HOW TO SET UP AND OPERATE THE SYSTEM
Note: Typical six pad arrangement (Figure 2) allows for easy weighing of
both two and three axle vehicles. Plan to weigh groups of the same type
vehicles for most efficient operations.
BATTERY OPERATION
Note: Turn the ON/OFF Switch to OFF when weighing is not taking
place to extend operation time before battery recharge is required.
1) Set the weigh pads on a firm level surface to achieve the best
accuracy. Weigh pads are completely interchangeable and may be
connected in any order with the same system. Do not interchange
between systems.
2) Connect the cables as shown in figures 2, 3, or 4, with color of
cable connector matching color of pad connector at each connec-
tion.
CAUTION: Snap cable strain reliefs to eyelets in weigh pad handles.
3) Turn the meter ON/OFF Switch to ON. Verify that all display
segments and lamps light during the segment check (88888). Wait
until the program nunber has been displayed and a stable reading
appears on the display.
4) With the weigh pads unloaded push the ZERO Switch to zero the
display.
5) To check calibration push the Cal Switch and compare the
number on the display with the Cal number stamped on the serial
number tag under the meter lid. If the numbers are different,
remove the SPAN adjust cap and adjust the span screw until the
numbers agree. Release the Cal Switch and verify that the display
returns to zero. Replace the Span cap.
6) Close the meter lid to prevent moisture and/or dirt from entering
the meter.
7) The system is now ready for weighing operation. Use two weigh
pads per axle.
Note: Ensure that only one wheel on each side of duals is centered on the
pads.

8) The following additional procedure should be followed to gain
axle as well as total vehicle weights:
8a) Drive vehicle onto front two pads.
8b) Record weight.
8c) Continue forward and place all vehicle wheels onto pads and
record total.
8d) Subtract front axle weight (8b) from total weight (8c) to

meter labeled POWER.
CAUTION: Ensure proper pin alignment. Do not attempt to force
connector into place.
4) Operate the system as in Battery Operation steps 1-8.
Note: The engine of the vehicle to which the system is connected
should be running to ensure constant 12 Volt power availability.
CALIBRATION PROCEDURE
The Bantam has been calibrated at the factory and is ready for use.
Recalibration of the system may be accomplished should the Bantam
weight readings differ significantly from those obtained at a certified
scale.
Note: The Battery should be fully charged for this operation.
1) Turn the ON/OFF switch to on, verify that all display segments
and lamps are on during the segment check, then off again before
the program number is displayed (P-XX).
2) With no load on the weigh pads wait for a stable display reading
and push the zero switch to zero the display.
3) Push the Cal Switch. The Cal number (found on the serial number
tag under the meter lid) should appear on the display. If the
displayed Cal number agrees with the Cal number on the serial
number tag, skip to step 5.
4) Adjust the SPAN screw with the Cal switch pushed until the
proper calibration number appears.
5) Release the Cal Switch and verify that the display returns to zero.
If not, repeat steps 2-4.
Note: Perform the following steps for each weigh pad.
6) Connect an unloaded weigh pad to the meter.
7) Push the ZERO switch to zero the display.

8) Apply a calibrated load to the center of each weigh pad. This may
be accomplished by loading the weigh pad with a truck wheel
previously weighed at a certified scale. Best results will be
obtained by loading the pad as near to the rated pad capacity as
possible.
Note: An unconnected weigh pad should be placed under the opposite
wheel on the axle for the most accurate results.
9) Remove the cap screw located on one side of the weigh pad under
the handle (see Figure 1).
10) Turn the adjustment screw until the meter displays the correct
weight.
11) Remove weight from the pad and check for return to 0, Repeat
steps 2 through 10 if the meter does not return to 0.
12) Replace the cap screw.
13) Repeat steps 2 through 12 for each pad.
Note: Measurement Systems International, Inc., will calibrate, for a
fixed charge, systems that are returned to the factory. Systems must be
returned freight prepaid.
INTERNAL ZERO ADJUSTMENT
If the display reading is greater than a few percent of the system weight
capacity when the meter is first turned on (with no weight on the pads),
you may want to internally re-zero the meter as part of the system
calibration procedure since the overrange capacity of the meter may be
affected. To acconplish this do the following:
1) With all weigh pads connected and unloaded, remove the four
front panel screws. Lift the front panel out away from the meter
case to expose the circuit boards on the rear side of the panel.
Find the zero adjust control screw near the bottom of the com-
puter board (rear board) slightly left of the center.
2) Turn the ON/OFF switch off, then on again and wait a minute for
the display to stabilize. Then adjust the zero control screw until
zero is displayed.
3) Turn the meter off and replace the front panel, the meter is left on
when actual weighing is not taking place.

BATTERY CHARGING
Battery life is a function of several variables, including battery age,
battery charge, temperature and the number of pads connected. Battery
life will be reduced if the meter is left on when actual weighing is not
taking place.
Note: Turn the ON/OFF switch to OFF when weighing is not taking
place.
Low battery voltage is indicated by a flashing Low Battery lamp below
the display. The battery is charged by connecting the meter to an A.C.
power source with cable 40035-8 indicated by the illumination of the
CHARGING light. When the charge lamp is illuminated (and the A.C.
power connected) the battery has recharged to at least 80% of full
capacity.
Note: The ON/OFF Switch should be in the OFF position for fastest
charging.
The internal battery may be allowed to charge continuously. A fully
discharged battery will reach 80-90% of full capacity within 16 hours if
the ON/OFF switch is in the OFF position. Frequent recharging will give
the longest battery service life. Poorest service life is obtained when the
battery is allowed to fully discharge before each recharge.
A fully charged internal battery will typically power the system for about
20 hours. With the printer option the discharge time is reduced to 6-8
hours with the printer on, or 12 hours with the printer off.
BATTERY REPLACEMENT
The battery is located in the meter. The following procedure should be
followed if a defective battery needs to be replaced.
1) Order a replacement battery from your dealer or from Measure-
ment Systems International, Inc.
2) Turn the meter off. Carefully remove the panel to access battery.
Remove the four screws securing the front panel.
3) Remove the screw securing the battery hold-down plate and
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

remove the plate. Unplug the battery connector and remove the
battery.
Note: If the printer option is installed further disassembly is required
since the plate cannot be removed. Unplug all wires going to the power,
pad and printer connectors on the right side of the meter case. The four
nuts inside the feet on the bottom of the meter case. The entire internal
chassis assembly may now be removed from the case. Unplug the battery
and slide out sideways without removing the battery hold down plate.
4) Install the new battery and reassemble the meter.
5) Charge the battery for 16 hours.
