query.
• Press [Shift] + [1] keys to start entry mode.
Enter the required wavelength, e.g.: [2] for 560 nm.
• Press [ ] or [ ] key to change between plus and minus
sign
• Enter data of the coefficient A including decimal point,
e.g.: [Shift] + [1][.][3][2]
• Press [F1] key to reset numerical input.
Confirm with [ ] key.
• Press [ ] or [ ] key to change between plus and minus
sign
• Enter the exponent of the coefficient A, e.g.: [Shift] + [3]
Confirm with [ ] key.
Successively the instrument queries the data for the other
coefficients (B, C, D, E and F).
Note:
If zero [0] is entered for the value of the coefficient, the
input of the exponent is omitted automatically.
Confirm every input with [ ] key.
Enter measurement ranges from – 2600 to +2600 mAbs.
• Press [ ] or [ ] key to change between plus and minus
sign.
• Enter the values in Absorbance (mAbs) for the upper limit
(Max) and the lower limit (Min).
