1.2General Information
1.2.1User Guide & MSI-3460 Conventions
1. Keys used in operations are printed in BLUE and capitalized.
2. Screen shots that are used in menus are displayed in RED and shown in a 7-
segment font. Not all characters can be displayed with this font, but a close
approximation is shown.
3. If a function key does not work, it is probably because the MSI-3460 is not setup
to support the key. For example, if the User key is set for TOTAL, you must also
set up the TOTAL mode in the Setup Menu.
4. When in Setup menus, the ZERO key drops back one menu level. At the root
menu level, the ZERO key stores the changes and returns to the weight mode.
5. When in Setup menus, the POWER key returns you directly to the weight
display without storing the changes.
6. When in Setup menus, the USER key functions as the scroll key.
7. When in Setup menus, the TARE key functions as the ENTER/SELECT key.

automatic power off mode which senses operational 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 feature 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 battery pack is recommended to keep the
Challenger 3 in continuous operation.
To obtain maximum service life from your batteries they should be stored
between -4°F and 122°F (-20°C and +50°C). Stored batteries should be
recharged every three months. Battery is fully charged when the status

Rules for Use:
ZERO
The weight reading must be stable within 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.
• 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 the
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 motion clears in that time, the scale will
zero.
• The scale will accept a zero setting over 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.

2.3 Tare
TARE
Note
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 TARE key stores the current weight as a tare value and then the
scale subtracts the tare value from the gross weight and changes the display to NET
mode. The next press of theTARE key will clear the tare value and revert the display
to GROSS mode.
To view the gross weight without clearing the tare value, program the USER key to

3.0User Defined Function Keys
Note
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 TOTAL, VIEW TOTAL, and NET/GROSS are
available full time on the RF remote control. To enable any of the USER key
functions, you must set up the USER keys following the procedures in Section 4.0.

The TEST function provides an LED test that li
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
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 TARE key to start or display the

TOTAL
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 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 below 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.

AUTO TOTAL
The USER key under the AUTO TOTAL mode functions as Auto Total On / Auto
Total Off .
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 reestablish 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.
