Operation

Start up:

To start the device, just press the power button . Please make sure that there
is no weight on the scale or else the scale will be calibrated wrongly. If you want

to enter the settings mode, enter the password now.

Zeroing:

In case the scale is not calibrated to zero, make sure the scale is unloaded and

press the Zero button.

Taring:

Taring is zeroing the display when a weighing instrument is loaded. This allows
the weight readout of an empty container to be reset to zero and the net weight

to be read after filling the container.

To use the taring option, turn on the indicator and let it self-calibrate. When the
device is ready for use, place the empty container on the scale and press the
TARE button. The scale will then reset to zero. After this, the scale will display

the net weight. To cancel the TARE weight, empty the scale and press the Zero.

Accumulated Weight:

This function is used to measure the total weight of a group of items individually

and then display the total weight at the end.

To use this function turn the scale on and let it self-calibrate. When this is done,
place the weight that you want to measure on the scale. When the stable symbol
is shown on the indicator, press the M+ button on the screen to save the weight.
Do this to all the weights that you would like to measure. At the end, press the

MR button to show the accumulated weight.

To clear the accumulated weight, press M+ and MR together.

- - 5 - -

Check Weighing:

This function allows you to set a high and low range value into the indicator’s
memory. When a unit being measured is not in this range an audible alarm is
sounded to notify you. This function can be used effectively for quality control

procedures.

To set the value for the high and low range, start the machine and let it calibrate
itself. When the machine is fully calibrated press G/N and Print together. This
will display “Set H” on the screen. Pressing Zero (enter) will let you set the high

limit or press TARE (next) to select a different option.

To set the higher limit, press Zero. This is confirmed by a red light next to the
word ‘HI’ which will turn on. Then use the MR to move right and the M+ to move
left. The TARE key can be used to increment the number. To enter 65.5kg press

M+ once and then press TARE five times till the number 5 is shown. Then press
M+ once more and then press TARE five times till the number 5 again. Lastly,

press M+ and then press TARE six times till the number 6 is shown. Then press

enter to save the value. This method can also be used to set the lower limit.

To clear the high limit, go into the options and press Print. This will clear the limit.

You can also do this to clear the lower limit.

The beep function is used to set up an audible alarm on the indicator. There are

three different options available.

oH

An alarm is sounded when the weight

of the unit is inside the set range.

nG

An alarm is sounded when the weight

of the unit is outside the set range.

no

No alarm is sounded.

Animal Mode:

When using the scale to measure livestock, animal mode clears fluctuations
caused by movements providing you with a stable reading. To be able to use this
function, animal mode needs to be turned on. This can be done by entering the
settings panel during the warm-up period. Then using the TARE button search
for the “P4 OTH” option and the “Ann” option. Here you can select whether to

enable animal mode.

To use animal mode press TARE and Zero simultaneously. This will cause the

indicator to beep twice and a “HOLD” sign will show up on the screen.

- - 6 - -

Keyboard Lock:

This function allows you to lock the keyboard after 10 minutes since the last time

a button was pressed.

To enable this option, you have to enter the setting panel, and make your way
using the TARE button to the “P4 OTH” option and then the “LOCK” option. Here

you can toggle this option on and off.

When the keyboard is not in use, the keyboard is locked and if any key is pressed,
the display will show “K-LCK”. To unlock the keyboard, hold PRINT, MR, ZERO

for two seconds. This will display “ULCK” and will unlock the keyboard.

Backlight:

To adjust the backlight on the indicator, press and hold the ZERO key for 3
seconds. This will cause the display to show “setbl”. Press ZERO to enter

backlight setting. You will have three options to choose from:

bL ON

Backlight always turned on.

bL AU

Auto backlight. This turn on the backlight for only 5 seconds after a

key is pressed.

bL oFF

Turns backlight off

Press the TARE key to select the option you require. Press G/N when you are

finished to take you back to the main screen.

Auto power off:

This function is a power saving function that allows the indicator to automatically

turn off when not in use.

To use this, press and hold ZERO for 3 seconds. The display will then show
“SEtbL”. Then press the TARE key till the display shows “SEtoF” and press
ZERO. You have an option of 0/3/5/15/30 minutes to choose from. When you

Do not use this option without consulting

Millennium Mechatronics first.

CAL

This option is used to calibrate the indicator and scale
so that an accurate weight is given. There are two

options for calibration, noLin and LinEr.

noLin:

Non- linear calibration uses only one
weight to calibrate the scale. For

instructions follow the steps on page 9

LinEr:

Linear calibration should be selected if
you want to use multiple weights to
calibrate the scale. This gives a more
accurate reading than a nonlinear
calibration. To see how to calibrate in
linear mode follow the instruction on

page 9.

This resets the indicator and all parameters to factory

settings.

P8 uwb

On Bluetooth models, turns the function on/off.

The PS232 cannot be used when Bluetooth mode is

on.

Non-Linear Calibration:

To do a basic (non-linear) calibration of the scale, make your way to the “CAL”
section in the setting menu. Then select “noLin”. The screen will then display
“unLd”. At this point remove any weights on the platform then press the ZERO
key. The scale will then show the last calibration weight used to calibrate the
indicator. If this is not correct use the M+, MR, TARE keys to select the right
weight. When the correct value is entered, press ZERO to confirm and the
display will then display “load”. At this point, load the calibration weight onto the

scale. After the stable sign is displayed, press ZERO to finish calibration.

Please note that the closer this weight is to the max load you expect to measure,
the more accurate your result will be. For example, if the max load that you
expect to measure is 300kg, the closer the calibration weight is to 300kg, the

more accurate the calibration will be.

After calibration, the scale should be checked to verify the calibration and linearity
is correct. If necessary, repeat calibration. Be certain that the scale is stable

before accepting any weight.

Linear Calibration:

Linear calibration allows you to calibrate the scale over a range thus providing a

more accurate calibration. This is done by using a range of calibrating weights.

To use linear calibration, make your way to the “CAL” section in the setting menu.
Then select “LinEr”. Press ZERO to enter calibration. The display will then show
“PIN” at which point press G/N, M+, MR to enter. The display will then show
“Load0” at which point unload any weights on the platform of the scale. When

the stable sign is displayed on the screen, press ZERO to continue.

- - 10 - -

The display will then show “Load1”. At this point enter …. . Press ZERO to
continue. The display will then show “Load2”. At this point enter …. . Press ZERO
to continue. The display will then show “Load3”. At this point apply the full
capacity of the weights that you wish to measure. The device will calibrate itself

automatically and then press ZERO to finish the calibration.

If the calibration is acceptable the display will return to normal. If an error
message is shown try calibration again as a disturbance may have prevented a
successful calibration. If the problem persists, contact Millennium Mechatronics

Limited for more support.

After calibration, the scale should be checked to verify the calibration and linearity
is correct. If necessary repeat calibration, especially to be certain the scale is

stable before accepting any weight.

Battery Operation

The Indicator can be operated from the battery if desired. The battery life is

approximately 30 hours (MI101) or 80 hours (MI102).

When the battery needs charging a symbol on the weight display will turn on.
The battery should be charged when the symbol is on. The scale will still operate

for about 10 hours after which it will automatically switch off to protect the battery.

To charge the battery plug into the mains power switch. The scale does not need

to be turned on.

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

Just under the quantity display is an LED to indicate the status of battery
charging. When the scale is plugged into the mains power the internal battery
will be charged. If the LED is green the battery has a full charge. If it is Red the

battery is nearly discharged and yellow indicates the battery is being charged.

As the battery is used it may fail to hold a full charge. If the battery life becomes

unacceptable then contact your distributor.
