3 Operation
Typical operation of the Quick Balance is covered below, followed by explanations of
the various display modes, how to change wire size, how to change the unit of
measure, etc.
3.1 Typical Operation
Take readings at three different places along the cable, moving the tension meter at
least four inches for each reading. Take the average of the readings. The built-in
average function is ideal for this task.
The handle quick release pin should be used when the Quick Balance is attached to a
cable that will be de-tensioned and retensioned. The pin prevents the handle from
opening once the tension falls to a small level. The pin should also be used if the
Quick Balance will be installed for a prolonged period.
To perform a typical tension measurement, see the note above and follow these steps:
1. Turn the unit on by pressing the ON/OFF key…
The display shows DILLON briefly, then, in this example, the screen
shows the following:
Figure 3.1 Sample display
Press the WIRE key to list the stored calibrations.
2. This example shows the wire is a 1/2”, 8 X 19 stranded cable and the unit of
measure is lbf. Place the Quick Balance so the two outside sheaves hang on
the wire. Insure that the wire rope is riding in the groove of all three sheaves.
See Figure 3.2. Press the Zero softkey to zero the display.
0 should be displayed.
3. Raise the lever arm until it locks in the upright position to apply tension to the
wire. Read the line tension on the display.
Quick Balance User Instructions 11
4. Release the lever arm and you are ready to perform another measurement.
Figure 3.2 Quick Balance attached to cable
3.2 Measurement Practices
For best measurement, install the Quick Balance at least 2 feet (0.6 m) from
terminations, clamps or other hardware. Do not install over the top of wire wrappings.
Take readings at three different places along the cable, moving the tension meter at
least four inches for each reading. Take the average of the readings. The built-in
average function is ideal for this task.
Do not apply tension greater than rated capacity of the instrument or overload
damage to the sensor may result.
Do not use the Quick Balance with cable larger than indicated on the sheaves.
Overload and damage to the instrument may result.
Do not mix sheave sizes. This will result in inaccurate measurement and possible
overload.
Do not use the Quick Balance to measure tension for wires if both of the following are
true:
1. No wire calibrations are stored of the same diameter as the wire you are looking
to measure, and
2. You do not have sheaves of the same diameter.
If both of these conditions exist, contact your Dillon distributor.
Contact your Dillon distributor to improve accuracy for a specific wire type by calibrating
to it.
Insure that the wire rope is riding in the groove of all three sheaves.
12 Quick Balance User Instructions
Insure sheaves installed agree with sheaves noted in the Wire calibration. Exception:
Sheaves match the wire diameter of the cable to be measured and alternate calibration
is selected as per section Calibration to Specific Wire Type on page 22.
The Quick Balance has an internal temperature sensor inside the electronics cavity.
Dramatic temperature changes (such as moving from a warm vehicle to cooler
outdoors) requires time for the sensor to reach the same temperature. Direct sunlight
will heat the electronics cavity and cause higher readings than actual ambient
temperature. In these cases, use a seperate thermometer to determine temperature.
Be certain to enter this temperature into the Quick Balance if using the quick-tensioning
mode with the temperature dependent acceptance window.
For best tension accuracy, use the exact temperature of the wire. This may be widely
different from the ambient temperature if the cable has been sitting in direct sunlight.
3.3 Softkey Functions

the reading is in Fahrenheit or Centigrade and if the temp is one that was
Entrd (entered) manually.
You can enter the temperature in one of two ways; let the Quick Balance
determine the ambient temperature automatically or key in a temperature
manually. Instructions for entering the temperature are under the Temp
softkey description.
Upper and lower thresholds for the Check-tensioning mode, discussed below, are set
in the Configuration WIRE menu.
Check-tensioning Mode: Check-tensioning mode permits quick & easy
graphical view of the applied tension versus the desired tension. This
mode works well when you are repeatedly tensioning to the same tension
range. This mode displays a bar graph representation of the tension being
applied. See Figure 3.4. The black bar represents the range of the wire,
from zero to ultimate wire rating. The wide white band is the tolerance
window based on upper and lower thresholds you can enter. The live force
is represented by the arrow and the white line on the black bar. When the
force gets within ±5% of the acceptance window, a close-up of the
acceptance window is displayed. See bottom example in Figure 3.4.
The Quick Balance has automatic tension targeting with temperature.
Points may be entered from a linear Tension-Temperature supplied table
for a wire cable. If entered, the check-tensioning window will automatically
float according to the active temperature (manual or automatic). Use the
bottom and top entries from the table. Patent is pending on this feature.

5 Changing Sheaves
Screws
Do not use the Quick Balance with cable larger than indicated on the sheaves.
Overload and damage to the instrument may result.
Do not mix sheave sizes. This will result in inaccurate measurement and possible
overload.
As you use the Quick Balance on different diameter cables you must change to the
correct sheave size. To change sheaves, remove the hex head screws pointed out in
Figure 5.1 below. Replace the sheaves with the correct letter sheave and reinsert the
screws and tighten.
Insure sheaves installed agree with sheaves noted in the Wire calibration. Exception:
Sheaves match the wire diameter of the cable to be measured and alternate calibration
is selected as per the instructions in Calibration to Specific Wire Type on page 22.
Insure that the wire rope is riding in the groove of all three sheaves.

6 Achieving Best Accuracy
6.1 Accuracy
The Quick Balance is an instrument designed to give accuracy that typically exceeds
normal requirements for wire tensioning. You should have an understanding of what
factors affect tension measurement accuracy.
6.2 Calibration to Specific Wire Type
While it is best to have the instrument calibrated to the specific wire size(s) and type(s)
used, the Quick Balance can often work adequately in other situations. If the best
tension accuracy is required, Dillon recommends that a calibration be performed for
that specific wire size and type.
Contact your Dillon distributor for any additional calibrations you may need.
6.2.1 What Calibration Choice and Sheaves Should I Use?
Situation Wire calibration selection Sheave selection Accuracy
Exact wire size and type is
shown in wire list
Wire size is same, but type
is not identical
Wire size is not the same Closest diameter Sheaves matching the wire size
Description of exact match Sheaves noted in list Best
Description of same wire diameter Sheaves noted for that wire size Good
being measured
Do not use the Quick Balance to measure tension for wires if both of the following are
true:
1. No wire calibrations are stored of the same diameter as the wire you are looking
to measure, and
2. You do not have sheaves of the same diameter.
If both of these conditions exist, contact your Dillon distributor.
Contact your Dillon distributor to improve accuracy for a specific wire type by calibrating
to it.

6.3 Loading Error
A tensiometer works by deflecting the cable, which makes the cable path longer than
when a tensiometer is not installed. When the tensiometer is removed, the wire tension
decreases as the cable length is restored. This effect is known as loading error. The
Quick Balance design elongates the cable by a mere 0.08 inch (2 mm), making loading
errors extremely small.
6.4 Non-repeatability
The Quick Balance’s sheave with bearing design provides the best mechanical
performance. It is also superior at detecting tension that is being added or removed.
6.5 Non-linearity
Most three-point tension meters employ only linear characterization and have large
errors at the midpoints (up to 15%). The Quick check uses multi-point segmenting to
correct for non-linearity, reducing it to less than 0.2%.
6.6 Wire Characteristics
Creep Every material including steel exhibits creep under load. It will neck down
over time, quite quickly over the first few seconds and much slower as
time progresses. A wire cable also sees creep from the wire spacing and
wind. This effect is seen as a display that drifts lower after it has been
clamped in line.
Variations Material that varies in diameter or shape will have different output at the
same tension
Strands The best cable assembly is one that is perfectly round, as it will not
change contact geometry with the wire twist. The closer the wire cable
cross section appears to be round, the better the measurement
performance will be.
