• When the rechargeable battery is fully charged the scales can be used for 20 hours
continuously.
• When the power supply registers <5.4V(±0.1V), the scales will be turned off
automatically.
• When the power supply registers <5.7V(±0.1V) but over 5.4V(±0.1V), the scales will
alternatively display
Lo.bAT
and whatever the screen currently displays in its normal
mode.
• If the AC adaptor is used to charge the battery or to power the scales, the switch on
the underside of the scales must be switched to the
on
position.

6. Recharging current:
<400mA.
1. ZERO/ON/OFF
(i) Press this button to activate the scales. The scales perform its self-examination mode,
display the working voltage
x.x Udc
, display the machine’s capacity (F6.000kg or
F15.000kg), before finally setting the zero point and displaying a zero reading.
Note: The power-on zero-point range is: calibration zero-point ±20% FS (full scale weight
capability).
(ii) To reset the scales to zero after any operation, press the
ZERO
key for less than five
seconds. Pressing the
ZERO
key for more than five seconds will activate the
ON/OFF
function.
The ZERO key range is power-on zero-point ±5% FS. The
ZERO
function is used to clear
any
TARE
weight that may be displayed after previous weighing operations. When the
TARE
weight is displayed the
NET LED
will be activated. After using the
ZERO
function
the
ZERO LED
will be shown. If the current weight exceeds ±5% then the
ZERO
operation is disabled and the display will read
0
______
or
0______
, before returning to
the previous reading.
2. TARE/UNIT
Pressing the
TARE/UNIT
key for less than five seconds activates the
TARE
function.
Pressing the
TARE/UNIT
key for more than five seconds activates the
UNIT
function.
The
TARE
range for these scales is up to 102%FS. The
TARE
function should be
activated when the scales are in normal mode, i.e. the display reads 0 and no items are
on the weighing tray.
When the
TARE
weight is not reading 0, the NET LED light will be activated.
Note: Gross weight = Net Tare weight
£
102%FS.
UNIT:
The
UNIT
function is used to select the weight scale (lb, kg, g, oz, lb.oz).

Warnings
Cleaning the scales
The calibration of this product requires specialist tools and should only be carried out by
persons with appropriate skills/qualifications. Should you experience any problems please
return the goods to your supplier, who will arrange professional calibration of the scales.
UNDER NO CIRCUMSTANCES SHOULD MAINTENANCE OR CALIBRATION BE ATTEMPTED
BY PERSONS WITHOUT APPROPRIATE SKILLS OR QUALIFICATIONS. SUCH ACTIONS MAY
RESULT IN IRREPAIRABLE DAMAGE AND WILL ALSO INVALIDATE ANY GUARANTEE OR
WARRANTY.
The scales incorporate an
AUTO-OFF
function. To activate this action the scales must be
switched on. To set the function, press the
TARE
and
ZERO
buttons for more than 5
seconds until the
A.oFF.x
message is displayed.
Setting the
AUTO-OFF
function time is achieved by pressing the
TARE
button the required
number of times, until the desired
AUTO-OFF
time is displayed (i.e.
A.oFF.4
will cause the
scales to switch themselves off after four minutes).
The
AUTO-OFF
time is confirmed and saved by pressing the
ZERO
button.
If the scales are to be used in wet or damp conditions using a mains electrical connection
(110V/230V), the supply must be correctly fused and protected by an approved RCD which
conforms to BS7071 or BS7288 or IEC1008-2-2 BS EN 61008:1995.
IF YOU ARE NOT
SURE ABOUT THIS WARNING YOU MUST SEEK THE ADVICE OF A QUALIFIED
ELECTRICIAN.
To avoid an electric shock, or permanent damage to the machine, you must isolate the
scales from the electricity supply before carrying out any routine maintenance.
To avoid damage to the display, top plate or body of the scales, it is not advised to use any
harsh abrasives, scouring cleaners and alkaline solutions, such as washing soda, when
cleaning the scales. Special care should be taken when cleaning the digital display screen,
which could be permanently damaged by the use of inappropriate cleaning agents.
DO NOT
ATTEMPT TO CLEAN ANY INTERNAL COMPONENTS.
Best cleaning results are obtained by the use of a clean, lint-free cloth, which has been
slightly dampened using a weak water and washing-up liquid solution.
