1 1 Introduction
Thank you for deciding to purchase a Trooper Scale from Ohaus. The Ohaus Trooper Scale is a rugged, reliable,
electronic scale designed for easy operation.

LCD display is 1.0 inches/2.5 centimeters in height provides easy visibility when working at distances from the Scale.
Four buttons mounted on the front panel enable simple set up procedures. A menu lockout switch can be set to lock out
various functions of the Scale to prevent settings from being changed. An RS232 Interface is built in.

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.

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 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 9. 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.
