INTRODUCTION
The Measurement Systems International Porta-Weigh Plus Crane Scale
represents a new level of technology and performance in the scale industry.
A 6 bit microcontroller coupled with an alphanumeric display gives unprec-
edented versatility and programmability. Advanced power saving circuitry
provides up to 300 hours of operation between charges with the standard sealed
lead acid (SLA) battery and up to 2000 hours of operating time from the
optional “D” cell alkaline batteries. The large, backlit alphanumeric display
provides precise, unambiguous indication of operating modes such as Net and
Gross. Digital calibration simplifies scale maintenance. The single circuit
board, fully shock-mounted and marine-proof construction makes for a rugged
and reliable overhead scale.

FEATURES
• Designed to meet or exceed all USA, Canadian, United Kingdom, and
International standards.
• Rugged construction throughout. Single printed circuit board is shock
mounted to withstand shocks in excess of 50 G’s. Switches are totally
sealed and rated for over 10 million operations.
• Precise high resolution 20 bit A/D conversion coupled with advanced 16 bit
microcontroller provides world class features and accuracy.
• Six 1.6 inch (40 mm) high digits for clear weight readings from a distance.
• Easy to read annunciation of measurement modes such as NET or GROSS
are provided on eight 0.8 inch (20 mm) alphanumeric characters. Also
used for menu prompts.
• Display illumination uses rugged, long life, light emmitting diode ( ED)
backlighting coupled with a transflective liquid crystal display providing
optimum display contrast under all ambient conditions from full sunlight to
total darkness. Operation is light-sensing automatic or manually set.
• Exceptional battery life: Typically 300 hours of continuous use between
charges provided by the 12V S A battery and 2000 hours of continuous use
is provided by the optional 8 alkaline “D” cell batteries. Maximum battery
life is reduced by use of the backlighting. The Porta-Weigh Plus will
automatically power down when not in use (this feature can be disabled). A
low battery indication appears when approximately 10% of battery life
remains.
• Easy to maintain: Full digital calibration assures reliable, repeatable measure-
ments.
• Complete marine sealing ensures reliable operations under harsh weather
conditions.
• Anti-EMI shielding is standard. ow emissions and susceptibility.
• Easily customized for special applications.
• IR Remote control is available as an option. Adds keyboard tare and other
features.

UNPACKING
When unpacking the scale from the shipping container, insure that all parts are
accounted for. Check the scale for any visible damage and immediately report
any damage to your shipper. It is advisable to use the original shipping con-
tainer when shipping or transporting the MSI- 300 Port-A-Weigh Plus.
BATTERY REMOVAL AND REPLACEMENT
1) Turn the MSI- 300 Off.
2) With one hand, hold the battery access door to prevent it from falling.
3) Rotate the two cam lock knobs on the access door counter-clockwise until
the door latches disengage.
) Carefully back the access door out of the battery well.
5) Relese the rubber retaining strap and remove the battery by pulling straight
back.
6) Install a fully charged battery by plugging it in to the exposed battery jacks.
The MSI- 300 will turn on briefly then turn itself off.
7) Reseat the access panel.
8) Turn the cam lock knobs clockwise until the access door is secured. Make
sure the door is firmly in place now, and before each use.
use.

The Battery Access Door and the Sealed ead Acid Battery are potential falling
hazards. When opening the battery access door, be sure to hold the battery to
prevent it from falling.
The Sealed ead Acid Battery contains lead and should be recycled when it has
reached the end of its life.
BATTERY LIFE
The MSI-4300 battery life depends on a number of factors: Brightness of the
liquid crystal display ( CD) and number of segments lit, the use of the light
emitting diode ( ED) backlighting, and the age and condition of the sealed lead
acid battery (S A) . The MSI-4300 will automatically turn the scale off when
the S A battery drops to approximately 10.5V. You must recharge the battery
when this happens. S A batteries do not suffer from memory effects and
actually benefit from frequent rechargings. Recharge the battery whenever it is
convenient even when it still has available life. Due to the small maintenance
discharge imposed on the battery by the MSI-4300 electronics, do not store the
MSI-4300 with the battery inside the scale for extended periods (longer than
7-10 days). Remove the battery from the scale.
attery Use Guidelines
1) Recharge whenever convenient. Do not wait for the scale to shut itself off if
your work situation permits.
2) If you need the scale in continuous operation, keep a fully charged spare
battery at hand. Replace the drained battery as close as possible to the low
battery warning, or earlier.
3) S A Batteries that have not been deep discharged should withstand 500 to
1500 charging cycles.
4) The low battery warning will indicate about 2-4 hours of additional use
before the MSI-4300 turns itself off.
5) If the MSI-4300 is not going to used again soon, remove the S A battery to
prevent deep discharge while the unit is in storage.
BATTERY CHARGER
Each MSI-4300 is shipped with a battery charger designed to charge and
maintain the battery. Exact charging time will depend on the degree of dis-
charge of the battery. A battery removed when the low battery warning first
appears should take about 4 hours to fully charge.

Using the Charger
1) Remove the Battery from the MSI-4300. See previous page for removal
instructions.
2) Connect the charger assembly to the AC supply (86-260VAC). The Power
Status light should be green. If the power status light fails to illuminate,
check your AC power connection and make sure the Vin jack is fully seated.
AC power cords suitable for any world location are available from MSI.
3) Plug in the polarized connector to the jacks on the battery.
4) The Charge Status light should turn ORANGE indicating fast charge. If the
status light remains Green when the battery is first plugged in, the battery
may be defective.
5) Charge until the status light turns GREEN.
When the charge cycle is complete you can (and should) leave the battery on
the charger until it is needed. The charger keeps a maintenance float charge on
the battery to ensure the best possible operation times. For scales that are in
high usage, MSI recommends obtaining a spare battery so one can always be on
the charger.
BATTERIES
Optional Alkaline attery Power
8 Standard “D” cells. Alkaline type is preferred, but standard Carbon-Zinc can
also be used. This reduces the available battery life in half. Also Ni-Cad “D”
cells work fine. Ni-Cad battery life varies widely, but should be about one
quarter the equivalent of Alkaline.
Installing/Changing
1) The batteries must have enough charge to ensure accurate operation. If
the batteries are too low, the scale will automatically shut off (8 batteries
in series must total more than 5.4V).
2) Turn the MSI-4300 Porta-Weigh Plus off.
3) Remove the battery tubes by turning the knobs counterclockwise. It is
not necessary to remove both tubes at once.
4) Replace the batteries with four fresh “D” cells in each tube with correct
polarity.
5) Reinstall the battery tubes by inserting the tubes back into the unit and
turning the knobs clockwise.
Note: The batteries can be checked with the Test Mode. Power displayed is in
relative percent (%) of battery life (applies to alkaline batteres only). If the
number with fresh batteries is extremely low (less than 10%), turn off the
power, remove the tubes and check that the polarity of all batteries are correct.

ZERO NET/GROSS TAREPOWER TEST
IN / OUT
1 2 3 4 5
1) POWER
Push to turn the scale on or off.
2) ZERO
Used to zero the scale. Zero range depends on standard.
3) NET/GROSS
When in NET mode, pushing this provides a temporary (4 seconds)
gross weight reading.
4) TARE IN/OUT
When in GROSS mode, pushing TARE will zero any weight on the scale
which causes the scale to go into the NET mode. When in NET mode,
pushing TARE will clear the TARE value and the scale will revert to the
GROSS mode.
5) TEST
When pushed, this causes a display segment check, and provides battery
and RCA tests.
Keyboard Features
• Silicon elastomeric rubber switches provide up to 10 million operations.
Far more rugged than mechanical switches that can withstand excessive
impact without affecting operation.
• Rubber membrane provides watertight and salt spray-proof seal. Addi-
tional poly shield on underlay provides second layer of integrity and
prevents humidity contamination.
