1. I NTENDED USE

PUE 5.15, PUE 5.19 terminals are designed for scales that work with strain
gauge load cells. The terminals’ housing is made of stainless steel. PUE

5.15, PUE 5.19 are intended to be used in industry.
A big colourful screen of the terminal with a touch panel makes the software
operation much more comfortable since there is no need to use a keyboard.

PUE 5 terminal is a genuine device that consists of two units: the computer
and the weighing module, placed in one housing. Both of these units are
connected via an internal interface. The possibility of using common
operating systems allows external companies to create its software or to use
the existing one.
Such common devices as PC computers can be used with the terminal,
which is a great advantage while creating a network. Individual workstation
with the PC device is as well possible.
The terminal can work with 4 weighing platforms (option).

instructions. Use the device as intended.

B. The weighed products should be placed in the central part of a scales

pan.

C. Do not use any means causing corrosion for cleaning.

D. The gross mass of weighed products must be lower than the scales

maximum load.

E. Great loads shouldn’t be left on the scales pan too long.

F. In case of a failure the device power supply should be instantly switched

off.

In order to zero mass readout of a presently selected platform the user has

to press

button which is to be found in a weighment display of a

„MwManager” program (the top right hand corner) or he has to initiate
zeroing function defined for a given input (See point 9.5.3 of this manual).

On a display mass readout with zero value will be shown next to symbols:

and .
Zeroing means estimating a new zero point which will be recognized by scale
as an exact zero. Zeroing is possible only when display states are stable.

Caution:

Zeroing a display state is possible only within the range upto ±2% of the
maximum scales load. If zeroing value is greater than ±2% of the maximum
load then the message Err2 is displayed.

10.3. Taring

To estimate net mass for a presently selected platform the user needs to put
packaging on a device and wait for a readout to stabilize, next (s)he may

press button

. The other possibility is to initiate tare function defined

for a given input (See point 9.5.3 of this manual).
On a display mass readout with zero value is be shown next to symbols : Net

. The scales has been tared.

i

- 38 -

While using tare function the user has to pay attention to maximal weighing
range. It cannot be exceeded. The readout which is a sum of tarred mass will
be displayed after the load and the package have been taken off. Minus sign
will be seen in front of a displayed value.

Caution:

Taring process cannot be executed when a display shows minus mass value
or a zero mass value. In such a case the message Err3 is displayed.

10.4. Weighment for dual range scales 1st range weighing proceeds to 2nd range weighing automatically without

any interference of the user (immediately after the 1
maximum has been exceeded). The 2

11.1. Autozero func tion

For ensuring accurate balance readaouts „AUTOZERO” function has been
introduced. This function automatically controls and corrects zero readouts.

When this function is active several measuring results are compared at
regular intervals. If value differentiating these results is lower than declared
AUTOZERO range, e.g. 1 reading unit, than zeroing is automatic. Markers of
stable result -

and zero readout - are displayed.

When AUTOZERO function is active each measurements start with an exact
zero which is useful. Although there are cases when this function can be a
drawback. One of such examples might be putting load on a pan very slowly
(e.g. pouring the load). Zero readout correction system in such a case might
distort readout of a real mass of the load.

Procedure:

• Enter user parameters window

,

• Select or unselect <Autozeroing> parameter

- autozeroing function on

- autozeroing function off

11.2. Median filter

12. CHECKWEIGHING

Checkweighing is a function that enables precise weighment of a sample for
which minimum and maximum weighing threshold, so called checkweighing
thresholds, have been determined (LO – to little mass of the sample, HI – to
big mass of the sample, OK – correct mass of the sample).

These states are presented through light signaling or through steering of
peripheral devices systems.

Fig.26 States range for checkweighing function

Caution:

Starting procedure of checkweighing function and its signaling have been
presented in point 9.6.2 of this manual.
