5.0 Calibration
The Dyna-Link 2 is calibrated using standard precision test weights. It is required that
the weight used is at least 10% of full capacity in order to achieve rated accuracy. For
example, use at least a 500kg test weight to calibrate a 5000kg capacity unit. The
Dyna-Link 2 supports load cell linearization with up to four span points that can be
calibrated in any order. Usually only one cal span point is necessary and is sufficient
to reach rated accuracy.
When adequate test weights are not available, the Dyna-Link 2 can be calibrated using
a constant calibration which is referred to as C-Cal. To use C-Cal, a factory generated
C-Cal number must be known. MSI supplies original and replacement load cells for
the Dyna-Link 2 with the C-Cal value stamped on the serial number label.
There are three aspects of calibration:
• Standard calibration - used for maintenance and routine calibration.
• Initial calibration - used to setup both the capacity and resolution (d) of the Dyna-
Link. It differs from standard calibration only in the initial steps. Initial
calibration is performed after a calibration reset which completely erases the
calibration and setup memory.
• C-Cal - If C-Cal values are known, the Dyna-Link can be calibrated without
weights.
5.1 Calibration Menu
The calibration menu contains three items: Cal, C-Cal, and auto zero maintenance.
The following procedures start with entering into the Cal menu, or for an initial
calibration, resetting the Dyna-Link 2 and then going to the Cal menu.
