To Remove the Battery Pack 1. Turn the two fasteners on the access  door counte
 r clockwise 1/4 turn, 
2. Grasp handle and pull the battery pack straight out. The battery will  auto
 matically disengage from its connectors.
The battery will operate for up to 100 hours (depending on LED brightness setting) 
before req
 uiring recharging. In order to c onserve battery life, the scale includes an 
automatic power off mode which senses oper ational status for no activity after 15, 30, 
45, or 60 minutes, and turns the scale off.  An additional battery saving feature is the 
automatic sleep mode. This f eature preserves battery life by dimming the display after 
5, 15, or 30 minutes of no scale activity. Charging time for a completely discharged 
battery is up to eight hours. A spare batte ry pack is recommended to keep the 
Challenger 3 in continuous operation.
NoteTo obtain maximum service life from your batteries they should be stored 
between -4°F and 122°F (-20°C and +50° C). Stored bat teries should be 
recharged every three months. Battery  is fully charged when the status 
indicator is flashing.

1.10 Battery Charger
1. Remove the battery from the scale.
2. Plug battery charger into an AC power r eceptacle. The input voltage is universal 
from
  115/230 VAC, 50/60 Hz. If the power input plug doesn’t match, contact 
MSI for information on international plugs.
3. Slide the battery charger connector plat e over 
 the top of the battery until the 
battery terminals mate with the charge r connectors, as seen through the two 
observation holes. 
4. Approximately six to eight hours is required to recharge a fully discharged  battery
 . If a battery was deep discharged, more time might be required, but the 
MSI-3460 prevents deep discharging. Partially discharged batteries will finish 
the charge faster.
The charger is a three stage float charger that  can be l
 eft on the battery indefinitely. It 
has a dual color LED to indicate the charging  state: RED- fast charge mode. GREEN- 
charged or float charge.

NoteTo obtain maximum service life fr om your batteries, the manufacturer 
suggests recharging after each 20 hours of use. Continuous deep 
discharging wi ll reduce maximum battery life cycle estimated at 2000 
cycles.
A second battery is recommended to  enable you to use your scal
 e 
continuously. Keep one on the charge r while the other is in service.

2.0 Operation
2.1 Power
To turn on the power.
1. Press 
POWER, the following will display in order:
• LED will light all segments at full brightness as a display test. 
• Display brightness will change to the setting determined in the display menu. 
• Software version number will display. 
• The  M
SI-3460  is ready for use.
2.2 Zero
Sets the zero reading of  the Scale. Use the ZERO key to take out small deviations in 
zero when the scale is unloaded. See “TAR E” for zeroing (Taring) package or pallet 
weights.
1. Press 
ZERO
NoteThe weight reading must be stable wi thin the motion window for the zero 
function to work.
The scale digits display 0 (or 0.0 or 0.00, etc). 
The backup memory in the MSI-3460 stores the zero reading, and can 
rest
 ore it even if the power fails. 
Rules for Use: • Works in GROSS mode or NET mode. Zeroing while in net mode will zero 
the gross  weight causing the display to show the negative tare value.
• The scale must be stable within th e 
 motion window. The scale will not zero 
if the motion detect annunciator is on. The scale will “remember” that it has 
a zero request for two seconds. If moti on clears in that time, the scale will 
zero.
• The scale will accept a zero setting ove r the full range of the scale (NTEP 
and 
 other Legal for Trade models may have a limited zero range). Zero 
settings above 4% of full scale will subtract from the overall capacity of the 
scale. For example if you zero out 100  lb. on a 1000 lb. scale the overall 
capacity of the scale will reduce to 900 lb. plus the allowed over-range 
amount. 
						

							Operation     13
2.3 Tare
Tare is typically used to zero out a known weight such as a packing container or pallet 
and display the load in NET weight. A  tare value is entered by pressing the TARE
key. The TARE function in the  MSI-3460 is defined as a Tare-In, Tare-Out operation. 
The first press of the  TA R E key stores the current weight as a tare value and then the 
scale subtracts the tare value from the gr oss weight and changes the display to NET 
mode. The next press of the  TARE  key will clear the tare va lue and revert the display 
to GROSS mode.
To view the gross weight without clearing the tare value, program the  USER key to 
th
 e function “NET/GROSS.” The RF remote  control has a Net/Gross permanently 
available.
To Tare and Display the Net Weight
1. Press 
TARE
NoteThe weight reading must be stable wi thin the motion window for the tare 
function to work.
The scale digits display 0 (or 0.0 or 0.00, etc) and the weight mode 
changes to NET
 . 
The backup memory in the 
MSI-3460 stores the tare reading and can 
restore it even if power fails.
To Clear the Tare and revert to Gross Weight
1. Press 
TARE. The net annunciator will turn off and the gross annunciator will 
turn on.
Tare - Rules for Use: • Only positive gross weight readings can be tared.
• The motion annunciator must be off. The weight reading must be stable.
• Setting or changing the tare has no effect on the Gross zero setting.
• Taring will reduce the apparent over range  of the scale. For example, taring a 
100
  lb container on a 1000 lb scale, the  scale will overload at a net weight of 
900 lb (1000-100) plus any additional allowed overload (usually ~4% or 9d).
• The scale stores the tare value in non-volatile memory and is restored when  power is 
 cycled.

3.0 User Defined Function Keys
The following function descriptions are for  optional user defined functions that are 
programmed on the front panel USER key or the two function keys (F1 & F2) on the 
RF remote control. The functions TO TAL, VIEW TOTAL, and NET/GROSS are 
available full time on the RF remote co ntrol. To enable any of the USER key 
functions, you must set up the USER keys following the procedures in  Section 4.0.
TEST
The TEST function provides an LED test that  li
 ghts all LEDs at once, next the SW 
Model number followed by the software version number, the battery voltage, and then 
performs a display test that counts from 00000 to 99999. Other internal tests are 
performed and if any test fails,  an error code will display. See Section 8.0 for a 
description of all error codes. Press the  USER key
  again within two seconds to enable 
a single step through all the test functions. In the single step mode, use the  USER key 
to scroll through the available test functions and the  TA R E key to start or display the 
individual tests. Use the  ZERO key to exit individual tests. Use the  ZERO key to exit 
entirely from the TEST function.
CH3.5n – Ch
 allenger 3 software version number: Press  TA R E to see the software 
version.
bAtt  – Battery volt
 age: Press TA R E to see the battery voltage.
d.tESt  – Di
splay test: Press  TARE to have the display count up from 00000 to 99999.
C-CAL  
– Cal constant display: Press  TA R E to view the C-CAL value.
TOTAL
NoteThe total mode must be programmed from the setup menus before the 
USER key will function.
For accumulation of multiple weighmen ts. The accumulator always uses the 
displayed weight, so GROSS and NET readings can be added into the same TOTAL. 
There are four modes of totalizing: manual  and three auto modes. 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.  This assures that a weight on the scale 
is only added to the total once. Both the  manual and three auto total modes require 
that the weight on the scale return belo w 0.5% (relative to full scale) of GROSS 
ZERO or NET ZERO before the next weighment can be added. Applied weight must 
be  ≥1% of full scale above GROSS ZERO or  NET ZERO before it can be totaled.
MANUAL TOTAL
The  US
ER  key under the MANUAL TOTAL mode functions in this manner:
Weight is > 1% of Capacity and has not been totaled – 
 Pressing the USER key 
will add the current weight to the TOTAL weight. The ACK LEDs blink to indicate 
the weight was accepted. The TOTAL annunciator lights and the total weight is 
displayed for five seconds and then the  number of samples is displayed for two 
seconds.
Current Weight has been totaled  – Pressing the
  USER  key will display the total 
weight for five seconds (View Total) without changing the total value. The TOTAL 
annunciator will light during the TOTAL weight display. After five seconds of total 
weight display, the number of samples is displayed for two seconds.

							User Defined Function Keys     15
AUTO TOTAL
The USER key under the AUTO TOTAL mode functions as Auto Total On / Auto 
To t a l  O ff .
The auto mode has three variations which are programmed in the SETUP menu: 
•AutoLoad – Any settled weight above the ‘Rise above’ threshold will be 
automatically totaled. Then the scale must fall below the ‘Drop below’ threshold 
before another total is allowed.
•AutoNorm – This mode takes the last settled weight to auto total with. The total 
occurs only once the scale goes below the threshold. This allows the load to be 
adjusted without a total occurring. Once the load is removed, the scale uses the 
last settled reading for total.
•AutoHigh – Similar to the AutoNorm mode except the scale uses the highest 
settled reading. Useful for loads that can’t be removed all at once.
View Total
The function key activates the total weight display followed by the number of 
samples. While the display is showing the total, total is cleared by pressing ZERO.
Net / Gross
Switches the display between net and gross modes. Net weight is defined as gross 
weight minus a tare weight. 
To switch between net mode and gross mode:
1. Press the USER key (Setup to the Net/Gross function).
2. The NET/GROSS key will only function if a tare value has been established.
3. Switching back to gross mode from net mode will not clear the tare value. This 
allows the operator to use the gross mode temporarily without having to re-
establish the tare value. Only clearing the tare or setting a new tare will change 
the tare value held before switching into gross mode.
OIML LFT units only: The NET/GROSS key is temporary action only. The gross 
weight is displayed for two seconds and then the display returns to the net mode. The 
only way to return to permanent gross readings is to clear the tare (see clear tare 
procedure).
PRINT
If print option is installed this menu choice will appear. The setup of the print function 
is covered in the option manual.
LEARN
Used for programming the RF remote control. This function is detailed in Section 6.0.
PEAK HOLD
Peak hold will only update the display when a higher peak weight reading is 
established. The peak hold function uses a high speed mode of the A/D converter 
allowing it to capture transient weights at a far higher rate than typical scales. Peak 
hold is cleared and re-enabled with the USER key. 
PEAK HOLD is not available on NTEP or OIML certified Legal for Trade  scales.
UNIT
The function key will switch the weight units between pounds and kilograms.
UNIT switching is not available on OIML certified Legal for Trade scales.
