ITurn o and unplug the balance before connection with other
equipment.
IStrong magnetic elds and static electricity can have an adverse eect on
the balance’s accuracy. If you need to weigh magnetized or statically
charged samples, use the underweighing hook to suspend the sample
below the balance.
SERVICE
− Use only authorized parts and accessories. We are not responsible for any
modications made to the device.
− Breaking the tamper evident seal inside the scale base will void the

INSTALLATION
When selecting a location to use the balance, keep these tips in mind:
IDo not use the balance close to air vents or other sources of drafts such as
doors or windows.
IDo not expose the balance to extreme heat or cold. Keep the balance
away from direct sunlight which may cause it to heat up. Large
temperature uctuations may require recalibration of the balance.
IAvoid dust, dirt, and moisture which may accumulate on the weighing
sensors and cause a malfunction.
3. TEMPERATURE CHANGES
When moving the balance from a high temperature environment to a low
temperature environment (or vice versa), please allow the balance to
acclimatize to its new surroundings for two hours before using. Also, allow
sucient warm-up time after plugging in the balance. For warm-up times,
refer to the specications chart on page 9.

Getting Started
4. BALANCE ASSEMBLY
− Place the draft ring around the opening in
the center of the draft shield chamber.
− Place the platform on the central mounting
post.
5. LEVELING THE BALANCE
− The balance must be leveled whenever
changing locations. To adjust the level
condition, use the two adjustment feet at the
rear of the balance. Turn the adjustment feet
until the bubble on the spirit level is centered
within the bull’s-eye.
6. KEY EXPLANATION
Power Key
Turn the balance on or o.
Unit Key (Move Key)
Function 1: Change the current weighing unit.
Function 2: Move the cursor one digit to the left.
Menu Key
Function 1: Press to enter Counting Mode
Function 2: Press and hold for 5 seconds to enter the
system settings menu.
Function 3: Cycle through menu items. If there is only
one menu item, pressing will return to previous menu.
Function 4: Press and hold for 1 second to save and
exit system settings menu.

5
Getting Started
Cal Key (Enter / Zero Key)
Function 1: Press and hold for 5 seconds to enter
calibration. Press again to cancel calibration.
Function 2: Conrm menu setting.
Function 3: Remove any items from the weighing
platform then press to Zero the balance.
LNote: The balance has an automatic zero tracking (AZT) feature which
helps maintain a zero balance condition within the tolerances set in the
Zero Range Setting menu (Menu Code 4.1)
Print Key
Function 1: Send weighing data to the printer or other
device when the balance is congured to print on
demand (Menu Code 3.5 set to KEY).
Function 2: Increment the highlighted digit.
Function 3: Cycle through menu options.
Tare Key
Function 1: Tare the balance. Taring sets the weight of
an empty container to zero, so that the weight of the
contents (net weight) can then be measured.
Function 2: Exit the current menu without saving and
return to the previous menu.
Function 3: Press and hold for 1 second to exit the
current application mode (such as Density, Counting,
Animal Weighing Mode, etc).
LNote: Taring the balance subtracts the weight from the available
capacity. For example, on the PNX-203 (200g capacity), if you tare a 20g
container, you will have a remaining capacity of 180g.
