and press to return to Menu Options screen.
Adjust Set Point - Allows for a single set point calibration using distilled
water. This option is covered in more detail under Set Point Calibration.
Adjust Span Point - Allows up to six additional calibration points to be used
when performing a span point calibration. The proper use of this option is
covered in more detail under Span Point Calibration.
Edit Data - This option allows the stored calibration values to be modied.
Follow the on screen instructions pertaining to changing values, advancing
and exiting this option.
Restore Factory - Restores original factory default settings. This option
cannot be used as a substitute for an actual calibration procedure.
Channel
The option to select a channel is only available if a custom channel has been
stored. To select any available channel, advance to Channel and press

Mode
The choice of four reading modes are available. Additional reading modes
may be available if a custom channel is active. To change mode, select the
required mode option and press to activate.
Index - Refractive index.
Index-TC - Refractive index temperature corrected.
Solids - Percent concentration (Brix).
Solids-TC - Percent concentration temperature corrected (Brix).
An alternate method of changing modes exists in the reading screen once a
sample has been measured. All that is required is to press the or
keys to advance through the available reading modes on the LCD screen.
Language
English, French, Spanish and German are available language options. To
activate one of these options, advance to the language of choice and press

Automatic Temperature Equilibration
Temperature equilibration of a sample to that of the refractometer is essential
for accurate measurements. Automatic temperature equilibration will detect
when the sample and prism have reached thermal stability. This option can
either be turned off or set between +/-0.01
o
C to +/-0.10
o
C. A lower selected
temperature value will increase the sensitivity and time for the sample to
reach temperature stability. Some experimentation is required to determine
the best setting for a specic application.
To properly use this feature apply the sample and press the key. After
the Mark III displays that the temperature of the sample is stable, align the
shadowline and press to attain the sample value.
