INFO
Pocket calculator functions
The pocket calculator functions are spread over three soft-key
rows:
• Basic arithmetic (first soft-key row)
• Trigonometry (second row)
• Square root, x 2 , 1/x, p (third row)
Use the paging keys to go from one soft-key row to the next.
The TNC always shows an example entry.
Transferring the calculated value
The calculated value remains in the input line even after you leave the
pocket calculator function.
This allows you to transfer the calculated value directly into a pro-
gram as a nominal position — without having to reenter it.
Entry logic
For calculations with two operands (addition, subtraction, etc.):
ä Key in the first value.
ä Confirm the value by pressing ENT.
ä Key in the second value.
ä Press the soft key for the desired operation.
The TNC displays the result of the operation in the input line.
For calculations with one operand (sine, reciprocal, etc.):
ä Key in the value.
ä Press the soft key for the desired operation.
The TNC displays the result of the operation in the input line.
Example: See the next page.
Stopwatch
The stopwatch shows the hours (h), minutes ( ‘ ), seconds ( ‘’ ) and
hundredths of a second.
The stopwatch function continues to run even when you leave the
INFO function. When the power is interrupted (switch-off), the TNC
resets the stopwatch to zero.
