Dual range balance**
A dual range balance is a balance that has two weighing ranges with two different resolutions.
The advantage of such dual-range platform scales is the higher resolution in the lower weighing
range without having to do without the high weighing range.

4 Structure of the platform scales

The scope of delivery includes all
necessary parts and tools to make the
balance ready for operation.

Scope of delivery:

1. Weighing platform

2. Support tube

3. Display

4. U-shape display holder

5. Tools and screws

6. Tube-diplay holder

Take out the weighing platform (7) from
the packaging and remove the
stainless steel weighing platform. (8)

It is possible to use the scales with or
without the support tube.

If you wish to use them without the
support tube, follow the steps
described under TRANSPORTATION
LOCK below and then detach the
support tube mount (10) from the
weighing platform.

If you wish to set up the scale with the
support tube, insert the cable (9)
through the tube (2).

Then use the screws (5) supplied to
fasten the support tube (2) in the
support tube mount (10).

© PCE Instruments

Now the cable (9) must be guided
through the tube-display holder (6)
and then through the U-shape display
holder (4).

Before the brackets (4) (6) are
screwed together, the cable length
must be selected in a way that the
display can be adjusted easily and
safely.

The rest of the cable (9) should be
safely stored in the support tube (2).
The cable should be bent as little as
possible to avoid cable breaks.

The display (3) must now be screwed
onto the U-shape display holder (4).
The inclination of the display can be
varied with the adjusting screws.

The cable (9) must then be plugged
into the corresponding socket (11) on
the rear of the display and screwed into
place.

TRANSPORTATION
LOCK

To protect the load cell from overload
during transport, the balance is
equipped with a transport lock. This is
in the form of 4 screws (13) located
between the upper and lower frames
(12).

In order to be able to weigh goods,
make sure that the 4 screws are
mounted at each corner with a gap of
approx. 3 … 5 mm between the lower
and upper frames.

Remember that these screws are a
mechanical overload protection device
and should not be unscrewed too far.

Finally, the balance must be aligned
horizontally. To do this, turn the
adjustable feet (14) of the weighing
platform until the level indicator (15)
shows a level position and the balance
stands stably.

Then place the weighing surface (8)
on the frame and start weighing.

After setting up the platform scales, check the

gravitational range of the place of installation in

the scales. You will find this function in the

internal menu under "C37.

To find out what the gravitational range is at your place of installation, contact your local

weights and measures office.

5 Key description

"ON / OFF"

By pressing the "ON / OFF" key, the scales can be switched ON. Pressing
the "ON / OFF" key for a longer period of time switches off the scales.

"HOLD"

With the "HOLD" key, the weight shown in the display can be frozen. By
repeatedly pressing the "HOLD" key, the display switches to normal
weighing mode.

This function is used to record the value even if the sample is no longer on
the scales, e. g. to enter it in the documents.

"TOTAL"

With the "TOTAL" key, the weight can be totalized ( + ). This key can also
be used to display the total weight ( TOTAL ).

In menu mode, the key is used to exit a function ( ESC ).

"PCS" (piece counting function)

With the "PCS" key, you can count articles of equal weight by determining
the weight.

In menu mode, the key is used to move to the left ( ← ).

"GW / NW"

With the "GW / NW" key, you can view the "GROSS / NET" weight. This
weight is the weight considering the TARE mass.

In menu mode, the key is used to move to the right ( → ).

© PCE Instruments

10

"TARE"

Press the "TARE" key to tare the displayed weight.
In menu mode, the key is used to decrease a value ( ↓ ).

"ZERO"

Use the "ZERO" function to zero the weight in the display. In contrast to
TARE, this is not taken into account for the GROSS / NET weight.

In menu mode, the key is used to increase a value ( ↑ ).

"PRINT"

With the "PRINT" key, the data can be sent to a printer or PC via the RS-232
interface.

In menu mode, the key serves as a confirmation key ( ↵ "ENTER" ).

6 Commissioning

6.1.1 Switching on and off

1. Switch on the balance:

Press and hold the key until the balance switches on. The display will then
perform a self-test and then go into normal weighing mode. As soon as the stability
symbol (see picture) appears in the display, you can start weighing.

If the balance does not respond, check the power supply to the display. If the stability
symbol does not appear, check the base and level the balance.

2. Turn it off:

Press and hold the key until the scale turns off.

6.1.2 "ZERO“

When the balance is switched on, the initial weight should always be ZERO in order to
obtain correct measurement results. For this purpose, the balance automatically filters out
any loads so that 0 kg is always shown in the display when the balance is started.

If there is no zero in the display, the "ZERO" key must be used to zero the display.
This zeroed value is not taken into account in the gross / net evaluation.

If the zero function is active, →0← appears at the bottom left side of the display.

If you wish to have the existing weight displayed after starting the scales, as is useful for
weighing containers, for example, some items must be changed in menu mode (see
menus C07 / C08 / C09 and C05 to determine the internal zero point).

6.1.3 "TARE"

This function enables the determination of the GROSS / NET weight. This means that the
scale is able to take the weight of the pallet into account.

To do this, place the empty pallet on the scales and press the "TARE" key.
If a tare weight is entered, the display shows “Tare”.

ATTENTION: The weighing range is not increased by taring, so if you have a 30 kg
scale and tare 10 kg, you only have a weighing range of 20 kg left.

© PCE Instruments

12

6.1.4 "GROSS"

When the "TARE" function is used, the weight can be shown in the display as NET or GREAT
weight, i. e. the weight with or without the pallet.

To do this, simply press the "GROSS" key and the display will show the corresponding
weight with the additional information whether it is the NET or the GROSS weight. The gross
weight appears for a short time and then automatically returns to the net weight.

NET GROSS

6.1.5 "TOTAL"

This function allows adding several weights. It is useful for monitoring the loading of vehicles, for

example. Just press the "TOTAL" key when the balance has calculated the weight. After

pressing the "TOTAL" key, the display shows "n 001".

This means that a weighing has been saved to the totalizing memory. Each time the
"TOTAL" key is pressed, the value increases. If the function is active, the message →Total←
appears in the lower part of the display.

In order to check the total, the "PRINT" and " TOTAL" keys must be pressed
simultaneously. The display will then briefly show the number of saved values, e. g. "n008" = 8
values, and then the total sum.

To exit this indication and enter normal weighing mode, press and hold the "TOTAL" key
until →CLr n← appears in the display. Here, it is possible to clear the totalizing memory by

using the "ZERO" key to change →CLr n← (Clear No) to →CLr Y← (Clear Yes) and

confirm with the "PRINT" key. Exit the function via →CLr n← (Delete No); then you can
continue with the totalizing function.

13

6.1.6 "COUNT“

This function enables you to count parts of equal weight. To do this, a unit weight must first be
entered, which is then divided by the total weight. The piece weight is saved by a reference
weighing. This means that some of the parts to be counted must first be placed on the scale and
the number of reference parts on the scale must be confirmed.

Press the "COUNT" key on the scale display. The display will now show →PCS 0←. By

pressing the "ZERO" key, the number of reference parts can now be changed. 5 / 10 / 20
/ 50 / 100 / 200 and 500 are available for selection. (The higher the number of reference parts,
the better the mean value for the piece count and thus the later count). Now the number of

previously selected reference parts must be placed on the scale and confirmed with the
"PRINT" key. The display then shows the number of pieces and the piece counting unit
→PCS←.

By pressing the "COUNT" key repeatedly, the display returns to normal weighing mode
and the unit changes from →PCS← to →kg←. You can now always use this key to switch
between the two functions. The unit weight is deleted when the balance is switched off.

If a new piece weight is to be determined, press the "COUNT" key and the "PRINT"
key simultaneously. This will take you back to the position where you can select the reference
quantity 5 / 10 / 20 / 50 / 100 / 200 or 500.

C 06
Calibrating the
scales

If the balance displays deviating weights, a new
calibration/adjustment may be helpful. However,
you should always carry out zero adjustment "C
05" before you perform this adjustment.

C 6 0 = no adjustment
C 6 1 = single point adjustment
(adjustment with only one weight)
C 6 2 = multipoint adjustment
(adjustment with up to 7 weights)
C 6 3 = *****************

Before adjusting the balance, make sure that it
is level on a solid surface and that the cells and
platform are free. (transport lock, etc.)

Then the weights should be prepared for the
adjustment - we recommend at least 2/3 of the
total load as adjustment weight.

Multipoint adjustment is the best way to achieve
the highest possible accuracy of the balance.

If the balance changes location frequently, the
gravity settings under "C36" and "C37" should
be observed.

Enter the
function "C 06"

or mains adaptor: 9 V / 1.2 A / outside ( - ) / inside ( + )

Battery operation is not possible for displays / scales with analogue output or potential­free contacts. The power supply is then provided by a 12 V / 1.2 A / external ( - ) / internal
( + ) mains adaptor.

Cell connection

The display can be connected with up to 6 cells (4 or 6-wired) of a maximum of 350Ω.

+Exc = red cable
+Sig = green Cable
Shie = black cable (with shrinking tube and

small lettering)

-Sig = white cable

RS 232 interface / D-SUB 9 female

You can connect the balance to various external devices via the RS-232 interface.
ATTENTION:

Observe the pin assignment of the connection cable and the interface parameters.

34

If the PC in use does not have an RS-232 interface, you can use a USB converter to establish a
direct connection between the balance and the PC (without an intermediate cable).

The platform scale has a bidirectional RS-232 interface. This means that you can use query
commands to control the scale via this interface. For example, you can use a PC software to
query the weighing result from the scales for and process it as intended by your software.

9 Connecting the balance to the PCE-BP1 printer

First check the settings of the printer. Please lift the cover of the printer and remove the paper
roll. Below the paper roll, there are toggle switches which must be set to ON/OFF as follows
(see picture). After the settings have been made, the printer must be restarted so that the
settings are applied.

Then connect the printer to the display of the balance via the RS-232 interface.
The cable supplied with the printer must be used.

Then the display of the balance checks the settings.

To enter the internal menu, press the "HOLD" key and the "PRINT" key
simultaneously. The display will then show →C 01←.

The "ZERO" and "TARE" keys are used to change the number.

The "COUNT" and "GROSS" keys change the position.

The "PRINT" key confirms the entry or enters the function.

The "TOTAL" key exits the function.

Now the CONFIG.TXT file from the USB pen drive must be adapted. To do this, simply insert
the USB pen drive supplied into the PC and open the CONFIG.TXT file.

Especially the marked points have to be considered.

1. You have set the baud rate in the balance to 9600, so the baud rate here must also be 9600.
Please adjust if necessary.

2. Depending on the selected data transfer, entries must also be made here.
In example 1, data is shown if data transfer by keystroke is selected in the balance.

It is important that the query command in "SI" is set and INTERVAL = 0

Example 2 shows data to be set if the balance is to be queried by the PCE-USM. Here,
"COMMAND = P" is the request command and "INTERVAL=10" is the time intervals in seconds
in which the queries are to be made.
