Introduction
Congratulations on choosing the new MicroGuard®510 Retrofit Rated Capacity Indicator System.
This manual describes the calibration process for the MicroGuard®Retrofit Rated Capacity Indicator
System (hereinafter referred to as “the system”) in an on-site environment and assumes that there
is no prior knowledge of the geometry of the crane other than data provided by the manufacturer.
This document also assists personnel in obtaining necessary measurements for calibration and in
maintaining a record of the measurements and test results for review and/or comparison when
changes are made. Recording measurements and test results during the calibration process will
ensure an organized and easy to follow calibration.

Required Tools
1/4” nut driver or T15 Torx driver•
Digital or bubble level calibrated and accurate to 0.1° at level•
100 foot measuring tape: fiber type graduated in tenths of feet•

Typical Tape Measure

Tape Measure
graduated in tenths
of a foot
Note: The computer calculates measurements in feet and tenths of a foot, so having the
correct measure will facilitate entering measurements.
Digital volt/Ohm Meter capable of measurements to three decimal places•
Number Conversion
If you are using a standard tape measure, the measurement must be converted into feet and tenths
of a foot. For example: a distance of 35’–6” would be entered into the system as 35.5 feet. Whole
inches can be easily converted by dividing by 12 (6/12=.5). Fractions of an inch are converted
by dividing the numerator by the denominator. For example: 1/4 inches would be entered as .25
(1/4=.25). Conversion of whole inches and fractions of an inch (for example 6-1/4”) are converted
by first converting the fraction to a decimal and then dividing by 12. In this case 6-1/4” is converted
to 6.25 and then divided by 12 which equals 0.520. Refer to the Fraction to Decimal Conversion
Chart on page A-5.
When entering weights, the number must be converted by moving the decimal three places to the
left. For example: a weight of 1,400 pounds would be entered as 1.4, and a weight of 300 pounds
would be entered as .300.

The MicroGuard®510 Display
Command Entry
The keys that are identified as A, B, C, and Dwill be used most for the procedures described in this
document and their function will vary depending on the routine being performed. Commands for each
routine will show in the information window as text adjacent to the keys. Follow directions for each
routine carefully.
Number Entry
The display does not have a numerical keypad so when numbers are required, the display will change
to enable number entry.
Keys Band Dare used to scroll left and right. The “cursor” will appear as flashing < > brackets on
either side of the number. Key Ais used to enter the number. Key Cis used to exit the number entry
subroutine.
As each number is selected, press key Ato enter it into the system. The number will then appear
in the [ ] brackets. Up to five numbers may be entered. When entering a negative value, enter the
numbers and decimal first, then enter the minus sign. If you enter a number incorrectly, select the
< backspace and press key A. When all digits look correct, press key Cto calibrate the complete
number.
Example: To enter the value “-2.98”, do the following:
Press key1. Bor Duntil the number “2” is selected (indicated by flashing < > brackets) and then
press key Ato enter the number
Select the decimal “.” then press key2. A.
Repeat the previous steps to enter the number “9” and “8”.3.
After the numbers are entered, press key4. Bor Duntil the minus sign “-” is selected and then
press key A.
If the value is correct, press key5. Cto exit.

Preliminary Checks and Measurements
The following pages provide a list of measurements that must be recorded and double-checked for
accuracy. If measurements exist in the system from a previous application, or if no measurements
exist, they must be entered into the system. Any data supplied by the crane manufacturer in the
crane application data sheet stored in the system must be validated before calibration begins. All
dimensions entered into the computer must be in feet and tenths of a foot.

The boom should be in a horizontal position (0°) when taking the following measurements. Use the
space provided in Appendix A to record the measurements:
Dimension “L” – The horizontal distance between the center of the boom pivot and the center of the
boom hoist cylinder upper pivot.
Dimension “J” – The vertical distance between the center of the boom pivot and the center of the
boom hoist cylinder upper pivot.
Note: If the Boom Pivot is above the boom hoist cylinder upper pivot the dimension is or negative.
Dimension “G” – The horizontal distance between the center of the boom pivot and the center of the
boom hoist cylinder lower pivot.
Dimension “H” – The vertical distance between the center of the boom pivot and center of the boom
hoist cylinder lower pivot.
USE THE SPACE PROVIDED IN APPENDIX A TO RECORD THE MEASUREMENTS.

Dimension “H0” and H1” – The vertical distance between the center of the front and rear winch
(respectively) and the center of the boom pivot.
Dimension “J0” and J1” – The distance between the top sheave and the centerline of the boom pivot
parallel to the horizontal boom plane (measurement may be identical).
Note: If the boom pivot is above the boom hoist cylinder upper pivot as shown in the illustration,
dimension “J” will be negative. Make sure to indicate a positive (+) or negative (-) value when noting
the measurement.
Dimension “L0” and “L1” – The distance between the centerline of the boom pivot perpendicular to
the horizontal boom plane and the center of the bottom sheave (measurement may be identical).
Dimension “N” Swing Offset – The horizontal distance between the center of the boom pivot and the
centerline of rotation.
Note: If the centerline of rotation is ahead of the boom pivot as shown in the illustration, the
dimension will be negative. Make sure to indicate a positive (+) or negative (-) value when noting the
measurement.
Dimension “R” Sheave Radius – The distance between the center and the outside edge of the bottom
sheave.
USE THE SPACE PROVIDED IN APPENDIX A TO RECORD THE MEASUREMENTS.

Boom Cylinder Dimensions
M
Dimension “M” –This is the distance measured around the outside of the cylinder rod, divided by 12.
USE THE SPACE PROVIDED IN APPENDIX A TO RECORD THE MEASUREMENTS.
Span Dimensions
mWARNING
SETTING SPANS ON THE CRANE WILL REQUIRE FULL EXTENSION OF THE BOOM. MAKE SURE
THE CRANE IS SET UP ACCORDING TO THE MANUFACTURER’S OPERATION MANUAL TO
ENSURE MAXIMUM STABILITY. ALSO MAKE SURE ALL BOOM EXTENSIONS AND LOADS ARE
LIFTED WITHIN THE APPROPRIATE LOAD CHARTS AND LIMITS. FAILURE TO COMPLY WITH
MANUFACTURER’S LIMITS MAY RESULT IN SERIOUS INJURY OR DEATH.
Dimension “S” - This is the distance between the center of the boom pivot and the center of the
sheave with the boom fully retracted.
T
S
Dimension “T” - This is the dimension between the center of the boom pivot and the center of the
sheave with the boom fully extended.
The span of the boom is calculated by subtracting Dimension “S” from Dimension “T” (T - S = span).
USE THE SPACE PROVIDED IN APPENDIX A TO RECORD THE MEASUREMENTS.
