3.2 Three Part Calibration
3.2-1 Calibration Introduction
CAUTION: Read all the instructions prior to performing
each calibration procedure. Always contact Cascade prior
to performing any calibration procedure. Failure to follow
instructions exactly will change the accuracy of the iForks
and could compromise the system's ability to weigh.
There are three parts to calibrating iForks. Some cases only
require a portion of the Three Part Calibration to be performed.
Refer to chart below. A summary of each part is as follows:
• Zero Calibration – Determines and sets the zero point for
the iForks system.
• Corner Calibration – Takes any inconsistency between the
load cells (corners) and equalizes them with each other.
• Weight Calibration – Determines and sets the weight range
for the iForks system by using a sample of known weight(s).
When to Calibrate ■ Calibration Procedures ◆
When the iForks are not within system tolerance.
Perform Zero Calibration (Section 3.2-3) and Weight
Calibration (Section 3.2-5) with at least one known weight
When the weighing range does not meet end user
preferences.
Perform Zero Calibration (Section 3.2-3) and Weight
Calibration (Section 3.2-5) with at least one known weight
When the display or wire harness has been replaced. ●
Perform Zero Calibration (Section 3.2-3), Corner Calibration
(Section 3.2-4) and Weight Calibration (Section 3.2-5)
◆ CAUTION: Always perform the tasks and calibration in
the order listed.
■ CAUTION: Always use proper handling and troubleshoot
the iFork assemblies first before calibrating. Inaccuracies
can occur when debris becomes wedged into and
between the fork shoe and arm. Always use calibration
as a last option.
● IMPORTANT: Prior to calibration, the iForks system must
have an established connection between the iForks

receivers and the display. Refer to Section
3.3-1.
