Important notice for verified weighing instruments
Weighing Instruments verified at the place of manufacture bear one of the preceding mark on the packing label and
the green ‘M’ (metrology) sticker on the descriptive plate. They may be put into service immediately.
Weighing Instruments to be verified in two stages have no green ‘M’ (metrology) on the descriptive plate and bear one
of the preceding identification mark on the packing label. The second stage of the initial verification must be carried
out by the approved service organization of the authorized representative within the EC or by the national weight &
measures (W+M) authorities.
The first stage of the initial verification has been carried out at the manufacturers work. It comprises all tests according to the adopted
European standard EN 45501:1992, paragraph 8.2.2.
If national regulations limit the validity period of the verification, the user of the weighing instrument must strictly observe the re-verification
period and inform
the respective W+M authorities.

EN-5
Trooper Scale
2.2 Selecting the Location
The Scale should be used in an environment which is free from corrosives, vibration or temperature extremes. These
factors will affect displayed weight readings. The Scale should be located on a stable level surface and kept away from
vibrating sources such as large machinery. Maximum accuracy will be achieved when the area is clean and vibration
free.
2. INSTALLATION
2.1 Unpacking and Checking
Open the package and remove the instrument and the accessories. Check the completeness of the delivery. The follow-
ing accessories are part of the standard equipment of your new Scale.
Remove packing material from the instrument.
Check the instrument for transport damage. Immediately inform your Ohaus dealer if you have complaints or parts are
missing. Your Trooper Scale package should contain:
• Trooper Scale
• Warranty card
• AC power adapter
• Instruction Manual
• Lead seal for weights and measures sealing
Store all parts of the packaging. This packaging guarantees the best possible protection for the transport of your
instrument.
NOTE: Remove the two shipping screws if present on top of the unit.
2.3 Connecting Power
2.3.1 Battery Installation
Remove battery cover and insert 6 Alkaline C-type batteries into the battery holder making sure that the batteries are
properly orientated (correct polarity).
NOTE: It is recommended that when the Trooper Scale is operated from batteries, the Auto-Off Timer feature be turned
on to extend battery life. When setting up the Scale, refer to Intial Setup, Readout menu, paragraph 4.4.4.
2.3.2 AC Power
Connect the AC power cord from the Scale and plug into a convenient power outlet.
NOTICE:
The socket/outlet must be installed near
the equipment and shall be easily accessible.

EN-6 Trooper Scale
2.3.3 Leveling the Scale
Exact horizontal positioning and stable installation are prerequisites for repeatable results. To compensate small
irregularities or inclinations at the location, the instrument can be leveled.
For exact horizontal positioning, the Scale is equipped with a level indicator located at the rear.
Adjust the leveling feet until the air bubble in the indicator is centered.
NOTE: The instrument should be leveled each time its location is changed.
2.3.4 Stabilization
Before initially using the Scale, allow time for it to adjust to its new environment. Recommended warm up period is
five (5) minutes.
3. OPERATION
The Trooper Scale has been factory calibrated and is ready for operation. You can operate the scale at this point using
the factory default settings. You can check the default menu settings on page 11. All bolded items on the menu are the
factory default settings. The scale will operate in the default mode. If you want to change the settings, continue with
Section 4, Setup.
When the Scale is positioned for operation, follow the operational procedure outlined next.

3.4 Tare Operation
When weighing material or objects that must be held in a
container, taring stores the container weight in the Indicator’s
memory. To store the container weight, proceed as fol-
lows:
Place the container on the scale. Sample shown is 2kg.
Press TARE button. Scale is tared andshows Net
weight.
3.1 Turning On Scale
Press and hold ON/ZERO/ OFF button until the LCD dis-
play appears, then release ON/ZERO/
OFF button. The
display momentarily displays segment check, the soft-
ware revision of the Scale and then goes into a weighing
mode.
3.2 Turning Off Scale
To turn the Scale off, press the ON/ZERO/ OFF button until
OFF is displayed.
3.3 Zero Operation
Using a
shortshort
shortshort
short duration press, press ON/ZERO/ OFF but-
ton to zero the Scale. The display acknowledges by indi-
cating the selected measuring unit followed by a zeroed
display.
NOTE: Stable cursor must be lit to accept zero operation.

3. OPERATION (Cont.)
3.5 Gross/Net/Tare Recall Operation
When a container has been placed on the platform and
tared, it's weight is stored in memory. Adding material to
the container is shown as NET weight. The gross weight is
a combination of the tared weight and the material. The G/
N/T/
MENU button allows switching between GROSS, NET
and TARE weights.
Repeatedly press (short presses) the G/N/T/
MENU but-
ton to cycle through Gross, Tare and Net readings. The
sample illustrations indicate a tare weight of 2kg simu-
lating a container, a net weight of 8kg which would be
the material in a container and a gross weight of 10kg
which is the total weight of the container and material.
After 3 seconds, display returns to Net weight.
Tare
3.6 Unit Switch Operation
To switch measuring units, proceed as follows:
Press and hold PRINT/
UNITS button until display
changes to selected measuring unit. Depending on which
units are enabled in the menu, you have a choice of g,
lb, kg or oz. The display sample indicates 8kg load
changed to lbs shown as a net weight because a tared

AVERAGING LEVEL
Averaging level compensates for vibration or excessive air
currents on the scale platform. During operation, the Scale
continually takes weight readings from the load cell. Suc-
cessive readings are then digitally processed to achieve a
stabilized display. Using this feature, you specify how much
processing you need.
HI and LO settings are available.
HI setting:
More processing, greater stability and
slower stabilization time.
LO setting:
Less processing, less stability and faster
stabilization time.
