Digital Measurement Tool Instructions
The Digi-Belt™ tension measurement tool is easy to use and gives repeatable belt
tension measurements. The following instructions for use define the procedure
for different belted applications. You must have the force deflection values for
the system you are working on. These values are readily available from your belt
and machine manufactures.
Model 3000-110 Maximum Deflection Force 110 lbs.
Model 3000-220 Maximum Deflection Force 220 lbs.

Section 1
Digi-Belt™ Basic Single & Multi Belt Tensioning Procedure
1. Look up the recommended measurements and tension values from the belt manufacture and or
the machine provider
2. Measure belt span. (See Drawing 1)
3. Position O-ring on the tester scale at this measured length. The scale is 10” per increment. 150”
Maximum Span. (Picture 2)
4. The BT 357D Tension Tester is already configured to test and measure belts. To begin simply
press the power on/off button.
5. Zero the BT-357D by pressing the ZERO button
6. Place the tip of the Deflection Span Scale on one belt, at the center of the span.
7. Loosen the brass lock nut, then adjust the position of the Deflection Span Scale up or down on
the adjustment rod until the ZERO line (see picture 2) is even with the adjacent belt or even with
the lasers. (B.A.T. Belt Alignment Tool Method as described in section 2)
8. IF needed again Zero the BT-357D by pressing the ZERO button
9. Apply a sufficient force to BT-357D to deflect the belt such that the O-ring is in-line with the
other belts. Maximum force of Model 3000-110 is 110lbs.
10. For increased accuracy or if this is a single-belt drive, use the angle brackets and the B.A.T. Belt
Alignment Tool Method as described in section 2.
11. Read the deflection force on the BT-357D display
12. Compare this force with the value given on the chart or table supplied by your belt manufacture.
13. Zero the reading in the BT-357D and remeasure to verify results.
14. If the force is below the recommended value, increase the drive center distance to provide
greater belt tension.
15. Reduce the center distance if there is too much force.

5. Set Up and Measurement for the Angle Brackets & Laser Bats
1. Mount Mag brackets to pullies as shown. (Diagram 3)
2. Mount the steel adapter plates to the Mag brackets as shown. (Diagram 3 &4)
3. Mount 2 BATS flat on the Mag bracket adapter plates as shown. (Diagram 3 & 4)
4. Adjust the BATs so the green lasers are on the opposing BAT center white Glowline® targets.
5. Press the power on off button on the BT-357D.
6. Zero the BT-357D by pressing the ZERO button

8. Loosen the brass lock nut, then adjust the position of the Deflection Span Scale up or down
on the adjustment rod until the lasers are on the ZERO line (see picture 2 above)
9. IF needed again Zero the BT-357D by pressing the ZERO button. (See Picture 5)
10. Apply a sufficient force to BT-357D to deflect the belt such that the O-ring is in-line with the
lasers. Maximum force is 110lbs.
11. Read the deflection force on the BT-357D display
12. Compare this force with the value given on the chart or table supplied by your belt

Wide and Banded Belt Tensioning Procedure
1. Procedure for using the wide belt adapters for wide belts, banded belts, toothed belts, timing
belts etc.
2. Select the Wide Belt Adapter bar the best suits the belt being tested.

The new BT-357D Series digital force gauges are the
choice for simple, cost-effective tension and compres-
sion testing.Combining one of the most compact hous-
ings, yet maintaining a large back-lit LCD, these units
were designed to fit perfectly in the hand for ease of
use. The multi-language BT-357’s provide menu pro-
gramming for intuitive set-up of the instrument to your
desired requirements. Three modes of operation are
selectable: Track mode displays live readings, Peak
mode records the maximum reading sensed during the
test, and Pre-set mode which activates user defined
high and low limit set points. The programmable lim-
its provide a quick visual and audible indication if a
test passes or fails. In addition, a comparator output
enables integration of the instrument into your qual-
ity system for repetitive testing such as on production
lines.
The display graphics facilitate user comprehension
and operation. An analog bar graph provides perspec-
tive of current reading in comparison to the full scale
range. Pass/Fail icons provide an instant response of
the testing outcome while a storage symbol acknowl-
edges when a reading is logged. A menu-selectable
display orientation streamlines switching from push to
pull testing for portable or test stand applications.

3.3 Select Test Mode
The FG-3000 has 3 types of Test Modes.
Track: The real time measuring mode. Under this mode, press the
ZERO key to tare any initial reading being displayed.
Peak: In Peak mode, the maximum force will be recorded and
displayed. Press the ZERO key to reset the peak value.
Preset: Enables the setting of an upper and lower limit to com-
pare to the measured force value. A simple GO/NG analysis is
displayed on screen via icon indicators for quick pass/fail testing.
To guarantee an accurate test, make sure to zero the display and
tare any small force being displayed before beginning the test.
There are two means to select your appropriate Test Mode. At the
home screen simply press the MODE key to scroll through the
three measuring modes.
You can also select the mode under the Measurement menu in
the Test Mode sub-menu. See Fig. 3-3(a)
If the Preset is selected, a new screen will pop up where you can
set the Upper and Lower limits. See Fig 3-3(b)
Press ZERO to adjust the number and press MODE to move to
the next digit.

Fig. 8-1
5.6 Calibration
Because of the sensor material performance or the influence of
external factors, there may be errors of a certain level after
a period of usage.
It is recommended to send the force gauge to a specialized test-
ing organization for calibration.
If you have standard force weights or other standard load and a
test stand, you may utilize this function and procedure to calbrate
the sensor.
Fig. 5-6(a)
1) Mount the force gauge.
2) Use the tare by use of the ZERO key.
3) Enter Calibration sub-menu as in Fig. 5-6(a).
The calibration interface is shown in Fig. 5-6(b).
Fig. 5-6(b)
4) Load a standard force. Now the value in the standard input area
is just equal to the current measured value. Wait a moment for the
force to stabilize.
Fig. 5-6(c)
5) Press ZERO and MODE to input the standard force value.
6) Press MENU to enter the next calibration. Press LOG to inter-
rupt the calibration.
When 3 calibration points have been finished, a confirm window
will pop up asking to “Save and Exit”(YES)/(NO). Fig. 5-6(d)
Press ZERO or MODE to select, then press MENU.
If “YES” is selected, Calibration is complete. Fig. 5-6(e)
10. TROUBLESHOOTING

8.2 Setpoint Output
Two NPN open collector setpoint outputs are available.
The internal circuit of the setpoint output is shown as Fig 8-2.
Pin7 with Pin6 will be connected when an overload alarm occurs.
In Preset Mode, Pin7 to Pin6 is connected when the measured
value exceeds the upper limit. Pin4 to Pin6 is connected when the
measured value passes below the lower limit.
CAUTION: Maximum permissible voltage: pin 7 to 6, pin 4 to
6 must be lower than 35V ; pin 6 to 7, pin 6 to 4 must be lower
than 6V .
Remember to remove the load after measurement. Applying a
load for a long time period may affect the accuracy of the instru-
ment.
9. MAINTENANCE
9.1 Maintenance
After use, please keep the instrument body clean. Do not let oil
and other substances persist on the body and screen so as not
to damage the instrument. Remember to remove the load after
measurement. Applying a load for a long time period may affect
the accuracy of the instrument.
9.2 Charging
When the battery is low, the icon “ ” will be displayed. The
batteries should be charged immediately.
Connect the gauge and the charger with the USB cable. Then
connect the charger with AC socket to start charging.
