Installation
– It is recommended to connect
Denver accessories and options,
as these are optimally designed
for use with your balance/scale.
– Do not open the balance/scale
housing as this will void the
manufacturer’s warranty.
Warnings and Safety Precautions
Safety Information
lTo prevent damage to the equip-
ment, please read these operating
instructions carefully before using
your balance/scale.
!Do not use this equipment in
hazardous areas.
!Make sure the voltage rating print-
ed on the power supply is identical
to your local line voltage.
!Use only commercially available
9V batteries (not included).
If desired, you can use a recharge-
able battery.
– The balance/scale is energized at
all times unless you disconnect the
AC adapter and, if connected,
the battery.
– Protect the AC adapter from con-
tact with liquid
!Exposure to excessive electromag-
netic interference can cause the
readout value to change. Once the
disturbance has ceased, the instru-
ment can be used again in accor-
dance with its intended purpose.

Getting Started
Equipment Supplied
– Balance/scale
– Weighing pan
– Plug-in AC adapter
Additional equipment with models
MXX-612, MXX-412, MXX-212,
MXX-601:
– Calibration weight
Additional equipment with model
MXX-123:
– Calibration weight
– Round glass draft shield
– Level indicator and adjustable feet
Installation
Choose a location that is not subject
to the following negative influences:
– Heat (heater or direct sunlight)
– Drafts from open windows and
doors
– Extreme vibrations during
weighing
– Excessive moisture
Setting Up the Balance/Scale
lPlace the components on the
balance/scale in the following
order:
– Reversible round weighing pan
– Round glass draft shield on model
MXX-123

6
Connecting the Balance/Scale
to AC Power
!Use only the AC adapter for
optimal performance and safety.
§Insert plug into the jack
(located on back of balance/scale)
§Plug the AC adapter into an electri-
cal outlet
!LISTED power supply 11 V–21 V
compliant with NEC Class 2 output.
Below-Balance/Under-Scale Weighing
A port for a below-balance weighing
hanger is located on the bottom of
the balance/scale.
§Open the cover plate on the
bottom of the balance/scale.
§Attach the sample (e.g., using
a suspension wire) to the hanger.
$Install a shield for protection
against drafts if necessary.
Installing the Battery
(not for model MXX-123)
$Batteries are not included with the
equipment supplied
!Use only commercially available
9V batteries.
!If you use a rechargeable battery,
recharge it with an external battery
charger.
§Lay the balance/scale on its side
§Open the battery compartment:
remove the compartment cover
§Install the battery in the compart-
ment
$Make sure the polarity is correct.
!Close the battery compartment:
slide the cover into position until it
snaps into place
!Do not throw away used batteries
with normal household waste.
Rechargeable batteries contain
toxic materials and must be dis-
posed of in accordance with local
waste disposal regulations.

Leveling the Balance/Scale
(only for model MXX-123)
§Always level the balance/scale
again any time after it has been
moved to a different location.
Example: moving bubble from
R to L
§Turn the feet as shown in the
diagram until the air bubble is cen-
tered within the circle of the level
indicator.
> In most cases this will require
several adjustment steps.
Removing Weights for
Calibration/Span Adjustment
(only for models MXX-612, MXX-412,
MXX-212, MXX-601, MXX-123)
§Grasp the tab to turn and pull out
the weight compartment.
$Follow instructions on page 15 for
calibration/span adjustment.
Warmup Time for Model MXX-123:
To ensure accurate results, the scale
must warm up for 1 hour before
operation. Only after this time will
the scale have reached the required
operating temperature.

Operation
Basic Weighing Function
Features
– Zeroing the balance/scale
You can zero the balance/scale within
the entire weighing range, up to the
maximum capacity.
Preparation
§Switch on the balance/scale:
press the (ON/OFF) key
§If necessary, zero the balance/
scale: press the (ZERO) key
$If necessary, change the configura-
tion settings: see the chapter
entitled “Configuration”
$If desired, load the factory settings:
see the chapter entitled
“Configuration,” menu item 9.– 1
Additional functions:
$Switching off the balance/scale:
press the (ON/OFF) key
$Battery operation: automatic shut-off
after 2, 5 or 10 minutes; see chapter
on configuration. Example: 2 min-
utes. If the weight readout remains
unchanged and no keys are pressed
for at least two minutes, the battery
symbol “ “ starts flashing.
After another 2 seconds, the
balance/scale shuts off automati-
cally, unless a key is pressed.
Description of the Keys
(ON/OFF) On/off key: switches the
balance/scale on and off or
switches it to the standby
mode.
Battery operation: on;
turns backlight on; off
(ZERO) Zeros the balance/scale;
press and hold 2 seconds:
opens the application menu
(CAL) Starts calibration/adjust-
ment
(F) Starts an application pro-
gram; scrolling in applica-
tion menu, configuration
menu and calibration menu
(ENTER) Confirms the selected
setting; exits application,
configuration & calibration
menu if key is pressed
and held for at least
2 seconds.
(PRINT) Generates a printout or
data output
Example: Determine weight of sample
Step Key (or instruction) Display
1. Switch on the balance/scale (ON/OFF)
Self-test runs
Display: Software version r 31.01 g
2. Place container on the balance/scale 52.0 g
(in this example, 52 g)
3. Zero the balance/scale (ZERO) 0.0 g
