re-charged, this symbol will be flashing.

The weight is stable.

The keys perform the following functions:

This key is used during setting of the user functions.

[High/Low/

Mode]

[Unit/]

It is also used during setting of the High and Low Limits for
check-weighing facility and for setting the alarm function.

This key is used to change the weighing units while the scale
is in the weighing mode.
It is also used for advancing the digit while the scale is in the
setting mode.

This key is used to deduct the weight of the container from the
gross weight and thus to display the net weight only.

[Tare/]

[Zero/ ]

It is also used to increment the digit while the scale is in the
setting mode.

This key is used to reset the zero position for accurate
weighing while the scale is in the weighing mode.
It is also used to decrease the digit during the setting mode.

2.2 POWER SUPPLY

• Power can be supplied using an internal re-chargeable battery

provided within the indicator case or the main power

• If the battery is low on charge, will be displayed. The battery
needs to be re-charged immediately. While the battery is getting
re-charged, this symbol will be flashing.

• With the internal re-chargeable acid battery, the battery life is
approximately 60 hours. The battery life will vary depending on
the use of the backlight.

3.0 OPERATIONS

3.1 POWER

• Attach the main power cord to the power supply. The indicator
will charge the internal battery whenever it is connected to the 220
VAC power supply.

• To turn on the scale, press the power switch on the right back of
the indicator.

• A message “
with a beep, ensuring all the segments are working. The message
“Uolt xx” will be shown before the display goes to zero. The value
of “xx” is an indication of the percentage of charge of the internal
battery.

SYS UP

SYS UP

SYS UPSYS UP

” will be displayed and then will run a self test

• To switch off the indicator press the power switch again.

3.2 ZERO FUNCTION

• For accurate weighing, zero the display by pressing the key

[Zero] with nothing on the platform of the scale.

• The zero indicator 0 will be on.

3.3 TARE FUNCTION

• When the scale has a container on it press the [Tare] key.

• The Tare indicator will be on.

• The display will show zero. If it does not show zero, press the

[Zero] key.

• To clear the tare, remove the container and press the [Tare] key
again. Press [Zero] to switch off the Tare indicator.

3.4 UNIT SELECTION

• The indicator can be set for different units by pressing the [Unit]
key. The options are kilogram, gram, tonne, pound and ounce.
They can be enabled as needed (see section 6.2). Kilogram is
always on.

3.5 WEIGHING

• Place the sample on the scale platform. The weight will be
displayed in the selected Unit.

• Wait till the stable indicator is on for accurate weighing.

3.6 CHECK WEIGHING

Check-weighing is a procedure to sound an alarm when the weight of the
sample on the scale meets or exceeds the pre-set Low and High values
stored in memory, by using the [Mode] key.

To set the High and Low values, follow the procedure given below-

• Press the [Mode] key. The display will show “000.00 HI” with the
first digit flashing for setting the High value. Use the [Unit] key to
advance, the [Tare] key to change the value of the flashing digit.
Press [Mode] again to confirm the value.

• Press the [Mode] key again. The display will show “000.00 LOW”
with the first digit flashing for setting the High value. Use the
[Unit] key to advance, the [Tare] key to change the value of the
flashing digit. Press [Mode] again to confirm the value.

• Press [Mode] once again to return to normal weighing.

• Once the check weighing Limits are set and the alarm function is

active, a beep will sound slowly when the sample weight is below
the Low Limit. The beep will sound quickly if the weight is above
the High Limit. If the sample weight is in between the Limits, the
beep does not sound.

3.7 ALARM

3.7.1 Over-load alarming

• When the sample weight on the scale is over the maximum capacity the
beep will sound and the display will show “EEE----“.

• Remove the weight immediately to avoid any damage to the scale.

3.7.2 Low-load alarming

• If the platform is not placed on the scale the beep will sound.

• Place the platform on the scale before starting to weigh.

3.7.3 Low battery alarming

• When appears on the LCD, re-charge the battery.

• During re-charging, the symbol will keep flashing and it will disappear

once the charging is complete.

• If this symbol appears along with the beep, stop using the scale at once
and re-charge the battery immediately to avoid any damage to the
battery.

4.0 USER PARAMETERS

The following parameters can be set by the user by entering the function
setting mode. Press the [Tare] key while switching on the indicator. The first
parameter will be displayed along with the settings done previously.

• The available parameters can be cycled through by pressing the

[Mode] key.

• Not all parameters may be enabled. Some parameters may be set
during the initial configuration and the user is not given access to
them. In this case those will not be seen when the [Mode] key is
pressed. To use any of the parameters see the corresponding
section of the manual.

• Switch off and switch on again to return to weighing.
