]
4. Press ZERO to conrm the weighing unit and proceed to
calibration.
Enter the
Mass
5. Using the UNIT and TARE keys, enter the mass value of the
calibration weight you are going to use:
− Press the UNIT key to toggle between digits
− Press the TARE key to increment the number
I Note: The ideal calibration weight is between 2/3 capacity to full
capacity in order to get the most accurate results.
Press [ZERO]
6. Press ZERO to conrm the mass value. The display will show a
random number (the AD value).
Press [UNIT]
7. Make sure there is nothing on the scale then press UNIT to
conrm.
8. When the display ashes the calibration mass value, place the
required mass on the platform.
Press [UNIT]
9. Once the weight stabilizes, press the UNIT key to conrm the
calibration adjustment. The display will return to the AD value
10. Remove the calibration weight and turn the scale o. Calibration
is complete!
I Note: Calibration should be done using accurate weights. The scale will
accept the weight you enter, even if it is not correct. Take care to enter the
calibration mass value correctly and only use accurate weights.
