Link-Belt MG-534 Calibration ii W450160 10/07

Link-Belt MG-534 Calibration 1 W450160 10/07
Introduction
This manual describes the calibration process for the Link-Belt MG-534 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•
Minimum 100 foot measuring tape (200 foot may be required) - fiber type graduated in•

1.0′
1′-0″ 1′-1″ 1′-23/4″
1.1′ 1.23′
Typical Tape Measure
graduated in inches
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.
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.

Link-Belt MG-534 Calibration 2 W450160 10/07
Number Entry
The system display does not use a numeric keypad. Instead, a range of numbers and characters is
assigned to a particular key.
To select a particular number, press the key adjacent to the
number until it is selected by flashing brackets < >.
When entering negative numbers, select the negative symbol
( - ) first.
Decimal points are entered the same as numbers.
After the desired symbol or number is selected, press the
key adjacent to the number entry field (enter key) to enter the
number.
If an error is made in data entry, selecting the “<” symbol and pressing the enter key will delete one
character. Selecting the “C” symbol and pressing the enter key will erase the entire entry.
Once the desired numerical value is entered, press the key adjacent to Exit. Press the key adjacent
to YES! Calibrate! to confirm the entry.
Press the key adjacent to Exit to cancel the number entry procedure.
