1. INTRODUCTION

The MPB series of electronic balances offers an accurate, fast and versatile range of general
purpose balances with counting, and % weighing functions.

There are 6 models within the MPB series, with capacities up to 6000g.
They have stainless steel weighing platforms placed on an ABS base assembly.

The keypads are light touch switches and the displays are large and easy to read liquid crystal

type displays (LCD). The LCD has a backlight.

All units include automatic zero tracking, automatic tare, and an accumulation facility that
allows the count to be stored and recalled as an accumulated total.

2. KEY AND DISPLAY

Symbol

Key

Function

ZERO

Set the zero point for all subsequent weighing. The display shows
zero

ENTER

Enter when setting parameters or other functions.

TARE

Tares the scale.
Stores the current weight in memory as a tare value, subtracts the tare

value from the weight and shows the results. This is the net weight.

%

PERCENT

To enter percent weighing function. When in percentage mode, press
this key to return normal weighing mode

SMPL

To enter Counting Mode. Also use it to return normal weighing mode

when counting mode.

MODE

Allows for selection of different weighing units, such as; kilograms,
pounds, ounce or other units

can change the current value for parameters or other functions
When in counting mode, it allows the weight, unit weight, and count to
be seen when parts counting

PRINT

To print the results to a PC or printer using the optional RS-232
interface.

It also adds the value to the accumulation memory if the accumulation
function is not automatic

ON/OFF

Turn on or turn off the power.

Description

Stable indicator. Ensure it stable indicator is on before pressing tare, sample,
percentage, or accumulation.

Low battery; charge immediately.

Tare indicator when in net weight mode.

Zero indicator

3. OPERATION

3.1 Before use

To ensure that measurements are precise, turn on the scale 10 minutes prior to use.
Recalibrate the balance when the operat+ing environment has been changed.

3.2 Zero the display

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 only be necessary when the pan is empty. When
the zero point is obtained the zero indicator will show. The scale has an automatic re-zeroing
function to account for minor drifting or accumulation of material on the platform. If small
amounts of weight are shown when the platform is empty, press the ZERO key to re-zero
the scale.

3.3 Taring

Ensure the display shows zero, and that the zero indicator is on. If needed, press the ZERO
key.

Place a container on the platform, its weight will be displayed.
Press the TARE key to tare the scale. The weight that was displayed is stored as the tare

value and that value is subtracted from the display, leaving zero on the display. The "TARE"
indicator will be on. As items are added only the weight of the product will be shown.

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 product
that was removed. The zero indicator will also be on because the platform returns to the
condition it was when the ZERO key was last pressed.

3.4 Percentage weighing

The scale will show a sample weight as 100%. Any other weight placed on the scale after,
will be displayed as a percentage of the original.

sample. E.g. If a 350g object is placed on the scale and the % key is pressed the display will
show as 100.00%. If you remove the 350g weight and put a 300g weight on the scale the
display will show 85.71%, as 300g is 85.71% of 350g.

>T

Note: the scale may jump by large numbers unexpectedly if small weights are used to set
the 100% level. For example if only 23.5g is on a scale with 0.5g increments and the scale 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 one scale division (0.5g) increase to 24.0g will be equivalent
to a 2.13% increase.

Pressing the % key will return the scale to weighing.

3.5 Parts counting

Tare the weight of any container that will be used, leaving the empty container on the scale.
Place the number of samples on the scale. The number should match the options for parts
counting, 10, 20, 50, 100 or 200 pieces. When the scale is showing weight, pressing the
SMPL key will start the parts counting function.

Press the SMPL key to begin. The scale will show "SP 10" asking for a sample size of 10
parts. You can press MODE key to select sample quantity: 10, 20, 50, 100, 200 and back to

10.
Press the ZERO key when the number shown matches the number of parts used for the

sample. As more weight is added the display will show the number of parts (pcs).
Press the MODE key to display unit weight (g/pcs), total weight (kg) or the count (pcs).

Press the SMPL key to exit parts counting mode.

3.6 Accumulation

The weight displayed will be stored in memory when the PRINT key is pressed and the
weight is stable, the display will show "ACC 1", then the total in memory for 2 seconds
before returning to normal. If the RS-232 interface is installed, the weight will be sent to a
printer or PC.

Remove the weight, allowing the scale to return to zero and put a second weight on. Press
PRINT, the display will show “ACC 2” and then show the new total.

To view the totals in memory, press the PRINT key when the scale shows 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 via the RS-232 interface.

To erase the memory press PRINT to view the totals, followed by the SMPL key to clear the
memory.

3.7 Calibration

In normal weighing mode, empty the pan, hold the MODE key for 3 second, display will
show “unload”. Wait for several seconds until the display shows “LOAD”. Put the calibrate
weight on the pan. After STABLE indicator turns on, the window will show “pass”. After self-
checking, the calibration will be complete.

Note: you can use half capacity or full capacity calibrate weight to calibrate the balance. You
don’t need key in the weight value, as the balance will automatically detect the weight.

4. BATTERY OPERATION

When the battery is low, the indicator will light up. Change the battery or use an AC adapter
after it turns on.

When battery indication show , charge the battery immediately.

The battery life is approximately 40 hours.
To charge the battery simply plug it into the mains power. The balance does not need to be

turned on.
The battery should be charged for 12 hours for full capacity.

The battery indicator flickers when it is charging. When the battery is full, the light stops flickering.

Over time, the battery may fail to hold a full charge. If the battery life becomes unacceptable then

contact your distributor.
