MSI-4260 Port-A-Weigh •User Guide Page 7
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
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 automati-
cally.
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.
BATTERY 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 ap-
proximately 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 benefit from frequent recharg-
ings. Recharge the battery whenever it is convinent even when it still has available life. Due

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
Page 8 MSI-4260 Port-A-Weigh •User Guide
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 MSI-
4260 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 bat-
tery removed when the low battery warning first appears should take about 4 hours to fully
charge.
When the battery is new, it may take significantly 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 significantly 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 con-
nection 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.

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
MSI-4260 Port-A-Weigh •User Guide Page 9
The charger is a universal input type and is rated for 100-240VAC, 50-60Hz. AC power
cords suitible for any world location are available from MSI.
BATTERY REMOVAL AND REPLACEMENT
1) Turn the MSI-4260 off.
2) With one hand, hold the battery access cover.
3) Release the two latches holding the access cover.
4) Carefully lower the cover and when possible, hold the battery in place. The battery might

GROSS).
ZERO
Function
Sets scale to ZERO.
Use
1) The scale must be stable. The scale will not ZERO if the motion detect indicator is on.
2) The scale must be in the GROSS Mode. The scale will not ZERO in NET Mode.
3) The scale will accept a ZERO setting over the full range of the scale (Legal For Trade
models might have a limited ZERO range). ZERO settings greater than 5% of capacity
will subtract from the overall capacity of the scale.
Action
1) Press [ZERO]. The weight reading must be stable within ±1 division. If this condition is
met, the digits display "0" (or "0.0" or "0.00", depending on resolution).
2) The ZERO setting is stored in backup memory, and the setting will be restored the next
time the scale is turned on.
Final
Digits display "0" (or "0.0" or "0.00", depending on resolution).
TARE
Function

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
MSI-4260 Port-A-Weigh •User Guide Page 13
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 con-
siderable 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
[F1] (Function button must be programmed as TOTAL (see Scale Setup).
5) If the Motion indicator is on, the TOTAL indicator will begin blinking, and continue
blinking, until motion stops and the Motion indicator turns off. The current weight is
added to the TOTAL register and the TOTAL weight is displayed.
6) The TOTAL indicator (center right of display) will also illuminate for 4 seconds provid-
ing reinforcement that the TOTAL command was accepted.
Final
After totaling, normal weighing resumes.
AUTO TOTAL
Function
Allows for Auto accumulate.

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
Page 14 MSI-4260 Port-A-Weigh •User Guide
Use
1) When a weight threshold of 2% of Full Scale (FS) above NET ZERO or GROSS ZERO
is exceeded, the accumulate function operates automatically.
2) When a weight that meets the minimum acceptable limit settles (no Motion), the TOTAL
indicator will flash 3 times.
3) If the weight changes to a new settled value the TOTAL indicator will flash again indicat-
ing the previous settled reading has been replaced.
4) When a weight is totaled, the TOTAL indicator will flash for a steady 4 seconds, indicat-
ing the weight has been totaled and the TOTAL value will be displayed.
5) The displayed weight is added to the accumulated value in the TOTAL Register only
when the weight returns to ZERO (±1% of Full Scale ).
6) The last settled reading is what will be used for totalizing when the scale returns to
ZERO.
WARNING: The operator must take caution that, when removing the load, the scale does
not go out of Motion; or an erroneous reading could occur. The last settled weight is actually
added to the TOTAL when the scale returns to less than 1% of full Scale capacity.
Action
1) The scale cannot be in motion. An Auto TOTAL acceptable reading is indicated by 3 or
more short flashes of the TOTAL indicator.
2) Weight readings must be greater than 2% of full scale, relative to NET ZERO or GROSS
ZERO.
3) Each reading added to TOTAL must be preceded by a return to ZERO (NET or GROSS)
±1% of full scale. Totalization of the last settled weight is indicated by a 4 second flash of
the TOTAL indicator, and a display of the current TOTAL.
Final
After totaling, normal weighing resumes.
TO CLEAR THE LAST TOTALLED WEIGHT
Function
If the last totaled (automatic or manual) weighment was a mistake, it can be erased with the
following procedure. This erases only the last totaled value.
Action
1) Press [F1], then [ENTER/TARE]. The display will read the revised TOTAL for 2 seconds.
(This procedure assumes that you have not modified the F1 function.)
Final
After displaying the update TOTAL, normal weighing resumes.

AUTOMATIC POWER OFF (A-OFF)
Function
The A-OFF feature, when enabled, prolongs the battery life of the scale by turning POWER
off when the scale is not in use. Any time a button is depressed (any button), or the detected
weight is in Motion, the time limit is reset. Therefore, the scale will stay on indefinitely if the
weight is changing or any button is pressed at least once. With A-OFF disabled, the scale will
remain on; only pressing POWER will turn it off.
Action
To Change the A-OFF Mode:
1) Hold in the [F1] button while turning on the power.
2) Press [SELECT/F1] until the display reads "A-OFF".

[SELECT/F1] to scroll to a different USER Setup operation.
FILTER (Filtr)
Function
Allows three levels of filtering to stabilize readability of the weight display.
Use
1) Use LO (low setting), for most scale applications. It settles fastest and is intended for
general use.
2) Use HI-1 (medium setting), when the scale is being used under conditions that cause light
to medium swinging.
3) Use HI-2 (high setting), when there is significant scale motion. There is a time penalty
when using the HI-2 setting. The operator should wait at least 5-15 seconds to ensure
that the final reading has settled (motion indicator off). (Not available in some Legal For
Trade scales).
Action
To change the Filter settings:
1) Hold in the [F1] button while turning on the power.
2) Press [SELECT/F1] until the message reads "Filtr".
3) Press [ENTER/TARE]. The currently selected filter will flash.
4) Press [SELECT/F1] to change from LO (low), HI-1(medium) or HI-2 (high) settings. When
the desired Filter setting is displayed on the message display, pressor [ENTER/TARE] press
[CLEAR/ZERO] to exit without changing the setting.
