3.0 SAFETY PRECAUTIONS
All safety messages are identified by the following words "WARNING" and
"CAUTION". These words mean the following:
WARNING Important information to alert you to a
situation that might cause serious
injury and damage to your property if
instructions are not followed.
CAUTION Important information that tells how to
When using the balance, following safety precautions should always be followed
WARNING
Use the AC adapter designed by the manufacturer for the balance. Other
adapters may cause damage to the balance.
CAUTION
• Avoid installing the balance in direct sunlight- this may cause poor
performance or malfunctions.
• Do not mix different type of batteries. Replace all the batteries at the
same time.
• If the balance is not to be used for a long period of time, remove all
batteries from the battery compartment to avoid leakage which may
cause damage to the instrument.
• Avoid overloading or dropping material onto the platform as that
could damage the balance.
• Do not spill liquids on the balance as it is not water-resistant. Liquids
may damage the case and if it gets inside the balance it may cause
damage to the electronics.
• Material that has a static electric charge could influence the
weighing. Discharge the static electricity of the samples, if possible.
Another solution to the problem is to wipe both sides of the pan and
the top of the case with an anti-static agent.

5.0 PREPARATION
5.1 SETTING UP THE BALANCE
CAUTION
• Avoid installing the balance in direct sunlight that may cause poor
performance or malfunctions.
• Place the balance on a firm weighing table so that the balance is
levelled. The balance will not perform accurately when it is not
levelled.
• Level by adjusting the feet to centre the bubble in the spirit level.
• Remove the shipping protection screw and round cover as shown
below using the Allen key supplied in the box. (It is advisable to keep
the shipping protection screw and the round cover along with the
packing box for using during shipping to another location in future).
Shipping protection screw
Round cover around the screw
• Place the platform (comes separately packed) in the receptacles on
the top cover. Place the stainless steel pan. (See the diagram on
page 5).
• Do not press with excessive force as it could damage the load cell
inside.
• Place the balance on a firm and flat surface for accurate weighing.
5.2 INSTALLING BATTERIES AND POWER
Remove the battery compartment cover and insert six batteries (R6P/LR6
/AA size) into the battery compartment. Take extreme care in placing the
positive and negative polarities correctly.
Alternately, plug in the AC adapter into the socket at the rear of the
balance. The AC input requirement could be 100, 120, 220, 230 or 240
Volts (50/60Hz) depending on the location where it is used. Verify the
adapter is correct.
6.0 WEIGHING
6.1 BEFORE WEIGHING
Be aware of the Automatic power-off function. If the Automatic power-off
6.2 WEIGHING PROCEDURES
function is active it will turn the balance off after 2 minutes of inactivity.
• Press [On/Off] to turn on the balance.

• Select the weighing unit with [Unit].
Press [Unit] to select a weighing unit, eg. "g" / "ct" / "oz" or "dwt" .
Once the unit has been selected, the weight will be displayed in the
selected unit and a symbol for the weight will be shown.
• Start weighing
• If you do not use a container for weighing
Verify the reading is "0.00". If not, press [Tare] to display "0.00".
Place the objects on the weighing pan to weigh.
When the reading becomes stable, the stable indicator is displayed.
• If you use a container for weighing
Place an empty container on the pan.
Wait for the stability indicator to be displayed and press [Tare].
Place the objects to be weighed in the container.
When the reading becomes stable, the stable indicator is displayed.
Only the net weight is displayed.
7.0 SETTING OF FUNCTIONS

• Press [Tare] first, then press [On/Off], while keeping [Tare]
pressed. The display will show "A-On" or "A-OFF".
7.2 SELECTION OF AUTO SHUT OFF MODE
• When the display shows "A-On" or "A-OFF" press [Unit] to select auto
shut off setting mode.
• Press [Tare] to choose "On" or "OFF" mode,
"A-On" means auto shut off function is active.
"A-OFF" means this function is inactive.
• Turn off the power and then turn it on again to enter the normal
weighing mode. The delay time will be about 2 minutes.
7.2 SELECTION OF AUTO BACKLIGHT MODE
• Next press [Unit] to enter the backlight setting mode. The display
will show "L-On" or "L-OFF".
• Press [Tare] to choose "On" or "OFF" mode,
"L-On" means auto backlight function is active.
"L-OFF" means this function is inactive, i.e. backlight is shut off.

weighing mode.
7.3 UNITS SELECTION (FOR AQT 200 ONLY)
• Next press [Unit] to enter the units selection mode, the display will
show "On ct".
• Press [Tare] to select On or OFF.
On means this weighing unit is enabled,
OFF means this unit is disabled.
• Press [Unit] to go to the next weighing unit. The following weighing
units can be selected in sequence.
ct – oz – dwt – tL.H – tL.S – tL.T (Note: g is always activated)
• Turn the balance off and back to on again to return to normal
operation.
NOTE: It is recommended that the balance is used in a location with
sufficient light so that the backlight function can be turned off to
maximise the battery life.
8.0 CALIBRATION
• Calibration may be required when the balance is initially installed or
if the balance is moved from a location.
• With time and use, mechanical deviations may occur. Therefore
calibrate the balance whenever the best accuracy is required or
when any deviation is observed during weighing a test weight.
• Before calibrating it is necessary to have the proper calibration
weights. The weights should be known to an accuracy that is
appropriate for the balance being calibrated, for example, OIML
Class M1 type or ASTM E617 Class 4. If you do not have proper
weights do not attempt calibration.
