3. INSTRUCTIONS FOR USE
3.1 POWER FOR THE SCALE
The HS hanging scale can be powered either by 4 x C
batteries (not supplied) or a power adaptor with output
of 9V DC 100mA (optional accessories).
3.2 POSITIONING THE SCALE
The scale must be suspended from a suitable structure,
e.g. a wire rope, from a firm support that will withstand
at least 5 times of the scale rated capacity for maximum
operating safety.
3.3 PLACING CONTAINER OR PAN SUPPORT (OPTIONAL
ACCESSORIES)
Before turning the scale on, place the container or pan
support on the hook first.
3.4 APPLYING A LOAD
Always place the load on the scale gently, sudden shock
or excessive force may cause damage to the weight sensor
inside.
It is a good practice to remove all loads from the hook
immediately after weighing. This will help to prolong
the lifespan of the weight sensor.
3.5 HOW TO SWITCH BETWEEN METRIC AND LB WEIGHT UNIT AND
BACKLIGHT STATUS
Turn scale on, press MODE to switch between metric (kg
or g) and avoirdupois (lb, lb/oz) unit, with or without
backlight (optional accessories).
When backlight function is employed, backlight will
automatically go off 2 seconds after zero weight is
detected and will automatically return when a load is
applied again.
NOTE: To comply with the law of certain countries, the
avoirdupois weight units may be disabled.
3.6 HOLDING THE WEIGHT DISPLAYED
To hold the weight displayed, press HOLD after displayed
weight is stable. To disable the holding function, press
HOLD again.
