load cell to the base assembly.
The indicators offer:
•Simple operation
•Zero Tracking
•Selectable automatic backlight
•Check-weighing with low and high limits
•RS-232 interface as standard
•Selectable communication mode
•Operation from internal rechargeable battery or mains power
•4 weighing units (kg, g, ounce & pound)

2.1 KEYBOARD AND DISPLAY
The AE-301 indicator has the following symbols:
The scale is at zero
Net A weight has been tared, the display is showing the net weight
The battery symbol showing the state of charge. While the battery is
being re-charged this symbol will show four bars
The weight is stable.
The keys perform the following functions:
[High/Low/
Mode]
This key is used during setting of the user functions.
It is also used during setting of the High and Low Limits for check-
weighing facility and for setting the alarm function.
[Unit/]
This key is used to change the weighing units while the indicator is
in the weighing mode.
It is also used for advancing the digit while the indicator is in the
setting mode.
[Tare/]
This key is used to deduct the weight of the container from the
gross weight and thus to display the net weight only.
It is also used to decrease the digit while the scale is in the setting
mode.
[Zero/ ]
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 the increment 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 from mains
power.
• If the battery is low on charge the symbol on the LCD will
show just one bar meaning the battery needs to be re-
charged immediately. While the battery is being re-charged,
this symbol will show four bars.
•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
2.3 LOAD CELLS
•To connect the AE 301 indicator to a new base it is
necessary to connect the load cells properly. Then set the
parameters for the weighing system.
•User should ensure the load cells are correct for the purpose
and the signal from the load cell is correct.
•Note that it may not be possible to measure the voltage
signal from the load cell with all DVM. Some DVM will
measure the Excitation and signal voltage while others will
not. Try measuring the excitation voltage to determine if your
voltmeter will work.
CONNECTING TO LOAD CELLS
The AE 301 is supplied with a connector to connect an external
load cell.
The load cell can be connected in either a 4 or 6-wired
configuration. The standard connection is 4 wired.
Pin 1 Excitation +
Pin 2 Excitation –
Pin 3 Signal +
Pin 4 Signal –

3.0 OPERATIONS
3.1 POWER
•Attach the mains adaptor to the power supply and plug the
connector into the socket on the Indicator The indicator will
charge the internal battery whenever it is connected to the
220VAC power supply.
•Push the ON/OFF switch at the back right hand side of the
indicator to the ON position to power up.
•Push the ON/OFF switch at the back right hand side of the
indicator to the OFF position to power down.
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 Net will be shown.
•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, pound and

3.5 WEIGHING
•Place the sample on the scale platform. The weight will be
displayed in the selected Unit.
•Wait until the stable indicator is displayed 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 the memory.
To set the High and Low values, follow the procedure given below-
• Press the [High/Low] key. The display will show “000.00 HI”
with the first digit flashing for setting the High value. To set
your limit, use the [Unit] key to advance the flashing digit, the
[Tare] key to decrease the value of the flashing digit and the
[Zero] key to increase the value of the flashing digit .
•The display will now show “000.00 LOW” with the first digit
flashing for setting the Low value. To set your limit, use the
[Unit] key to advance the flashing digit, the [Tare] key to
decrease the value of the flashing digit and the [Zero] key to
increase the value of the flashing digit . Press [Mode] again
to confirm the value and the display will return to normal
weighing mode.
•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 “Err“.
•Remove the weight immediately to avoid any damage to the scale.
3.7.2 Low-load alarming
•If the top pan is not placed on the scale the beep will sound.
•Place the top pan 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 show four bars.
•If this symbol appears, 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 when
settings are complete.
