IX. Calibration: Multi-Optional Mode - Direct
Concentration
The Multi-Optional Mode - Direct Concentration calibration procedure is a multi-
point calibration in which one to five standards plus a blank are run in order to
determine the concentration of an unknown. This procedure will also set the
optimal range and sensitivity of the instrument. The Direct Concentration
procedure should be used if you require superior accuracy and wish to determine
the actual concentration of an unknown. The TD-700 will display actual
concentration in the units chosen during setup.
A. To Calibrate
1. To choose the Multi-Optional - Direct Concentration Mode, press
<ENT> from the HOME Screen, press <1> for Setup, then <1> again
for Mode. Use <
↔
> to choose the Multi-Optional Mode.
Press <ESC> to return to the previous screen, then press <2> to
choose the calibration procedure. Use the <
↔
> key to choose “Direct
Conc” for the Direct Concentration calibration procedure.
Press <ESC> to return to the previous screen, then press <3> to
choose the units of measure. Use the <
↔
> key to choose the
required unit of measure. Press <ESC> twice to return to the Setup/
Cal Screen.
2. To access the calibration sequence, press <2> from the Setup/Cal
Screen. The Direct Concentration calibration sequence will appear.
3. When the TD-700 calls for the maximum range (the maximum concen-
tration you want to read), press <1> to accept the current value or <9>
to enter a new value. Range for reentry: 1 - 1000.
4. Key in the number of standards you will be using (1 to 5 concentra-
tions). Press <ENT>.
5. When the TD-700 calls for the “HiStd Conc,” press <1> to accept the
current value and advance to the next screen. Or press <9> to change
the value. Key in the actual concentration of the highest concentration
Standard (Hi Std) you are using and press <ENT>. The numerical
range is 0.1 to 1000. If you are using only 1 standard, IT MUST be
within the linear range for accurate results (see Appendix 1 for a
discussion of linear range).
