INTRODUCTION
This manual covers installation, operation and troubleshooting for the Ohaus
Analytical Standard balances, Models AS60, AS120, AS200 and AS260D. Type
approved Analytical Standard balances, Models AS60E, AS120E and AS200E are
setup to conform to OIML, EC and U.S. regulations. To insure proper operation of the
balance, please read this manual completely.
DESCRIPTIONDESCRIPTION
DESCRIPTION
DESCRIPTIONDESCRIPTION
Ohaus Analytical Standard series balances are precision weighing instruments,
designed to provide years of service with virtually no maintenance. The Analytical
Standard series is constructed using a die-cast aluminum base finished with a durable
epoxy powder paint which is resistant to commonly used acids, contains a one piece
solid-state precision electronics PC board and a seven digit LCD display which is 0.6
inches in height. All Analytical Standard series electronic balances are factory set to
measure in grams. To prevent measurements from being affected by air currents, a
draft shield is mounted to the balance. A stainless-steel spill ring is removable for
cleaning in the event of accidental spills. Power is supplied through an AC Adapter
which is available in five configurations for world-wide usage. Accessories include: an
RS232 interface kit which allows printing of results through an external computer, an
RS232 interface cable with a print switch, a security device and calibration weights.

EnvironmentEnvironment
The balance should always be used in an environment which is free from excessive air
currents, corrosives, vibration, and temperature or humidity extremes. These factors
will affect displayed weight readings.
DO NOT install the balance:
• Next to open windows or doors causing drafts or rapid temperature changes.
• Near air conditioning or heat vents.
• Near vibrating, rotating or reciprocating equipment.
• Near magnetic fields or equipment that generates magnetic fields.
• On an unlevel work surface.
Draft Shield and Spill RingDraft Shield and Spill Ring
Draft Shield and Spill Ring
Draft Shield and Spill RingDraft Shield and Spill Ring
To install the draft shield and spill ring:
1. Position the draft shield on top of the
balance as shown (approximately 30
degrees counterclockwise from the
base of the balance).
2. Looking down through the top of the
shield, line up the hole in the bottom
of the shield with the hole in the bal-
ance weighing mechanism.
3. Put the draft shield down, fitting the
holes, and turn the shield clockwise
until it locks into place.
4. Make sure that the draft shield is
firmly locked in place.
5. Install the stainless steel spill ring
inside of the draft shield with the
raised surface facing up and cor-
rectly oriented.

The AS260D offers both a fine range (lower capacity/higher readability) and a coarse

range. It remains in this range until the weight on the pan exceeds the fine range
capacity. When weight on the pan is greater than the fine range capacity, the balance
switches to the coarse range.

Checking CalibrationChecking Calibration
Checking Calibration
Checking CalibrationChecking Calibration
Before using the balance, it should be
calibrated. The balance has been calibrated before shipment, however, calibration is influenced by factors such as:
• Variations in the earths gravitational
field at different latitudes of the world.
• Rough handling.
• Changes in work location.
• Height above sea level.
• Environmental conditions.
To check the balance’s calibration, place
a known mass on the center of the pan and
read the displayed weight.
If the displayed weight differs from the
known mass by more than acceptable
limits, refer to the Calibration Menu and
the Specifications at the rear of the manual.

When weighing material or objects that
must be held in a container, O/T enables
you to store the container weight in the
balance’s memory, separate from the
weight of the material in the container.
1. Place an empty container on the pan.
Its weight will be displayed.
2. Press .
The display will show zero and the
container’s weight will be stored in
memory.
3. Add material to the container. As material is added, its net weight will be
displayed.
4. Removing the container and material
from the pan will cause the balance to
display the container’s weight as a
negative number.
The weight remains in balance memory
until is pressed again.

CALIBRATION MENUCALIBRATION MENU
CALIBRATION MENU
CALIBRATION MENUCALIBRATION MENU
Analytical Standard balances can be calibrated in two ways: Span calibration or
Linearity calibration. Span calibration resets the balance’s weighing range using two
weight values: zero and a weight value at or near the balance’s capacity. Linearity
calibration minimizes deviation between actual and displayed weights within the
balance’s weighing range. Three weight values are used: zero, a weight value within
the balances weighing range, and a weight value at or near the balance’s specified
capacity. The following table shows the sequence in which submenus appear on the
Calibration menu.

Before beginning calibration, make sure
masses are on hand. If you begin calibration and realize masses are not available,
either turn the balance off, or go through

necessary to ensure accurate weighing.

Analytical Standard Balances, Models AS60E, AS120E and AS200E may be sealed
for type approved applications. Factory sealed balances include a bracket, lead seal
and wire and security screw as shown in the figure below.
Type approved balances are Class I devices, consult local Weights and Measures
officials to determine scaling requirements. If the balance needs to be sealed in the
field, a wrench has been provided.
After the balance has been set up properly and the menus are locked out (LFT menu
selection set ON), proceed as follows to seal the balance:
1. Turn OFF and unplug the balance. Remove the Draft Shield, Spill Ring and Pan.
2. Turn the balance over and locate the access hole to the lock out switch.
3. Remove the existing screw next to the access hole and discard.
4. Place the Bracket supplied over the access hole and secure with the Security
