-Drafts: Fans, Heat/Air Duct, Doorways or High Traffic Areas.
-Vibrations.
-Extreme Temperature Fluctuations: Sunlight, Ovens, or Environments with Wide Temperature
Variations.
-Voltage Fluctuations. Do Not Share Current with Other Instruments that Draw Voltage in an
Inconsistent Manner such as Fluorescent Lights, Centrifuges and the like.
- Locate in an Environment with a Temperature range from 10°C to 40°C
- Place Instrument on a Level, Rigid Surface.
- Level the Instrument.
- Allow 4 Hours Warm-up on the GA-225DC & 2 Hours on the GA-164C, 224C & 314C.
- Calibrate. All GA-Series are calibrated at the factory prior to shipment. Transportation of the instrument plus
the differences in barometric pressure, humidity and ambient temperate conditions require calibration at the
point of use. Calibrate regularly to ensure accurate weighing results.
Place components inside the chamber in the following order:

AC POWER CONNECTION
- When connecting power use the original AC adapter supplied with the balance. Using an unapproved
power supply may damage the instrument and void the warranty.
- Ensure the power supply is compatible with your instrument AND the local line voltage.
- Connect the plug to the instrument.
- Connect adapter to the power outlet.
- Original Power Supply:
Input: 100-240VAC, 50-60Hz, 1.0A
Output: 15VDC, 2.0A
Polarity: Inside = +, Outside = -
ANTITHEFT DEVICE
To protect against theft place a cable through the built-in security device located on the back of the balance
below the leveling bubble and connected to a fixed point, secure with a lock.
LEVELING THE BALANCE
A slight unevenness in a balance will result in an inaccurate measurement. For accurate calibration and
weighing results level the balance at installation and any time the instrument is moved to a new location.
△In most cases leveling the balance will require several adjustment steps.
Page 3

GOOD WEIGHING TECHNIQUE
Working with precision balances requires a steady hand and an even, uninterrupted technique. Use forceps or
other suitable utensils to place the sample (and sample container) on the weigh pan as fingers are
hygroscopic.
If the balance has been idle and the draft chamber doors closed for an extended period, perform a number of test
measurements before you begin weighing to allow the atmospheric conditions (temperature, RH and barometric
pressure) inside the weighing chamber adjust to the ambient temperature outside the chamber. Rapid changes
in atmospheric conditions will have an adverse effect on the weighing result. A series of test measurements
will also help develop a smooth working rhythm. Ensure the sample and container have acclimated to the
ambient temperature of the instrument in use. Place the sample gently on the weighing pan, in the center.
At the beginning of a weighing procedure load the balance with a sample weigh close to capacity of the
balance. Place all samples in the center of the weigh pan. Use the smallest sample container possible to
reduce the influence of laminar air movement. Do not drop samples on to the pan and avoid side loading to
avoid damaging the weighing mechanism. Mechanical damage to the balance is not covered under warranty.
When working with aqueous solutions select a sample container with a small opening to minimize the effect of
evaporation. Cover the container opening when working with light volatiles. Place samples directly on to the
weigh pan.
Static electricity may have an adverse effect on weighing results such as drift and non-repeatability. When
working with samples or containers with low conductivity properties such as powers you can optimize the
performance of the balance by:
!Shield the Sample from the Weigh Pan (Metal Container and /or Foil)
!Use Anti-static Device (Brush or Ionizer)
!Increased Ambient Humidity Levels
!Anti-static Weigh Containers
Avoid weighing magnetically charged (ferrous) materials such as ion, nickel and ion. To minimize the effects
(non-repeatability) of ferrous material:
!Demagnetize the Sample
!Increase the Distance of the Sample from the Weigh Pan
!Use Below Pan Weighing (Weigh-below) Procedure
A good working knowledge of the effects from the various environmental conditions, sample matrices,
container profiles and weighing technique is paramount for high precisions weighing. Preventative measures
to minimize the effects of these conditions will provide you with optimal weighing results from your balance.

17.10.2. Returning to the weighing mode

AMBIENT CONDITION SETTINGS (cont.)
In less than ideal conditions a Filter setting of Slow combined with a Results Setting of Reliable and a Stability
Setting of Unstable will optimize the weighing performance. In good weighing environments a combination of
a Fast Filter Setting, Fast Result Settings and Stable Stability Setting will offer the faster weighing results. In
most cases the factory settings (Normal Filter, Stable Stability and Fast & Reliable Results) will provide good
weighing results. You may have to experiment with various Filter, Stability and Results settings to optimize
the performance of the balance in your environment. If you are unable to achieve good weighing results move
the balance to a more suitable environment for weighing, see Installation & Setup, page 2.
AUTO ZERO FUNCTION (Setup Key - Code P2.2.1.3)
The GA-Series offers an adjustable (Yes or No) Auto Zero Function. Enabled the Auto Zero Function will
automatically zero the balance any time it is within the auto zero tolerance (1 count).
LAST DIGIT DISPLAY (Setup Key - Code P2.2.1.4)
The GA-Series offers three settings for the Last Digit Display function:
Always
Never
When Stable
The factory default setting is Always. However, should you wish to disable the last digit, select Never. If you
prefer the last digit to appear when the balance reaches a stable reading select When Stable.
TARE WEIGHT – MANUAL ENTRY
TARE is defined as net weight. Should you wish to use a beaker, flask or some other container for your sample
simply place the container on the weigh pan and press the -T- (TARE)/INSERT KEY once. The weight of the
tared container will be stored in memory and displayed on the bottom of the display. To delete the Tare Weight
Value from the memory/display remove all samples and containers from the weigh pan and Press the -0- Key.
Please note that any container that is “tared” will decrease the remaining capacity available on the balance by
the weight of the container. If you do not use a container for weighing verify the reading is "0" before placing a
sample on the weigh pan. If not, press -0-/DELETE KEY to display "0".
AUTO TARE FUNCTION (Setup Key - Code P2.2.2)
The GA-Series offers an Auto Zero Function (Yes or No). This feature is designed to speed up the net
weighing process when measuring numerous samples that required containers or weigh boats (powders or
liquid). When using this feature make sure the weigh pan is empty and the balance is at zero weigh value.
Place weigh boat or sample container on weigh pan.
When the balance reaches stability the balance will automatically Tare and Net will be displayed in the upper
left corner of the display. Place your sample into the container and the Net weight of the sample will be
displayed. Remove the sample container and the balance will return to Zero and delete the stored tare weight
from memory. You may weigh another sample using the Auto Tare Function.
