** The low battery warning annunciator indicates about two to four hours of additional use before the MSI-4260 IS turns itself off. ** If the MSI-4260 IS is not going to used again soon, remove the SLA battery to prevent deep discharge while the unit is in storage. -
Page 10: Battery Charger
Battery Charger The MSI-4260 IS is shipped with a battery charger, PN 170606, designed to charge and maintain the battery. Exact charging time will depend on the degree of discharge of the battery. A battery removed when the low battery warning first appears should take about eight hours to fully charge. -

Servicing The entire scale must be shipped back to Rice Lake Weighing Systems for repair. Please contact a local dealer or Rice Lake Weighing Systems to obtain a return material authorization (RMA). There are no user serviceable parts within the MSI-4260 IS. -
Page 12: Operation
Navigation of Menus • If a function key does not work, it is probably because the MSI-4260 IS is not set up to support the key. For example, if the function key is set for TOTAL, the TOTAL mode must also be set up in the Setup menu. -
Page 13: Tare
Note The scale digits display 0 (or 0.0 or 0.00, etc) and the weight mode changes to NET. The backup memory in the MSI-4260 IS stores the tare reading and can restore it even if power fails. TARE To clear the tare and revert to gross weight, press displays. -

MSI-4260 IS Port-A-Weigh Display Brightness The Display Setup menu is used to set the display brightness. There are four fixed brightness settings and one automatic light sensing brightness setting. Auto setting will automatically detect the ambient light and adjust the brightness of the display accordingly. Bright light will cause the display to be at the brightest setting. -
Page 19: Setpoints
Setup Setpoints The MSI-4260 IS supports three setpoints. Common uses of set points are for warnings or process control. It comes standard with LED outputs for a triggered set point. Setpoint 1 is Blue Setpoint 2 is Green Setpoint 3 is Red Figure 4-1. -
Page 20: Total
MSI-4260 IS Port-A-Weigh Total For the accumulation of multiple weighments, the total function uses the displayed load, so gross and net readings can be added into the same total. There are four modes of totalizing: manual and three auto modes. The manual mode requires the TOTAL key be pressed with the weight on the scale. -
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% 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. -
Page 23: Standard Calibration
Calibration Standard Calibration Use the following steps to calibrate the MSI-4260 IS using the standard calibration procedure. TARE 1. Press , displays. TARE 2. Press when the scale becomes motionless. A blinking displays. • If the scale is in range displays, then displays 3. -
Page 24: Initial Calibration
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. -

Page 27: Auto Zero Maintenance
Auto Zero Maintenance The MSI-4260 IS employs an Auto Zero Maintenance (AZM) mechanism to adjust the zero reading to the center-of-zero, which is defined as the weight reading within 1/4 d of zero. AZM continuously adjusts zero to maintain the center-of-zero. It is recommended that AZM is on to maintain the highest accuracy. -
