6.0 SYMBOLS AND INDICATORS
The LCD has unique symbols to indicate the following:
Above the LCD to the left, there are three LED’s that indicate when the weight is
below, within or over the pre-set limits during check weighing.
7.0 BATTERY OPERATION
The scale 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 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 adapter 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 an LED to indicate the status of battery
charging. When the scale is plugged into the power outlet 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 setting of
the parameter “S2 bL” in section 12.2.
9.0 AUTO POWER OFF
The auto power off can be set by the user to disable the feature or to a pre-set
time interval. See setting of the parameter “S3 AoF “ in section 12.2.
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 can 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.
Weight on the scale is above the high limit
Weight is between the limits
Weight is below the low limit
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] or [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 enabled 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 weight limit values
stored in memory. The memory holds values for a high limit and a low
limit. Either or both of the limits can be used.
NOTE:
1. The beeper and the LEDs can each be set to OFF (See section 12.1).
The LCD display will indicate whenever the weight is within or exceeds
the limits by showing ‘OK’, ‘HI’ or ‘LO’.
2. The limits can be locked for security. A Limit Password must be used to
change the limits or recall other limits from memory.
3. If a Limit Password is enabled then enter the password which will allow
access to the limits or 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 “F4 PS” 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.
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. The
limits and weighing unit will be active when the scale is turned on.
11.0 CALIBRATION
The scales are calibrated using metric weights when the weighing unit selected
is either kilograms or grams and using pound weights when the weighing unit
selected is either pounds, ounces or pounds:ounces.
To start calibration turn the scale off and then turn it on again. Press [Tare]
during the self-test. The 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".
Remove all weight from the pan and then press the [Tare] key when the
scale is stable.
After the Zero point is set, the display will show “Ld xx”. Place the suggested
calibration weight on the pan. It is best to use a weight close to the full
capacity of the scale. If the weight is different from the displayed value, enter
the value of the weight in whole numbers using the numeric entry method
(see section 4.1). The kg or the lb symbol will be on to show the active unit.
Press the [Tare] key when the stable indicator is on.
The scale will calibrate to the weight and then return to weighing.
Remove the calibration weight as soon as calibration is complete.
NOTE: If an error message “FAIL H” or “FAIL L” is shown during calibration, re-
check the calibration and repeat, if necessary. If the error cannot be corrected
contact your supplier for advice.
