7.0 BATTERY OPERATION
• The scale has an internal rechargeable lead acid battery. This
enables the scale operate for 50 hours when fully charged or less
if the backlight is on.
• When the battery needs charging the low battery symbol will be
on and the display will show “LO bAt” for a few seconds before
turning off. The battery should be charged immediately.
• To charge the battery, simply connect the power supply module to
the bottom of the scale. The low battery symbol will flash during
the time the battery is being charged. The scale need not be
turned on, however the symbol will not be on if the scale is off.
• The battery should be charged for 12 hours for full capacity.
• Above the display is a LED to indicate the status of battery
charging. When the scale is plugged into the mains power the
internal battery will be charged. If the LED is green the battery is
being charged. If it is red it is nearly discharged and yellow
indicates the battery is increasing the charge level. Continue to
charge overnight for a complete re-charge.
8.0 BACKLIGHT
The backlight for the LCD can be set by the user to always off, always on or
automatic (on only when the scale is in use or a key is pressed). See section
13.2.
9.0 AUTO POWER OFF
The auto power off can be set by the user to disable the feature or to a preset time interval. See section 13.3.
10.0 OPERATION
10.1 ZEROING
• You can press the [Z] key when the pan is empty to set the
zero point from which all other weighing is measured.
• When the zero point is obtained the Weight display will show the
Zero symbol.
• The scale has an automatic re-zeroing function to account for
minor drifting or accumulation of material on the platform.
However you may need to press [Z] again to re-zero the
scale if small amounts of weight are shown when the platform is
empty.
• Taring is used to eliminate the weight of a container so that only
the net weight is displayed. On the WBZ 15 scales the tare is
limited to 9.995kg. Weight above this amount will not be tared.
• Zero the scale by pressing [Z] if necessary. The zero
indicator will be on.
• Place an empty container on the platform. The weight of the
container will be displayed.
• Press [Tare] to zero the scale. The weight that was displayed is
stored as the tare value and that value is subtracted from the
display, leaving zero on the display. The Net indicator will be on.
As product is added only the weight of the product will be shown.
• When the product and container are removed the weight display
will show a negative value. If a different container is to be used,
remove this negative tare value by pressing the [Tare] once more.
Note: If the capacity of the scale is 6000g and a container weighing
2350g is used and tared, the scale can then be used to weigh the
material of up to 3650g.
To determine the weight of a sample, first tare an empty container if
used, then place the sample in the container. The Weight window will
show the weight and the unit of weight currently in use.
To hide the currency symbol, set the currency to “None”. See section
13.5.
10.4 DETERMINING VALUE OF A PRODUCT BY WEIGHT
• To determine the cost of a product by weight, it is necessary to
enter the unit price per kilogram or per 100g using the numeric
keys.
• The Weight display will show the net weight, the Unit Price
display will show the price per kg or per 100g. The Total Price
display will show the computed value for the total price.
Example:
Display will show
Weight
(in kg)
Place a container on the
scale and Press [Tare]
Place the items on the
platform
Enter the unit price. The total
price will be displayed.
• If a different unit price is required simply enter a new unit price. It
may be necessary to remove the weight to return the scale to
zero before a new value is allowed to be entered.
The scales have methods to either prevent or control unauthorised
calibration. If the Calibration Counters are enabled the scales can be
calibrated without breaking the seals, however the counters will be
incremented to identify a calibration or change in parameters.
If the scales do not have the counters enabled then access is controlled by
breaking the seals on the scale to gain access to the circuit boards inside.
See the figures on the security seal as given below.
WARNING: BREAKING OF THE SEALS MAY MAKE IT ILLEGAL TO USE
THE SCALES FOR SALES OF GOODS. CONTACT YOUR TRADING
STANDARDS OFFICE FOR FURTHER ASSISTANCE.
12.2 SECURITY SEALS
Method of sealing
Alternative method
The scale has got metallic loops on the base
and the cover, located at the right rear corner
as shown here. A metal pin or wire can be
passed through the loops and sealed using a
lead-wire seal. Ensure the seal is secured
enough to prevent removing the cover
without breaking the seal or damaging the
enclosure.
An alternative method would be to use
tamper-evident labels over the screw on the
bottom cover and over the joint between the
top and the bottom cover as shown in the
adjacent figure.
Metrology labels and additional security
measures may be added to the scale as
required by the national legislation.
NOTE: IF THIS SEAL IS BROKEN THE SCALE MUST BE RE-SEALED BY
THE RELEVANT AUTHORITIES USING EITHER THE LEAD WIRE SEAL
OR AN ACCEPTABLE SEAL BETWEEN THE COVER AND THE BASE.
WBZ..aM SECURITY SEALS: The device is equipped with a Category 1
Audit Trail. In addition a lead & wire and/or a paper security seal may be
installed. To access the audit trail press the ( 5 ) button for 3 seconds.
The display will flash the calibration counter and the configuration counter.
12.3 CALIBRATION COUNTER
The scales are sealed to prevent unauthorised calibration. However it is
possible to calibrate the scales as the software includes a counter to keep
track of how many times the scale has been calibrated and this value is
recorded on the scale so that future inspections can see if the scale has had
the counters incremented.
See the WBZ Service manual for details.
13.0 USER PARAMETERS
The user has access to the following parameters to change the way the scale
will operate. Some of these parameters can not be set by the user if they
