BATTERY PACK
The Port-A-Weigh is powered by a 12 volt rechargeable battery. The battery is located in the
rear compartment of the scale. Two stainless steel fasteners secure the battery access door. To
remove the battery for charging; unlatch the fasteners and pull the battery straight out. The
battery will automatically disengage from its connectors and may be plugged into the battery
charger for recharging.
BATTERY OPERATION
BATTERY LIFE
The battery will operate continuously for 100 hours with the LED display before requiring
recharging. The Port-A-Weigh will alert you when the battery is within 2 hours of requiring
recharging by illuminating the “BT” (Low Battery) annunciator.
When the battery requires recharging, the weight reading on the display will be replaced by
“LO”, after which the scale will shut itself off to prevent battery damage. If the On button is
depressed at this point, “LO” will reappear and then the scale will again deactivate automatically.
Instructions for charging are located on the battery charger. Charging time for a completely
discharged battery is approximately 16 hours. A spare battery pack is recommended to keep
the Port-A-Weigh continuously operational.
Note: More frequent charging of the battery prolongs its life.
The MSI-4260 battery life depends on a number of factors: Brightness of the LED display,
the number of segments lit, and the age and condition of the SLA (sealed lead acid) battery.
The MSI-4260 will automatically turn the scale off when the SLA battery drops to approximately 10.5V. You must recharge the battery when this happens. Leaving a discharged
battery in the scale, which has a maintenance battery drain, can result in a deep discharge
battery which will shorten its service life.
SLA batteries do not suffer from memory effects and actually benefi t from frequent recharg-
ings. Recharge the battery whenever it is convinent even when it still has available life. Due
MSI-4260 Port-A-Weigh • User Guide Page 7
Page 8
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L
to the maintenance discharge imposed on the battery by the MSI-4260 electronics, do not
store the MSI-4260 away with the battery inside. Remove the battery if the MSI-4260 will
not be used for more than 2 weeks.
Battery 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 continuously, keep a fully charged spare battery at hand. Replace the
drained battery as close as possible to the low battery warning or earlier.
3) SLA 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 MSI4260 turns itself off.
5) If the MSI-4260 is not going to be used again soon, remove the SLA battery to prevent
deep discharge while the unit is in storage.
6) Recycle the battery to an authorized recycling center when average life drops to 20 hours
or less.
BATTERY CHARGER
Each Port-A-Weigh is shipped with a battery charger designed to charge and maintain the
battery. Exact charging time will depend on the degree of discharge of the battery. A battery removed when the low battery warning fi rst appears should take about 4 hours to fully
charge.
When the battery is new, it may take signifi cantly longer for the initial charge. MSI recom-
mends charging a new battery for 24 hours. It might take several charge/discharge cycles
before full capacity is reached. Deep discharge batteries will also take signifi cantly longer to
charge.
Using the Charger
1) Remove the battery from the MSI-4260. 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 fi rst 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 fl oat 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.

RESET THE SERVICE COUNTER WARNING
1) After inspecting the load train, remove the calibration seal screw.
2) Push the Calibration button using a blunt screwdriver.
3) Push [ZERO] to return to normal operation.
Note: This procedure does not reset the service counter.
TOTAL (totAL)
Function
For accumulation of multiple weighments. The accumulator always uses the displayed
weight, so GROSS and NET readings can be added into the same TOTAL. There are two
Modes of totalizing: Manual and Auto. The Manual Mode requires the TOTAL button be
pressed with the weight on the scale. The weight will be added to the previously accumulated
value. The Auto Mode will automatically add the last settled and stable value to the TOTAL.
Both Modes require that the weight on the scale return within 1% (relative to full scale) of
GROSS ZERO or NET ZERO before the next weighment can be added. This assures that a
weight on the scale is only added to the total once. Applied weight must be 2% of full scale
above GROSS ZERO or NET ZERO before it can be totaled.
MANUAL TOTAL
Function
Allows for accumulating weight manually by pressing a button.
Use
1) The Motion indicator must be off, the scale must be stable ±1 division. If there is considerable motion on the scale, use the Medium or High Filter setting (see Filter Setup).
The scale will accept the TOTAL button when in motion, but will not TOTAL until the
Motion indicator is off.
2) Only positive readings can be accumulated.
3) After a weight is totaled, the weight on the scale must return below 1% of full scale
capacity relative to GROSS ZERO or NET ZERO before another weight can be added to
the TOTAL. This assures that a weight on the scale is only added to the scale once.
4) Press
5) If the Motion indicator is on, the TOTAL indicator will begin blinking, and continue

CALIBRATION SETUP
Function
Calibration Setup is used to initiate calibration or to set seldom changed factory settings.
There are two types of calibration:
1) Initial Calibration;
2) Subsequent Calibration
Calibration must be accomplished by a qualifi ed scale technician trained in Certifi ed Calibra-
tion Standards. To initiate calibration of a Port-A-Weigh, the technician is required to have an
accurate test weight system of adequate capacity and, in the case of a Legal For Trade PortA-Weigh, the test weight system must be certifi ed by the appropriate regulatory agency.
Important Note: At any point (except when entering calibration weight values), the calibration procedure can be halted by turning POWER off.

CALIBRATION (CAL)
Function
Used to Calibrate the scale load cell. There are two types of calibration:
1) Initial Calibration and
2) Subsequent Calibration
INITIAL CALIBRATION
Function
Initial Calibration is used at the factory when Calibrating for the fi rst time, when the circuit
boards have been replaced or after the scale has gone through System Initialize.
Note: Do not use this procedure for routine Calibration.
Action
1) Turn on the scale by pressing the [POWER] button.
2) Press Cal button once. "CAL" will appear, then press [ENTER/TARE]. The following steps
will occur:
3) Units selection: Display fl ashes “Unit” with the lb indicator. If calibrating in lb, press
[ENTER/TARE], or to select kg, press [SELECT/F1], then [ENTER/TARE]. This step only effects
what the test weight unit is, it does not prevent lb/kg switching.
Note: This step will not occur in scales setup by the Standards menu to measure in only one
unit.
4) Display shows “CAP” for 2 seconds then fl ashes “0”. Input the capacity using [SELECT/F1]
and [ENTER/TARE]. After each digit is entered another digit is brought up by pushing F1.
For 100,000 lb capacity, since there are only have 5 digits, the correct procedure is to
enter the capacity as 99980, assuming a 20 lb ‘d’, or 99950 with a 50 lb ‘d’. 20 lb. is
the highest MSI recommended resolution for the 100k Load Cell. The scale will reach
a few ‘d’ over 100,000 lb using the X1000 annunciator, however it cannot be calibrated
at 100,000 lb since there are only 5 digits in the display. It is recommended that 100,000
lb systems be set to a “count by” not less than 20 lb, preferribly at a “count by” of 50 lb.
A 50 lb ‘d’ will settle faster and will display with more stability, though this depends on
the application. With a 20 lb ‘d’, the scale will display overload at about 100140 which
will display as 100.14 X1000. With a 50 lb ‘d’, the scale will display overload at 100400
which will display as 100.40 X1000. This assumes capacity was set at 99980 or 99950.
5) Display shows “d” for 2 seconds, then fl ashes the default Count By (division). Press
[ENTER/TARE] to accept, or press [SELECT/F1] to pick another Count By, then press [ENTER/
TARE]
.

5) Display fl ashes “GAin4”. Press [ENTER/TARE] to accept, or press [SELECT/F1] to pick an-
other gain, then press [ENTER/TARE]. See Gain Table.
Capacity of Scale Gain Capacity of Scale Gain
500 lb 250 kg 4 30,000 lb 15,000 kg 3
2,000 lb 1,000 kg 3 50,000 lb 25,000 kg 3
5,000 lb 2,500 kg 4 70,000 lb 35,000 kg 3
10,000 lb 5,000 kg 4 100,000 lb 50,000 kg 3
20,000 lb 10,000 kg 4
Gain Table
For example, a 100,000 lb load cell needs a gain of 3. Press [SELECT/F1] until GAin3
appears, then press [ENTER/TARE].
6) Display fl ashes “UnLd”. Unload the scale, wait for the Scale to stabilize (not swinging or
vibrating) and press [ENTER/TARE]. The scale will display “CALC”, for calculating.
7) Display shows “LOAd” for 2 seconds then fl ashes the capacity. Load the scale with a test
weight that is equal to capacity weight; or if the test weight is less than capacity, load the
scale fi rst and then enter the actual weight of the test weight by pressing [SELECT/F1] then
[ENTER/TARE]. Make sure the scale is stable before entering the last number. After the last
number of the weight has been entered and the motion indicator is off press [ENTER/TARE].
If the motion indicator never goes off, stabilize the scale and weight as much as possible
before pressing [ENTER/TARE]. The display will show “CAL’d” if successful, or “CErr” if
not successful. An unsuccessful calibration can be due to an improper gain setting, or use
of a calibration weight that is too light.
A common error is entering the calibration weight value before the scale is loaded. The
weight must be on the scale and stable before the ENTER key is pressed or a cal weight
value is entered. On large scales like this 100k in question, it is rare that capacity weights
are available. However, during the initial calibration of this scale, you will have to use a
real weight. Until the scale has been calibrated once, you cannot use R-Cal techniques.
Recommend a test weight of at least 20,000 lb. However you can probably get by at
10,000 lb. For example, to enter a 20,000 lb load as the calibration weight, the procedure
is:
a) [/F1] “1”
b) [/F1] “2”
c) [ENTER/TARE] display reads “2”
d) [/F1] display reads “20”
e) [ENTER/TARE]
f) [/F1] “0” display reads “200”
g) [ENTER/TARE]
h) [/F1] “0” display reads “2000”
i) [ENTER/TARE]
j) [/F1] “0” , display reads “20000
k) [ENTER/TARE] fi nishes the test weight entry.
Of course, at any time you can use the [/F1] key to enter any number using the same
procedure. Not that it’s applicable here, but to enter less than fi ve digits, just press [ENTER/
TARE]
moves on to the next step. Again, make sure the test weight was loaded and the scale is
stable before entering the last digit.

scale will display "CALC" (for calculating).
4) To input the Calibration weight value the display will show "LOAd" for 2 seconds then
fl ash the capacity. Load the scale with this weight or input another weight. After the last
number of the weight has been entered and the motion indicator is off, press [ENTER/TARE].
The display will show "CAL’d" if successful, or "CErr" if not successful. An unsuccessful calibration can be due to an improper gain setting, or use of a calibration weight that
is too light.
5) To set the CAL-r value the display fl ashes "UnLd". Unload the scale and press the
[ENTER/TARE] button. Afterwards "CAL-r" will be displayed until the value is determined.
If successful, then the CAL-r value is displayed for 10 seconds or until any button is
pressed. If unsuccessful, the display will show "r-Err" for 2 seconds.
Note: It may be desirable to bypass a calibration step. To do so press [CLEAR/ZERO]. The step
bypassed will retain the default or last set value. However, bypassing a calibration step
may result in an incomplete or inaccurate calibration.

Description
MSI-4260 crane scale can be equipped with a RF Remote Control
(RFRC). The RFRC is a transmit only device that can be used to perform basic scale functions. Range will vary from 25’ to 100’ depending
on room conditions and line of sight to the display. The remote receiving
antenna is behind the red lens of the crane scale and best range will occur when the display is visible to the operator using the RFRC. One big
advantage the RFRC provides is the ability to turn the unit on remotely.
The RFRC is available in three versions differing only in transmit frequency. The standard version operates at 418MHz. Available alternative
frequencies are 315 MHz and 433 MHz.
Functions
The RF Remote control (RFRC) duplicates the function of the front panel keys on MSI-4260
crane scales. The POWER, ZERO, NET/GROSS, and TARE key function identically.
Note: F2, Total (F3) and View Total (F4) on the RFRC are not supported by the Port-A-
Weigh. Total and Viewing the Total can be initiated with the F1 key on the RFRC.
The F1 key functions the same as the User Programmable Function (F1) key on the front
panel. The exact function of the key depends on the F1 key setup procedure. See page 11 for
the procedure to confi gure the F1 key, which will also confi gure the F1 key on the remote.

Setting the Transmitter Address
In order to allow the formation of up
to 1024 unique Transmitter-Receiver
relationships, the transmitter’s address may be selected using internal
DIP switches as shown. The switches
are accessed by removing the DIPswitch access cover.
Note: If the switch is on, the address
line is connected to ground,
otherwise it is fl oating. The
receiver’s address must match
in order for the units to communicate.
MSI supplies the transmitter and receiver as a matched set with the DIP switches already
confi gured. A replacement RFRC will only need to have the transmitter DIP switches set. To
change the DIP switch in the receiver requires disassembly of the crane scale front casting.
Note: Due to different DIP switch styles, the receiver DIP switch appears opposite to that of
the transmitter. On the receiver, the OFF position is on the right, and the ON position
is on the left.
Contension Considerations
It is important to understand that only one transmitter at a time can be
activated within a reception area. While the transmitted signal consists
of encoded digital data, only one carrier of any frequency can occupy
airspace without contention at any given time.
Battery Replacement
The remote unit utilizes a CR-2032 Button Lithium Cell. In normal use
it will provide 1-2 years of operation. Access for replacement is accomplished by removing the battery access cover by pressing down fi rmly on
the label area and sliding it off. Once the unit is open, remove the battery
by sliding it from beneath the holder. Replace the cell with the same type
while observing the polarity shown.
