3.0 SET UP
3.1 UNPACKING AND SETTING UP YOUR ANALYZER
Remove the balance from the packing by carefully lifting it out of the box.
Inside the box you will find everything needed to start using the analyzer-
AC power cable
Pan Support
Stainless Steel Lower Chamber Insert
Sample Pan Lifter
Sample Pans (Qty 10)
Spare Fuse 5A, Time Lag, High capacity
This User Manual
IMPORTANT:
Before applying power make sure the balance is configured for the power in
your area. The analyzer will have a label on the rear panel showing the
voltage required: 115VAC (±10%) or 230VAC (±10%). If the label does not
match your power do not attempt to use the analyzer, damage to the balance
could result.
The balance should be positioned to allow easy access to the power
connection on the rear panel. Ensure the power cable is fully engaged to
ensure safe operation.

3.2 ASSEMBLING
THE ANALYZER
For best performance, let the analyzer warm up for 30 minutes before using.
Locate the balance on a solid
surface, free from vibration with
good ventilation around it.
Place the lower reflector (1) into
the base of the weighing chamber
Gently place the pan support (2)
into the access hole. Rotate to
position.
Place the sample pan lifter (3) into
the weighing chamber, rotate so
the tangs on the lifter do not
interfere with the pan supports
and the handle exits the chamber
using one of the gaps in the
cover.
Place an empty aluminium
weighing tray (4) on the pan
support
Level the balance using the
adjustable feet and spirit level
For some applications it is desirable to run the analyzer in a dummy run to
warm up the weighing chamber and the surrounding area before doing the
actual test. See section 14 for other ideas to help ensure accurate test
results.

3.3 LEVELING THE ANALYZER
After placing the balance in a suitable location,
level it by using the spirit level on the rear of the
analyzer. To level the balance turn the two
adjustable feet at the rear of the analyzer until
the bubble in the spirit level is centered.
3.4 WARM-UP TIME
Attach the power supply cable to the connector
on the rear of the analyzer. The master power
switch is on the rear panel, next to the power
cable. Turn the power on.
The display will indicate the serial number and
the software revision number followed by the
capacity. Next the analyzer will run a self-test by
displaying all segments. The display will then
show zero weight accompanied by the 0
symbol.
Before you start weighing, wait for the analyzer to achieve a stable internal
temperature. In addition it may be necessary for some material test to
preheat the weighing chamber so that the delay to reach operating
temperature is minimized.
A stable sign ~ is shown when the balance is in
stable condition. It will turn off if the reading is
not stable.
Exact zero is shown when the “0 “ symbol
is on to the left of the display area.

3.5 LOCATING AND PROTECTING YOUR ANALYZER
In order to keep your analyzer functioning at its best we suggest that you do
the following:
Avoid extremes of temperature. Do not place in
direct sunlight or near air conditioning vents.
Make sure there are no heat sensitive or
flammable materials above the analyzer. The
exhaust from the weighing chamber can be very
hot.
Make sure the analyzer is located on a strong
table and free from vibration.
Avoid unstable power sources. Do not use near
large users of electricity such as welding
equipment or large motors.
Keep free from vibration. Do not place near
heavy or vibrating machinery.
Avoid high humidity that might cause
condensation. Keep away from direct contact
with water. Do not spray or immerse the
analyzers in water.
Do not place near open windows, air-

The rear panel has connectors for the data interface, fuse holder, security
lock location and power supply input.
5.1 POWER
Make certain your balance is compatible with the power supply in your area.
If the voltage is not the same the analyzer can be damaged. Contact your
supplier if you require assistance.
The power connection uses a standard IEC C13 socket on the cable with a
plug suitable for the location. Do not use adaptors if the plug does not match
your power supply.
The fuse should only be replaced with a time lag type fuse with high breaking
capacity, 5Amp current rating. The fuse is a standard 5 x 20mm size. To
replace the fuse remove all power from the analyzer, unscrew the fuse holder
cover to extract the old fuse, replace with a new fuse. If the fuse should blow
again, the analyzer must be serviced by a qualified service representative.
There are no user serviceable parts inside. Contact your supplier.
5.2 DATA INTERFACE

6.0 BASIC OPERATION
When first turned on the balance will act as a basic balance showing grams
weight on the display.
If a passcode has been set to limit access to the weighing functions of the
analyzer the display will show “PASSCODES”. The display will change to
show 7 digits set to zero with the rightmost digit flashing. Use the numeric
entry method (see section 4.1) to enter the code. Make sure to enter the
correct passcode to continue. See the Section 10.1.4 for details.
While in the weighing mode the test conditions for a drying test can be set.
6.1 SETUP OF METHOD
•The balance is set to perform a drying test using a method determined
by the user. The drying method can be input by using the keyboard or
entered from a PC using the RS-232 interface.
Regardless of the method used it will be necessary to program the analyzer
with the following:
Type of test:
•% moisture =100 * ((initial mass - dry mass)/initial mass)
•% solid =100 * (dry mass/initial mass)
•% moisture vs. dry weight =100 * ((initial mass - dry mass)/dry mass)
Also called ATRO Moisture
•% solid vs. dry weight = 100 * (Initial mass/dry mass)
Also called ATRO Solid
ATRO Moisture or Solid test are special applications specific to some
industries. %Moisture and %Solid are the more common calculations.
Heat Control
•Single temperature, heat to a set temperature (50-160ºC).
