Page 10: Maintenance
CS750, Users Rev S, June 2010 Maintenance Periodic Inspection The crane scale and all associated adaptive devices require periodic inspection and maintenance. The frequency and recording of the inspection requirements are found in service categories below and are dependant on the type of service that the equipment is used in as described below. -
Page 11: Removal From Service Criteria
CS750, Users Rev S, June 2010 3. Inspect for excessive wear of linkages and other mechanical parts. 4. Inspect for excessive wear at hoist hooking points and load support clevices or pins. 5. Inspect for any visible bends or twists of all used rigging devices. -
Page 12: Calibration
1. Press the ON switch. The display does a lamp test; during this time the scale does a quick check of itself. Then the weighing system starts weigh mode. 2. Intercomp recommends that you allow the electronics to operate for three minutes after first turning power on. This allows the electronics to become stable for maximum accuracy before you check the calibrations. -
Page 13: Calibration Switch
CS750, Users Rev S, June 2010 Calibration switch The calibration of the scale is protected from accidental change by a switch just inside the right side panel. Enabling the Calibration switch Using a screwdriver, remove the right side plate and move the switch to “CAL”. - Page 14 CS750, Users Rev S, June 2010 Start up 1. Move the calibration blocking switch to the “CAL” position if you intend to calibrate. 2. Turn scale power ON and wait for scale to warm up (3 minutes from power on).

Page 19: Troubleshooting
CS750, Users Rev S, June 2010 Troubleshooting WARNING : Changing some parts on the circuit board may cause a large change in calibration while others may or may not change the calibration, depending on the nature of the problem. The reference designators for the IC chips are on the “A/D 20-BIT” board unless indicated otherwise. - Page 20 Problem: rechargeable battery life has decreased Fix: The rechargeable batteries provided by Intercomp are high quality, high capacity Ni-Cad. However, all Ni-Cad batteries can exhibit some “memory” effects if they are repeatedly discharged to a certain point before recharging. If your observed...
