1. INTRODUCTION
NOTE: These scales are not allowed for the uses mentioned in paragraph 2a of the article 1st of the Directive
90/384/CE, therefore they are not valid for commercial transactions.
The electronic weighing scales model PB-60 are precise, rapid and versatile, for all types of use including
item counting and percentage weight functions.
The series consists of 4 different models with a capacity of up to 3,000 g.
They all have stainless steel plates on an ABS base.
All the keypads have easy-to-press keys and the displays are all large-sized LCDs (liquid crystal displays)
which are easy to read. The LCDs have a backlight and item counting function.
All scales have automatic zero setting, automatic tare, and an accumulation function that permits to save
several operations in order to have a total accumulation.

3. INSTALLATION
3.1. GENERAL INSTALLATION
The scales should be placed on a firm, even surface.
Avoid extreme temperatures. Do not place the scales in direct sunlight or near air conditioning vents.
Avoid unstable tables. The tables and the ground should be firm and not vibrate. Do not place the scales
near vibrating machinery.
Avoid unstable electricity sockets. Do not use the scales near equipment with high electrical power
consumption such as soldering equipment or large motors.
Avoid draughts such as those from fans or open doors. Do not place the scales near open windows.
Keep the scales clean.
Keep the scales dry.
These scales do not have a waterproof design (IP44) and therefore high levels of humidity should be
avoided since this can cause condensation. Avoid direct contact with water. Do not spray water on the scales
or submerge them in water. If the scales come into contact with water, measurements may become unstable
or the scales may not operate correctly. Please unplug the scales immediately from the power supply.
Do not stack anything on the scales when they are not in use.
3.2. INSTALLING THE PB-60 SERIES
Ensure the scales are standing level, by adjusting the four feet. Adjust the scales so that the bubble in the
vial is in the centre and the scales are resting on all four feet. If the scales wobble, readjust the feet.
Plug in the power supply cable in the socket on the side of the scales. Check that the power supply is as per
the scale specifications.
Put together the protective hood using the five plastic parts included with all models except the 1,5 and 3kg
range models.
Put the protective hood in position so that it fits perfectly over the scales and does not move, checking that
the small notches in the corners of the hood are positioned downwards.
Make a weight calibration as shown in paragraph 8 (Configuration) in the function Normal
Calibration (P2CAL)

4. DESCRIPTION OF KEYBOARD
DESCRIPTIONKEY
PRIMARY FUNCTION SECONDARY FUNCTION
Manual zero setting
Displays shows zero. Sets parameters and other functions.
Sets the tare of the scale, saving the
current weight in the memory as the tare
value, subtracting the value of the tare
weight and displays the result. This result
represents the net weight.
The scale enter weight control function
When the scale is in percentage mode and
the current weight value is zero, press this
key to return to normal weighing mode.
Prints results on a PC or printer using the
optional RS-232 interface.
It can also be used to add the value of the
accumulative memory if the accumulation
function is not automatic.
When the scales is in Configuration mode,
press this key to return to normal
operation.
Select kilograms, pounds, ounces, etc. as
the unit of weight when the scales is in
weighing mode.
In counting mode, this key is used to view
the weight, unit weight and number of items
when items are being counted.
This key modifies the current value of
parameters and other functions.
Press this key in the weighing mode to
change to item counting mode.
Press this key to change back from item
counting mode to normal weighing mode.
Use this key to switch the scale on and off.

5. OPERATION
5.1. MANUAL ZERO SETTING
Press at any time in order to make a manual zero setting.. When zero is obtained, the display will show
the zero indicator.
The scales are provided with a manual zero setting function in order solve minor problems in weight
deviation or accumulation of materials on the platform. If the weight exceeds total capacity by 4%, this
function is disabled.
5.2. SETTING THE TARE
Set the scales to zero using if necessary. The zero indicator will appear.
Place the packaging on the platform and a weight value will appear.
Press to set the tare of the scales. The weight that appeared on the display is saved as the tare value
and that value is deducted from the display, which returns to zero. The “NET” indicator will be activated.
When a product is added, only the product weight will be shown. The scales may be tared for a second time
if another type of product is added to the first. Again, only the additional weight will be shown after the tare
has been set.
When the packaging is removed, a negative value will be shown. If the scales are tared before the packaging
is removed, this value will be the gross weight of the packaging plus all the product that was removed. the
zero indicator will also light up because the platform returns to the same situation as when was pressed.
5.3. SAMPLE WEIGHT
In order to determine the weight of a sample, first tare the packaging and then place the sample in the same
packaging. The display will show the weight and the unit of weight in current use.
5.4. PERCENTAGE WEIGHT
The scales permit a percentage weight to be shown as 100%. Any other type of weight that is placed on the
balance will be shown on the display as a percentage of the original sample. For example, if 350 g is placed
on the scales, and the is pressed, the display will show 100.00%.
If the 350 g weight is removed from the scales and a weight of 300g is then placed on the scales, the display
will show 85.71% because 300g is 85.71% of 350g.
Note: the scales may fluctuate unexpectedly to a major degree if very small weights are used to set the
percentage weight at 100%. For example, if just 23.5 g are placed on the scales, with increasing steps of
0.5g, and the scales are set to 100%, the display will show 100.00. However, a small weight will make the
display jump to 102.12% because a 0.5g increase would imply that the weight has risen to 24.0g, i.e.,
equivalent to a 2.13% increase.
Press again to return the scales to weighing mode.

5.5. ITEM COUNTING MODE
Before starting operation, set the tare of the weight of any packaging to be used, by placing the empty
packaging on the scales. Place a certain number of samples on the platform. The number must coincide
with the item counting options: 10, 20, 50, 100 or 200 items.
When the scales display the weight, press and the item counting function will start.
The scales will show "SP 10", in order to request a sample of 10 items. Press and the display will
move through the different options: 10, 20, 50, 100, 200 and back to 10.
Press when the number coincides with the number of items used for the sample. When further weight is
added to the platform, the number of items on the display will also increase (pcs).
Press to view the unit weight /g/pcs), total weight (kg) and total number (pcs). Press to return to
normal weighing mode.
5.6. ACCUMULATION
When the scales are set in manual accumulation mode, the weight that appears on the display can be saved
in the memory by pressing (print) if the weight is stable.
The display will show “ACC ” and the total saved in the memory will be displayed for two seconds before
returning to normal mode. If the optional RS-232 interface is installed, the weight will be sent to a printer or
PC.
Remove the weight so that the scales return to zero and put another weight on the platform. Press
(print) and the display will show “ACC 2” followed by the new total.
Continue until all the weights have been added.
In order to view the totals in the memory, press (print) when the scales show zero. The display will show
the total number of items “ACC xx” and the total weight before returning to zero. The totals will also be
printed through the RS-232 interface.
In order to delete the memory, press (print), in order to see the totals and then press to delete the
memory.
