You have purchased a quality precision weighing instrument that
requires handling with care.
Read entire contents of this Operation Manual prior to operating
your new Denver Instrument balance.
Disclaimer Notice
Calibrate your balance using a reference weight of the appropriate
tolerance (class). An instrument can be no more accurate than the
standard to which it has been compared. For assistance in the selec-
tion of reference weights, please contact the factory.
Caution!
Changes or modifications not expressly approved by the manufac-
turer could void the user’s authority to operate this equipment.
Warning
Never lift balance by the weighing pan as this may cause
damage to internal mechanisms.
Always lift and transport the balance by its base, including
removal from packing materials!

Getting Started
• Avoid lengthy exposure to extreme heat or cold. Your balance works
best when operated within the temperature limits listed in the specifica-
tions. Always allow the unit to acclimate to a stable temperature before
calibration.
• Allow at least 30 minutes of warm up time before starting weighing oper-
ation or calibration to give internal components sufficient time to stabi-
lize.
• Keep your operating environment as clean as possible. Electrostatic
fields, gravitational fields, dust, dirt, moisture, vibration, air currents, and
proximity to other electronic equipment can all have an adverse effect on
the reliability and accuracy of your unit.
• Handle with care. Carefully set weighing pan onto top of unit until level.
Gently apply all items to be weighed onto the center of pan. Although
designed to be quite durable, avoid rough treatment as this may perma-
nently damage the internal sensor.
Warnings and Safety Information
Read all of the Operation Manual prior to attempting to operate your preci-
sion balance. Connect only Denver Instrument accessories and options, as
these are designed for optimal performance.
Warning!
Make sure that the voltage rating printed on the AC adapter
is identical to your local line voltage.
Do not use this balance in a hazardous location.
The only way to turn power completely off is by disconnecting the
AC adapter from the balance.
Protect the AC adapter from contact with liquids.
Warning!
This unit has no user serviceable parts! Do not open the balance housing,
as this will invalidate the manufacturer’s warranty!

Operation
AC Adapter Operation
CAUTION!
Use only a 9V Adapter with a negative tip, as provided, to supply AC
power. Use of another type of adapter may permanently damage the unit
and will void the warranty.
Insert the female plug into the receptacle at the rear of the unit, and then
into the desired electrical outlet. Check you use of any extension cord
which may affect power output. Unplug AC adapter when not in use for
extended periods.
Battery Operation
1. To install battery, open battery cover on bottom of balance and connect
battery to snap. Place battery into its compartment and replace the
cover. Always handle battery lead wires with care. DO NOT USE
EXCESSIVE FORCE!
2. Remove battery when balance is not used for extended periods.
Replace battery when LCD indicates “LO”.

Calibration
IMPORTANT: Only use the calibration weights provided or OIML
Class weights.
Always perform the calibration procedure AFTER the unit has been
allowed to properly warm up (at least 30 minutes). It is also recommend-
ed to recalibrate the unit periodically during long periods of use and to
always start a procedure by taring the unit to re-zero the balance.
Calibration is always recommended when first using the balance or after
the unit has been moved or subjected to an extreme change in tempera-
ture.
Calibration Procedure
1. After allowing unit to warm for 30 minutes, remove all items from the
pan and tare the balance.
2. After observing a stable “0” with an arrow in the (g) gram mode, press
and hold the CAL/MODE button until calibration weight value appears
on the display.
3. Gently place the correct calibration weight onto the pan.
4. The + sign will disappear. Wait approximately ten seconds as the unit
performs internal calibration.
IMPORTANT - Do not disturb the balance during this time. Avoid
vibration and air currents.
5. When calibration is complete the unit will beep, correct calibration
weight value will disappear for one second then reappear as an active
weight value. The balance is now calibrated.
6. Remove calibration weight and press the TARE button to reset the zero
point.
If calibration weight value remains on the LCD display, an improp-
er calibration weight has been used. Remove improper weight
and repeat calibration procedure with correct weight.

Display and Keypad Functions
• Power Up Segment Test: When first turning on the unit, all segments of
the LCD display will appear as shown. This display will remain for
approximately three seconds and then reset to zero.
• Stable Reading Indication: A right-facing arrow appears on the right side
of the display indicating the weighing mode in which the unit is operat-
ing. This arrow will disappear during weighing while the unit stabilizes,
and then reappear when a stable value is reached.
• Key Tone: Pressing the ON, TARE and CAL/MODE buttons on the front
panel will emit a tone indicating registry of the function. There is no key
tone with the OFF keypad.
• Overload: When an applied load exceeds the unit’s capacity, “H” will
appear on the display. Remove excessive load immediately.
• Negative Value: Any tared value will be displayed as a negative number
once all weight is removed from the weighing surface. The negative sign
will appear and tared value will be displayed.
• Tare: The tare feature is designed to allow the user to reset the balance
to zero at any time. Tare can also be used to eliminate the value of a pan
liner, scoop, beaker, etc. from a sample or procedure, when the weighed
material needs to be held in a container and only the net weight of the
material is desired.
Place the container only (without material) on the weighing tray, wait for
a stable reading and then press tare. The unit returns to zero and the
weight value of the container is permanently removed from the remain-
der of the procedure.
When all weight is removed from the weighing tray, the tared value of
the container will be displayed as a negative number. Press the TARE
key again to return the balance to zero.
NOTE: The total weight of the container plus material cannot
exceed the capacity of the balance.
• Auto Off: An auto shut off feature is provided which is opera-
tional only while the unit is operating under battery power. The
unit will automatically turn off after approximately two minutes if
no active weighing takes place. Auto shut off will not occur dur-
ing operation with AC Adapter.
• Lock Down Bracket: A molded piece is attached to the back of the bal-
ance housing that can be used on an optional basis to secure the unit. An
optional cable lock can be incorporated and is sold separately as an
accessory.

Keypad Functions
• ON/MEMORY: Press to turn on balance. For Memory function operation
refer to Memory Function, page 8.
•OFF: Press to turn off balance.
• CAL/MODE: Press and hold this key to begin calibration procedure as
outlined under the CALIBRATION section. After unit is on or calibrated,
briefly pressing the same key will change the weighing mode. When bal-
ance is turned on the unit initially defaults to the gram (g) mode.
However, if the mode is changed the balance will default to the last mode
used when turned on again.
The right facing arrow will point to the weighing mode the unit is cur-
rently displaying. To change modes briefly press the CAL/MODE key to
scroll between grams (g), ounces (oz), carats (ct), and penny weights
(dwt).
• TARE/PRINT: Press tare to reset the balance to zero. Tare can be used to
eliminate the weight value of a container from a sample or procedure.
The container weight is permanently removed from the remainder of the
procedure. When all weight is removed from the weighing tray, the tared
value of a container will be displayed as a negative number. Press TARE
again to return the balance to zero.
