Battery Information
•To charge the battery, simply plug in the indicator with the included A/C Power Cord.
•Your battery will arrive partially charged from the factory. Prior to using the indicator for the
first time, charge the battery for 10-12 hours to prevent damage and prolong the life of the
battery.
•Battery life can be checked from the light on the right bottom of the display. When the voltage
is getting low, the battery symbol will flicker, and the LCD display will show “LOBAT.” On the LED
display, the red light will flicker.
•Average Charge time: 10-12 hours.
•Average Battery Life with normal use: 30 hours.
•When fully charged, the light turns green on the LED display; the battery symbol shows full on
LCD display.
•If the indicator is not used for an extended period, remove the battery to avoid leakage.
•If you use the indicator regularly, battery life may be extended by fully discharging the battery
every month. To do this, simply leave the indicator on until the battery dies, then plug it in to
recharge it.

CHAPTER 2. INSTALLATION
Power supply connection
The indicator is powered by the included A/C adapter or by the optional 6v battery. Simply plug the
adapter directly into the “DC” port on the indicator housing. This action also charges the battery, if
equipped.
Connection of Load Cell(s) and Indicator
This indicator can power from one to six 350Ω load cells, with either a 4-wire or 6-wire configuration.
There are two methods to connect the load cells to the indicator:
A. Quick disconnect, as below:
4 wire load cell connectors
6 wire load cell connector
For most applications, the BB-200 Indicator comes with a five-pin male plug on the bottom of the
indicator. This pigtail/plug is connected directly to the motherboard on the inside of the indicator.
Having this plug allows you to disconnect the indicator from the rest of the scale, which is convenient
should you need to charge the battery or protect the indicator from theft or weather. The typical
exception to this is if you purchased a stainless steel washdown version of the indicator. In this case,
Option B, below, is preferred, as it provides a better watertight connection.

B. Direct internal connection
The signal cable for load cell (or the junction box) is connected to the Load cell terminal strip on
the motherboard. To make this connection,
1. Open Weighing indicator back cover
2. Insert the cable through one of the strain reliefs on the underside of the indicator
3. Run the cable to the load cell terminal strip, as shown below.
4. Connect the wires as indicated below and ensure that the screws are tightly secured.
For 4 wire load cell, connect EXC+ SIG+ SHD SIG- EXC-.
For 6 wire load cell, remove RJ4 and RJ7 above the terminal trip, then connect SEN+ EXC+ SIG+ SHD SIG-
EXC- SEN-.
Important: Most vendors use a junction box with an internal summing card to combine the signals from
all the attached load cells. However, different vendors use different plugs. Most cables that are used are
simple four or five-pin microphone cables, however even these come in different sizes. B and B Scales,
Inc. typically stocks four and five-pin microphone cables. See www.bbscales.com for more information
about Home Run Cables and load cell cabling in general.
Communication Interface
RS-232/RS-485
The BB-200 supports an RS-232 connection on the motherboard however there is typically not an
external port pre-wired when the indicator ships. You will notice in the packaging that was included with
your indicator that there is a DB-9 RS-232 plug that can be wired to the motherboard and installed. DB9
Pin and 3 Pin are both supported.

If you do not have ananalog input module, adjust a multimeter to the current stalls, series connection
with the 4~20mA.
During Calibration
1. Press[ ] and [ ] go to C32.
2. Show[out-4], the output current should be 4mA.
3. When you press [ ]show[out-5]，Pres[ ]show[out-20]，the output current should be 20mA.
4. Adjust the current as needed, for example, adjust to [out-20], Press [ ] or [ ] to adjust the
current.
Digital I/O Function instructions:
4~20mA corresponds to Zero ~Max. capacity. After pressing ” TARE”, the weight will start from 4mA. Set
C31=0, 0~20mA output mode; C31=1 4~20mA output mode.
If you need 0~5V output, Set C31=0, then connect 250Ω at the two ends of current output, that will get
5 voltage at resistance two ends.
Relay output function (optional)
The indicator can be equipped with up to four optional relays that can be used to control external
equipment based on data gathered by the indicator. This can include controlling actions caused by
weight, piece count, upper or lower weight limits, or other data points that the indicator can identify.
If equipped, these functions are controlled through the C33 menu, as described below.

CHAPTER 3. Basic Operation
This chapter describes the basic operation of the indicator.
Keypad
The indicator is available with either an Light Emitting Diode display panel (LED) or a Liquid Crystal
Display display panel (LCD). Generally speaking, the LCD panel is better for outdoor use, as the
characters are more visible. It can be difficult to read the LED display in direct sunlight, but the LED
display is far preferable in low light situations, such as warehouses, barns, etc.
The LCD display is available in both B and B colors and with the Stull Feeders design. There is no
functional difference between these two indicators.
LCD Version:
LCD Indicator Faceplate
Alternate LCD Indicator Faceplate produced for Stull Feeders
Note that the Stull Feeders Indicator is available in LCD only.

Page 17
By default, when you power on the indicator it will show zero, even if there is weight on the indicator.
This is preferable if you have a squeeze chute, platform, floor scale, or other scale that has a heavy
platform. In most cases, you really don’t care about the actual weight of the scale itself. However, if you
are weighing feed, grain, or another commodity that is routinely not removed from the scale when you
shut it off, you can program the scale NOT to zero when it is first powered on. See Menu C-21 in
CHAPTER 6 to change this setting.
Manual zero setting
Press the key when the scale is stable (and not negative) to zero the display. This is a good habit
to get into every time you are preparing to weigh something.

Important: Some versions of this indicator do not have advanced hold functions. Navigate to C-11. If
you are not able to set a value of 0 to 5, your indicator is not equipped with advanced hold. The only
way to fix this is to upgrade your motherboard. See www.bbscales.com for options.
COUNT
The counting feature allows you to count commodities that weigh the same; things like nuts, bolts, nails,
beads, etc. To use the counting feature:
1. Turn on the scale in normal weighing mode.
2. Identify a known number of your commodity to use a sample, and place it on the scale.
3. Press the button. The display will read, “PCS 0.”
4. Use the and keys (the Tare and Zero keys) to adjust the number of items in your

CHAPTER 4. PROGRAMMING and CALIBRATION
IMPORTANT
This indicator can be commercially Legal for Trade in all 50 states and
Canada. If your scale is certified as Legal for Trade, the following procedures
must be performed by a technician who is licensed in your jurisdiction.
Failure to do so will void your calibration.
WARNING
If you remove or damage the wire seal and/or calibration sticker, your
calibration is void.
Calibration Overview
Calibrating an indicator – almost any indicator – is an exercise in recording the signal the indicator is
receiving from the load cell(s). You need at least two points. One of those points is “zero,” and one of
those points is a known weight placed at a point higher on the graph. This point is called the “Span.”
The closer you can get to true linearity, the more accurate your scale will be. It is typically suggested that
you calibrate a scale with at least 80% of the capacity of the scale. This is not always practical, since you
would need 4000lbs of test weights to calibrate a 5000lb floor scale or livestock scale. Instead, it is good
practice to use a test weight that is close to the weight of what you will actually be weighing.
Test Weights
Certified scale companies and regulatory agencies will typically use test weights that are certified and
traceable to a government standard. If you are doing this yourself, you likely won’t have these. Here are
some acceptable alternatives for scales that do not need to be certified as Legal for Trade:
•Tractor Weights
•Unopened bags of feed, grain or mineral
•Anything made of steel that you know the weight of.
Do not use people or animals or anything that breathes or has a pulse.
