Page 6: Adjustments
Adjustments The adjustment weights can be used to check and adjust balance precision at any time. Adjustment weights can be acquired from KERN as an optional component. To decide which adjustment weights are required, refer to Chapter 1 “Technical Data“. -
Page 7: Adjustment Procedure
Adjustment procedure Check that the surrounding conditions are stable, see “Important instructions“. A short warm-up time of about 1 minute is recommended for stabilisation. Display kg/1000 DC688 VrX.XX S - ON 1. Requirements: Turn the adjustment switch on; see Chapter 5 "Adjustments". CAL 00 2. -
Page 8: Control Functions
Control functions Turning the balance on and off Display kg/1000 1. To turn the balance on, press the 8888800 88888800 88888 {ON/OFF} key. The balance will perform a self-test. While reinitialising, horizontal eights (8) will appear on the display. 2. Once the weight appears on the Display, the 0,000 balance is ready for weighing. -
Page 9: Taring
Taring The weight of the containers used for weighing can be tared by pressing a button, such that the net weight of the item being weighed is displayed in subsequent weighing operations. Display kg/1000 1. Place the empty container to be tared on the 0,284 weighing plate. -
Page 10: Parts Counting
Parts counting During parts counting, parts can be added or subtracted from a container. The operating sequence is divided in four steps in both types of counting: • Taring of the weighing container • Defining the reference quantities • Weighing the reference quantities •... -
Page 11: Known Reference Weight
Display kg/1000 Note: If no reference can be created because the item being weighed is too unstable or the reference weight is too small, the balance display will indicate "ADD". In this case, place the desired number of units on the weighing plate and confirm by pressing the {Pcs} key. -
Page 12: Storing The Reference Weight With The Preset Key
6.5.3 Storing the reference weight with the Preset key Six (6) memory registers are available for storing the reference weights of 1000 units. Display kg/1000 1. Enter the reference weight to be stored (e.g., 1,2 53 1.253 kg). 2. Confirm the entry by pressing the 0,000 1,25 {UNIT/WEIGHT} key. -
Page 13: Totalling
Totalling This function allows you to perform several weighing operations. The total number of units and the quantity of weighing operations is then displayed. Display kg/1000 1. Select a reference weight (e.g., 3.56 kg) (see 0,000 3,56 Chapter 6.5.3 “Reference weight with PRESET key“). -
Page 14: Clear Stored Values
6.7.1 Clear stored values Remove the items from the balance and confirm with the * key. The stored values, total number of units and number of weighing operations will all be set to zero. 6.7.2 Automatic shutoff The balance can be shut off automatically, if desired. Depending on the display setting, this option can be used to turn the balance off 3, 10, 30 , 60 or 180 minutes after the apparatus is last used. -
Page 15: Important Information
Important information These electronic scales are a precision instrument. Electromagnetic fields can cause ma- jor display discrepancies. The scales must then be repositioned away from electromag- netic fields. All sources of environmental interference, such as drafts and vibrations, should be avoided. Sudden changes of temperature should be avoided. The scales must be reset to match changes in temperature. -
