3.2 ZEROING THE DISPLAY
You can press the [Zero]/0
Esc
key at any time to set the zero point. When the zero point
is obtained, the display will show the indicator for zero.
The scale has a re-zeroing function to account for minor drifting or accumulation of material
on the platform. Press [Zero]/0
Esc
to re-zero the scale if small amounts of weight are still
2) Place a container on the platform, a value for its weight will be displayed.
3) Press the [Tare] ↵ key when reading is stable. The weight displayed is
then stored as the tare value.
4) The stable and “NET” indicator will show on the display.
5) Now when adding additional products, only the weight of
the current product will be shown. The scale can be tared
a second time.
Removing an object
Removing a container/ object will cause a negative value to show on the display. The zero
indicator will also appear, as the weighing platform has returned back to the same condition
as it was when the [Zero]/0
Esc
key was pressed last.
The display will automatically reset to zero if removing the object causes a negative value. If
not, press [Tare] ↵ or [Zero]/0
Esc
to remove the tare value and display zero. The Net
indicator will disappear.
3.4 WEIGHING
To determine the weight of a sample:
1) Zero the scale by pressing the [Zero]/0
Esc
key
2) Place the sample onto the weighing pan. If using a container, ensure that you tare
the container before adding the sample.
3) The display will show the weight and the unit of weight currently in use.
4) To change the weighing unit press the [Units] key. The weighing units displayed are
enabled by the user in the parameters section.
The scale can be used to count parts based on the average weight of a previously weighed
sample by following these steps:
1) Zero the scale and tare the weighing container.
2) Press the [Func] key
3) The digits [1] and [6] can be used to scroll through the
different weighing applications, press until ‘count’ appears
on the display.
4) Press the [Tare] ↵key to activate
5) Once activated, the ‘PCS’ label will appear on the top righthand side of the display.
6) Load the parts sample to be counted by pressing the
[SMPL] key, and by pressing the desired number on the
keypad e.g. 20.
7) Press [Tare] ↵ to confirm the number of parts.
8) The total number of parts will appear on the display, adding or removing parts will
adjust the parts count on the display accordingly by applying the average piece
weight to the weight of the parts to be counted.
9) During parts counting the display can be changed to show the net weight, unit weight
and number of parts by each time pressing the [Func] key.
10) To return to weighing, press [Unit] when “0 pcs” is displayed.
NOTE: If the parts are too light to measure accurately, the count may become faulty. To ensure
accurate counting the unit weight of the item should normally be at least equal to the resolution
of the scale.
Check-weighing is a procedure to display an indicator or sound an alarm when the weight on
the platform meets or exceeds the values stored in the memory. The memory holds values for
a high limit and a low limit. Either or both the limits can be set by the user.
Checkweighing Display
The LCD display will indicate whenever the weight is within or exceeds the limits by showing
“OK” (mass is between the limits), “HI”(mass is above the high limit) or “LO”( mass is below the
low limit).
Steps:
1) In normal weighing, Press the [Low Limit] key. It will show the current low limit. The
“LO” symbol will appear on the display.
2) Press the [CE] key to clear the old value and then enter the new low limit using the
numeric keys. Then press [Tare] ↵ to accept the value. If you want to reset the value
to zero, press [CE] to clear the value. The limits are displayed in the weighing unit in
use. If the weighing unit is pounds: ounces, the limits are entered in pounds and
decimal parts of pounds. i.e. 60.125 lb.
3) To set the high limit press [High Limit], the “HI” symbol will be on. Set the high limit in
the same way the low limit was set. Pressing the [Tare] key to enter the value will
return the scale to weighing, with the Check-weighing function enabled.
4) To disable the check weighing function, enter zero into both the limits as described
above. When the current limits are shown, press [CE] to clear the settings, then press
[Tare] ↵ to store the zero values.
NOTE:The weight must be greater than 20 scale divisions for the check-weighing to operate.
The indicator can store up to 10 sets of high and low limits in memory along with the weighing
units in use (including pcs and %) as well as settings for the beeper. Limits can be stored
previously stored units can be recalled.
If you are already in the check weighing mode the display will ask
if you wish to store the current limits by showing “StorE” or recall
another set of limits by showing “Recall”.
The [Lim] key can be used to toggle “StorE” and “rECALL” view
using digits 1 or 6.
Store
If you want to store the limits, when “StOrE” is displayed press the [Tare] ↵ key. The display
shows the current function “Pos”. Enter a number corresponding to the desired memory
location (0 to 9) and press [Tare] ↵ to accept. Once you have entered the desired “PoS”
number, you can then store new Low and high limits manually using the numeric keypad and
pressing [Tare] ↵ to enter.
Recall
If you wish to recall any of the pre-stored limits, press [Tare] ↵when “rECALL” is displayed.
The display shows “Pos”. Enter the number corresponding to the desired memory location (0
to 9) to be recalled then press [Tare] ↵to accept.
NOTE: If the recalled limit is for parts counting or percent weighing, the display will show the
last sample value used, ready for a new sample to be counted. If the memory location was
empty the scale will return to weighing.
3.7 PERCENT WEIGHING
The scale will use a mass on the platform as the 100% reference weight or input
a reference weight using the keypad:
1) Zero the scale and tare the container on the weighing pan once a stable weight is
displayed. If wanting to set weight manually, ensure there is nothing on top of the
weighing pan at this stage.
2) Press the [Func] key and scroll using digits [1] or [6] until ‘percent’ appears on the
display. Press the [Tare] ↵ key
3) Press the [SMPL] key. The display will now show the given weight as 100%. If no
items have been placed on the scale, pressing the [SMPL] key will change from
percentage to the pre-selected weight unit. Use the digits on the keypad to enter the
desired weight value and press the [Tare] ↵ key.
4) Removing or adding to the weighing pan will adjust the weight according to the original
weight value.
5) Press the [Func] key and scroll using digits [1] or [6] to select a different mode. Press
[Tare] ↵ to confirm.
NOTE:
1) The weight entered must be greater than 50 scale divisions.
2) The display may jump by large numbers unexpectedly if small weights are used to set
as 100% reference. For example, if only 23.5g is placed on a scale with 0.5g
increments and is set to 100%, the display will show 100.00%. However a small
change of weight will cause the display to jump to 102.13% as an increase of one scale
division (0.5g) to 24.0g will be equivalent to an increase of
2.13%.
3.8 ACCUMULATED TOTALS
The scale can be set to accumulate when a weight is added to the platform automatically or
manually by pressing [MR]. See menu structure section. The accumulation function is
available only during weighing. If at any time the weighing units are changed, the accumulated
data will be lost.
Manual Accumulation
When the scale is set to manual accumulation, the weight displayed will be stored in the
memory when the [Print] key is pressed and the weight is stable.

The display will show "ACC 1" and then the weight in memory for 2
seconds before returning to normal. The weight can be output to a printer or PC using the
RS-232 interface.
When the scale is at zero, place a second weight. When stable, press [Print M+] to
accumulate the weight. The display will show "ACC 2" for 2 seconds and then show the new
total.
Continue until all weights have been added. This can continue for up to 99 entries until the
capacity of display is exceeded.
To view the total in memory, press the [MR] key when the scale is at zero. The display will
show the total number of accumulation "ACC xx" and the total weight.
