The optional Scientech keyboard provides direct access to a variety of preprogrammed weighing modes incorporated into your
Scientech balance. By following the simple instructions and examples, you will find that both complex and routine weighings
are easier than ever. This option may be purchased at any time but must be installed at the factory. To get started, plug the
keyboard connector into the mating connector at the rear of the balance with the power off. Then turn on the balance. You may
remove the keyboard connector at any time without disturbing the current balance mode of operation.
Numeric Keys
Numbers entered through the keyboard appear in the balance display after the numeric key is pressed. Numbers consisting of
seven digits plus a decimal may be entered. Key-in numbers by pressing the numeric keys in sequence. The decimal point must
be keyed in if it is part of the number.
Example: Key in the number 256.78 by pressing the keys 2 5 6 . 7 8 .
The display will read 256.78 .
Any numbers keyed into the display can be sent to peripheral instruments by pressing the Send key.
Clearing Numeric Entry
Pressing the CE (clear entry) key clears any number entered into the display and leaves the display blank awaiting the correct
entry. This key is useful for erasing errors made while entering numbers into the display. Errors can be cleared without
disrupting the mode of operation.
Clearing Programmed Operation
Pressing the C (clear-all) key erases all functions, returns the balance to its normal operating condition, and tares the balance
which returns the display to zero. Information entered into the balance storage registers is unaffected by the C key.
