Page 21: Filter Setup
Settling time will be longer as the filter setting is increased. However, the MSI-4260 IS employs algorithms that speed up large weight changes while still controlling vibration even with high filter settings. -
Page 22: Calibration
Calibration The MSI-4260 IS is calibrated using standard weights. It is required that the weight used is at least 10 percent of full capacity in order to achieve rated accuracy. For example, use at least a 500 kg test weight to calibrate a 5000 kg capacity scale. Although a single span point is usually adequate for rated accuracy, the MSI-4260 IS supports Multi-Point calibration with up to four span points plus zero. -
Page 23: Initial Calibration
Use this procedure only if the capacity and count-by (d) need to be modified. The initial calibration erases user setup as well as any previous calibration. Use the following steps to perform the initial calibration procedure. 1. Turn the MSI-4260 IS off. 2. Remove the hex seal screw using the steps in Section 5.1 on page 18. 3. Press the switch and the switch on the unit simultaneously. -
Page 24: Guidelines For Capacity And Resolution
Due to excellent linearity of the MSI S-Beam load cell, it is acceptable to set lower capacities to better match the crane that the MSI-4260 IS is used on. For example, if the hoist is rated for 9000 lb, then use a 10000 lb. weight and reset the capacity to 9000 lb. -
Page 25: C-Cal Calibration
C-Cal. To use C-Cal, a C-Cal number must be known from a previous calibration. MSI supplies replacement load cells for the MSI-4260 IS with the C-Cal value stamped on the serial number label. When a calibration is performed with test weights, a new C-Cal is generated. -

WARNING feature. A thorough load train inspection is necessary to ensure product safety. The MSI-4260 IS maintains two service counters for safety. • The first counter counts the number of times the scale has been overloaded • The second counter counts lifts above 25 percent of capacity These counters serve to warn the user to inspect the load train after a number of overloads and also when there is a chance of fatigue failure. -
