7.0 BATTERY OPERATION
 The scales can be operated from the battery, if desired. The battery life is
approximately 50 hours.
 When the battery needs charging a symbol on the display area will turn on. The
battery should be charged when the symbol is on. The scale will still operate for
about 20 minutes after which it will automatically switch off to protect the battery.

 To charge the battery, simply attach the power supply module to the scale and plug
in. The scale does not need to be turned on.
 The battery should be charged for 12 hours for full capacity.
 Below 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 DISPLAY BRIGHTNESS
The brightness for the LED can be set by the user. See setting of the parameter “S2 bL” in
section 12.2.
9.0 AUTO POWER OFF

10.0 OPERATIONS
10.1 ZEROING
 You can press the [Zero] key at any time to set the zero point from which all other
weighing and counting is measured. This will usually be necessary when the
platform is empty. When the zero point is obtained the display will show the zero
indicator.
 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 [Zero] to
re-zero the scale if small amount of weight is still shown when the platform is empty.
10.2 TARING
 Zero the scale by pressing [Zero]. The zero indicator will be on. Place a container
on the pan and its weight will be displayed.
 Press [Tare] when the reading is stable. The weight that was displayed is stored as
the tare value and it is subtracted from the display, leaving zero on the display. The
stable and Net indicator will be on.
 As a product is added only the weight of the product will be shown. The scale could
be tared a second time if another type of product was to be added to the first one.
Again only the weight that is added after taring will be displayed.
NOTE:
When the container is removed a negative value will be shown. If the scale was tared
just before removing the container, this value is the gross weight of the container plus
all products which were removed. The zero indicator will also be on as the platform
is back to the same condition it was when [Zero] was pressed last.
Press [Tare] / [Zero] to remove the tare value and display zero. The Net indicator
will disappear.
10.3 WEIGHING
To determine the weight of a sample, first tare an empty container if used, then place
the sample in the container. The display will show the weight and the unit of weight
currently in use.
To change the weighing unit press the [Unit] key. The available weighing units are
the ones that are enabled by the user in the parameters section. See section 12.2.

10.4 CHECK-WEIGHING
Check-weighing is a procedure to show a display or cause a beeper to sound when
the weight on the scale meets or exceeds the values stored in memory. The memory
holds values for a high limit and a low limit. Either or both the limits can be used.
NOTE:
1. The beeper and the LEDs can each be set to OFF (See section 12.1).
2. The limits can be locked by the manager. A Limit Password must be used to change
the limits or recall other limits from memory.
3. If Limit Password is enabled then enter the password which will allow you to
change the limits or the operation of the beeper or bargraph.
Setting up Check-weighing
 Press the [Limit] key. It will show the last used high limit.
 The user will be asked for the password if the current check-weighing password
is anything other than “0000”. See the parameter “F4PS” in section 12.1. Enter the
correct password using the numeric entry method as mentioned in section 4.1. If
the password is “0000” it will display the last used high limit. The “HI” symbol will
appear on the display.
 Press [Tare] to accept the displayed high limit or enter the new high limit using
the numeric entry method (see section 4.1). When the desired value is entered
press [Tare] to accept the value. The “LO” symbol will be on. Display will show
the last used low limit. Set the low limit in the same way the high limit was set.
 Pressing the [Tare] key will return the scale to weighing, with the Check-weighing
function enabled.
NOTE: The limits are displayed in the weighing unit in use. The decimal point is fixed
at the position that is used for the current weighing unit. If the weighing unit is
pounds:ounces, the limits are entered in pounds and decimal parts of pounds. i.e.
6,0125 lb.
Mass on the balance is above the high limit
Mass is between the limits
Mass is below the low limit

© Adam Equipment Company 2018
12
10.5 LIMITS STORED IN MEMORY
If the scale is turned off it stores the last high and low limits in the memory along with
information about the weighing unit in use when the limits were stored. If the scale is turned
on again, the limits and the weighing unit will be active.
11.0 CALIBRATION
The WBW L scales are calibrated using metric weights when the weighing unit selected is
either kilograms or grams and using pound masses when the weighing unit selected is either
pounds, ounces or pounds:ounces.
Method
 To start the calibration turn the scale off and then turn it on again. Press [Tare]
during the self-test. Scale will show “P- - - - “. Enter code number “0000” using
the numeric entry method (see section 4.1) and press [Tare]. This will take
you directly to the calibration section.
 Display will show "UnLoAd".
 Press the [Tare] key; display will show “Ld xx’’ (xx- weight value). Add the
suggested weight to the pan.
 Press the [Tare] key and wait until the stability light is shown; then press [Tare]
key again.
 Display will show ‘’Pass’’ or ‘’Fail’’, then return to the weighing mode.
 Remove the calibration weight when the calibration is complete.
