M2000 INDICATORS
Utilizing over 25 years of research and development in electronic weighing
systems, Western’s M2000 high performance scale indicators are the industry
standard for speed, versatility, and reliability.
M2000 weighing systems can be custom-tailored to meet the needs of any
application and are ideal for new installations as well as upgrades to existing
systems. The M2000 Indicator performs equally well on heavy industrial (Truck)
scales and small capacity (packaging) scales. For a complete synopsis of
M2000 Indicator functions and other custom weighing services, please visit
www.westernscale.com or contact the Western Scale Co. Ltd. factory.
The M2000 Indicator family includes:
•M2000 A – 3 Channel Analog Indicator (2 COM Ports). One of the
world’s best and most affordable high speed, fully featured indicators.
For use with Analog loadcells.
•M2000 A-S – Single Channel Indicator (1 COM Port). M2000 features
and quality at a low cost. For use with Analog loadcells.
•M2000 D - 3 Channel Digital Indicator (2 COM Ports). Digital
Communication with your scale for maximum lightning protection and
data integrity. Converts Analog loadcell signals to digital data at the
scale via the DLC Smart Box.
This technical manual contains specific information regarding:
•M2000 System Installations
•Scale Set-up
•Scale Calibration
•Enabling and Disabling M2000 functions

M2000 USER INTERFACE (DISPLAY & KEYPAD)
M2000 Displays are split into two components: The Alpha-Numeric Weight
Display and the LED indicators.
ALPHA-NUMERIC DISPLAY
•The Alpha-Numeric Weight Display has 6multi-character LED’s. Scale
weights, Error messages, and Calibration information are shown here.
•A negative weight is shown by a (-) minus sign on the far left LED
character.
•The number of decimal points on the display is determined in Calibration
Mode. (See Scale Set-Up Parameters - Page 30)
•On power-up, a scrolling “[]2000” will be displayed, followed by the
software version number. The scale weight will then be displayed.
LED INDICATOR LAMPS
•These triangular LED’s will illuminate to indicate certain scale conditions.

KEYPAD & KEY FUNCTIONS
ON / OFF KEY
Powers-up the M2000. The key must be pressed and held for 1
second to turn the M2000 off.
ZERO SCALE KEY
Removes small, residual weight values to return the displayed weight
to zero. The Centre Zero LED will be illuminated.
If the [ZERO SCALE] button is pressed in NET weighing mode, the
stored tare weight will appear as a negative weight on the display.
The scale cannot be zeroed if:
•The [ZERO] key has been disabled.
•The scale is in MOTION.
•The residual weight on the scale is too great (More than 2%
of Scale Capacity. See Push to Zero Window – Page 40)
Three rapid beeps will sound to indicate any of these conditions!
CLEAR KEY
Press the [CLEAR] key to erase previously entered tare values. The
[CLEAR] key will also function to cancel any keypad entry.
NUMERIC
KEYS
The [ON/OFF] key is not hard wired to the M2000 power supply. A
Power Bypass function is available for Process Control and other
applications. (See Power Switch Bypass - Page 47)

TECHNICAL MANUAL
TARE KEY
There are 2 methods used to tare the scale:
Method 1: Tare a random weight on the scale.
•Place an item of unknown weight on the scale. (Container, Box, etc.)
•Press the [TARE] key and the displayed weight will be tared. Note that
the NET LED will illuminate to indicate that the scale is now in NET mode.
Method 2: Manually enter a tare.
•With a stable weight on the scale, enter the desired tare weight using the
numeric keypad, followed by the [TARE] key. The NET LED will
illuminate to indicate the scale is in NET mode.
•If the scale was at zero, the tare will be displayed as a negative weight.
The scale cannot be tared if:
•There is a negative weight on the scale.
•The scale is in motion.
•The [TARE] function is disabled. (See Tare Mode - Page 42)
PRINT / SELECT KEY
The [PRINT/SELECT] key has two functions:
Function 1: PRINT a Weigh Ticket to a printer.
•Press the [PRINT/SELECT] key. A ticket will be sent to the
printer connected to an M2000 COM Port. (See the M2000
Printing & Ticket Formatting Guide for more information)
Function 2: SELECT a function.
•Enter the function number on the numeric keypad, followed by
the [PRINT/SELECT] key.
See M2000 Functions – Page 10.

M2000 USER FUNCTIONS
M2000 functions are accessible via the keypad. To prevent accidental misuse,
some functions may need to be enabled upon installation. Additional fine-tuning
may also be recommended to maximize a weighing systems performance. To
help your customer get the most out of the M2000, discuss specific system
requirements with them prior to installation.
SELECTING SCALE CHANNELS
•M2000 Indicators utilize 3independent scale channels. Channel 1 is the
default scale channel.
•To view the weight display for the desired channel, press the channel
number on the numeric keypad followed by the [PRINT/SELECT] key.
•Note the appropriate Scale Channel LED indicator will illuminate.
Scale Channels 2 & 3 must be enabled in Calibration/Set-up Mode.
(See Enable Scale Channel – Page 44)

TOTAL MODE (SUMMING CHANNELS)
•Up to 3 channels may be summed together to display a total
weight.
•Only channels that are enabled and calibrated with the same
grad size, decimal places, and units of weight will be
displayed in TOTAL MODE.
•Channel 1 is always included in TOTAL MODE.
•TOTAL MODE is indicated when more than one of the Scale
Channel LEDs are illuminated.
•To return the M2000 to Single Channel Mode, select a
channel followed by the [PRINT/SELECT] key.
TOTAL MODE EXAMPLE 1:
•A Truck scale with 3 sections.
•Each section is wired to a separate channel on the M2000, allowing the
operator to record the total weight of the vehicle along with the individual axle
weights.
1. To view the rear axle weight (Section 3), select Scale Channel 3.
(CH3 LED will illuminate)
2. To view the total weight (Sum of all sections), enter TOTAL MODE.
Press [4], followed by the [PRINT/SELECT] key. (CH1, CH2, & CH3 LEDs
will illuminate)

TOTAL MODE EXAMPLE 2:
•3Floor scales, each using a channel on a single M2000.
•CH1 and CH3 are calibrated as 2000 x 2 lbs.
•CH2 is calibrated to 500 x 0.2 lb.
As a result, only Channels 1 and 3 will be included in Total Mode.
1. Press [4], followed by the [PRINT/SELECT] key.
2. The CH1 and CH3 LED indicators will illuminate.
3. The weight on the display is the sum of these two channels.
SCALE OPERATIONS IN TOTAL MODE
•Pressing the [ZERO SCALE] button will zero all the channels that are
included in Total Mode.
•The TARE function will tare all channels included in Total Mode
simultaneously, displaying the total NET weight.
•The MOTION and SCALE ZERO LEDs will indicate the status of all the
scales included in Total Mode. (E.g. If Channel 1 has MOTION, Motion
will be indicated for Total Mode)
TOTAL MODE cannot be used in legal for trade applications in
Canada!
CH1 CH2 CH3
TOTAL MODE must be enabled in Calibration before it can be used.
(See Enable Total Mode - Page 45)
