INTRODUCTION

The Measurement Systems International Porta-Weigh Plus Crane Scale
represents a new level of technology and performance in the scale industry.
A16 bit microcontroller coupled with an alphanumeric display gives unprec­edented versatility and programmability. Advanced power saving circuitry
provides in excess of 2000 hours of operating time from ordinary “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 shock­mounted and marine-proof construction makes for a rugged and reliable
overhead scale.

50,000 kg unit is 450% of rated capacity

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 1.65 inch high (42 mm) digits for clear weight readings from a distance.

• Easy to read annunciation of measurement modes such as NET or GROSS
are provided on eight .825 inch (20.9 mm) alphanumeric characters. Also
used for menu prompts.

• Display illumination uses rugged, long life, electroluminescent 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 2000 hours of continuous use provided by
8 alkaline “D” cell batteries. Maximum battery life is reduced by use of the
backlighting; full time low light operation will provide up to 300 hours of
operation. A typical operating cycle of 8 hours daylight use and 2 hours night
use will provide 10 months of operation on a single battery change. 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 measure­ments.

• Complete marine sealing ensures reliable operations under harsh weather
conditions.

• Anti-EMI shielding is standard. Low 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 con­tainer when shipping or transporting the Port-A-Weigh.

BATTERIES

Type

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 5.4 V).

2) Turn the 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.

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. 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 the batteries is correct.

KEYBOARD OPERATIONS

T

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 RCAL 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. Addi­tional poly shield on underlay provides second layer of integrity and
prevents humidity contamination.
