Congratulations and thank you for selecting a GeneMate GP-Series Portable
balance. Your balance was designed and manufactured to give you years of
service.
SAFETY PRECAUTIONS
-Check the instrument for any visible signs of damage before you apply
power.
-Ensure the power supply is compatible with your instrument AND the local
line voltage.
-Do NOT operate in Hazardous Locations. Consult your Safety Officer with
any questions or concerns.
-Make sure no liquid enters the housing. Use a damp cloth to clean the
instrument.
-Avoid exceeding/overloading the weigh capacity or dropping samples onto
the weigh pan. Weight overload and shock may damage the instrument
and void the warranty.
-When utilizing the battery operation mode, do not mix batteries. Replace all
six batteries at the same time. If the instrument will not be used for an
extended period of time, remove all batteries from the instrument. Failure
to do so may cause leakage and damage to the instrument.
GETTING STARTED
First, check the contents of your shipping carton for the following:
-GP-Series Balance
-Weigh Pan and Sub Pan
-Operation Manual
-Power Adapter
-Weigh Bowl (except GP-123MDS)
Please read your operation manual and follow the instructions for installing
your balance. Please keep your packaging for future transport and remember
to return your Warranty Card.

INSTALLATION & SET-UP
- Choose a location that is free from the influences of the following:
-Drafts: fans, heat/air duct, doorways or high traffic areas.
-Vibrations.
-Extreme temperature fluctuations: sunlight, ovens, or environments with
wide ambient temperature changes.
-Voltage Fluctuations. Do not share current with other Instruments that
draw voltage in an inconsistent manner such as fluorescent lights,
centrifuges and the like.
- Place Instrument on a level, rigid surface.
- Level the instrument.
- Allow 30 minutes for warm-up.
- Calibrate. All GP-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, at least once a week, to ensure accurate weighing
results.
AC POWER CONNECTION & BATTERY OPERATION OPTION
- 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.
- Connect the plug to the instrument.
- Ensure the power supply is compatible with your instrument AND the local
line voltage.
- Connect adapter to the power outlet.
- Original Power Supply:
Input: 110 -240 VAC, 50-60 Hz, 400mA
Output: 9VDC, 300 mA
Polarity: Inside = -, Outside = +
Battery Operation: 6 AA
Do not mix batteries. Replace all six batteries at the same time. If the
instrument will not be used for an extended period of time, remove all batteries
from the instrument. Failure to do so may cause leakage and damage to the
instrument.

LEVELING
For accurate calibration and weigh results level the balance at installation and
any time the instrument is moved to a new location.
Ensure the two rear feet are fully retracted and adjust the two front feet to level
the balance.
CALIBRATION
Calibration is required at installation (see Installation & Set-up) and at regular
intervals thereafter. Calibrate if the balance is moved to a new location.
1. Allow a 30-minute warm-up period.
2. Remove all items from weigh pan.
3. Press Tare to zero balance – if required.
4. Press CAL Key
The appropriate calibration weight for your balance (see chart below) will
“flash” on the display.
5. Place calibration weight on the weigh pan.
6. When calibration is complete the balance will display the selected
calibration weight value, beep and return to the weigh mode.
Calibrate on a regular basis, we recommend once a week, or more.
Calibration Weight Values
B-1852-120 100g ASTM Class 3*
B-1852-500 500g ASTM Class 4*
B-1852-1500 1000g ASTM Class 4*
B-1852-3000 2000g ASTM Class 4*
B-1852-6000 5000g ASTM Class 4*
* Or Better
WEIGH MODE SETTINGS
THE GP-Series offers five modes of measurement. Press the UNIT KEY to toggle between
weigh modes.
The >indicator inside the display will highlight the selected weigh mode.
GP-SERIES Weigh Modes:
GP-123MDS: g, mg, dwt, ozT, GN
All Other Models: g, dwt, oz, lb, ozT

battery operation mode. The AUTO OFF feature is deactivated at the factory.
However, should you wish to activate the Auto Off feature:
Press ON/OFF Key to turn the power off, press again to turn power on. When

TARE FUNCTION
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 TARE 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 TARE KEY to display "0".!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
CARE & MAINTENANCE
- Unplug the instrument from the power source and remove all
batteries from the battery compartment.
- Wear appropriate safety protection.
- Clean inside hood when appropriate.
- A damp cloth is recommend for basic cleaning. Do not use solvents
on the instrument housing, sub-pan, keypad, power cord and power
jack.
- Make sure no liquid enters the instrument housing.
- Handle with care to avoid damage to the weigh cell.
- Consult your safety officer with any questions or concerns.
