5.Rotate the adjustment control counterclockwise to position the shadow line at the bottom of the field of view.

6.Rotate the eyepiece to bring the crosshair into focus.

7.Move the shadow line to the crosshair reticle with the coarse adjustment control.

8.Rotate the dispersion correction wheel to eliminate any red or green color at the edge of the shadow line.

9.Turn the adjustment control to center the shadow line to the crosshair. The shadow line must be perfectly centered to obtain an accurate reading (Figure 3a).

10.Depress the READ button. The value of the test sample will be digitally indicated in the display window. Depressing the TEMP button will activate a temperature sensing device located in the measuring prism. The display will digitally indicate the actual temperature of the measuring prism and sample.

NOTE: If the LEICA ABBE MARK II Refractometer is to be used in an environment where foreign materials may contaminate the display buttons, use the splash guard accessory (Catalog No. 13104590). It will prevent instrument damage and possible instru- ment failure.

capabilities (e.g., Microsoft Works®, Framework II™ and ProComm®)1. Software can be used to store, graph, analyze and print data. Leica also offers LEICA ABBE MARK II Plus Refracto- meter interface software (MARKPLUS) specifically designed for use with the instrument.

The MARKPLUS software allows the instrument user to repro- gram the % Solids scales from the default "Brix" (% Solids) scale to a user defined scale.

7.2 Setting the baud rate

The baud rate of the LEICA ABBE MARK II Plus is set to 9600. To change the baud rate remove the cap on the left side of the instrument (Figure 3b). Turn the instrument on and using the eraser end of a pencil press the post switch which is centered in the hole. The display will show the current baud rate. To change the rate press the read button on the front of the instrument panel until the appropriate baud rate is displayed. Choose the baud rate from the following options: 300, 1200, 2400, 4800, 9600. Once the appropriate baud rate is displayed press the switch again. Turn off the instrument and replace the cap. The new baud rate will be permanently retained in the instrument memory.

7.0 LEICA ABBE MARK II PLUS REFRACTOMETER

NOTE: Sections 7.0 through 7.4 are applicable only for the LEICA ABBE MARK II Plus Refractometer - Model 13104940/13104950.

The LEICA ABBE MARK II Refractometer provides computer interface, custom programming and printer interface capabilities.

The instrument becomes the LEICA ABBE MARK II Plus Refrac- tometer (Model 13104940/13104950) with the addition of the RS232 port. The LEICA ABBE MARK II Plus can be ordered as:

•an original purchase

•a factory upgrade or

•a retrofit to an existing LEICA ABBE MARK II Refractometer.

7.1Computer Interface

Turn on the LEICA ABBE MARK II Plus Refractometer with the switch located on the instrument’s front panel. When the refrac- tometer is first turned on, the software version (e.g., 1.6) will appear in the read display for a few seconds. The refractometer is ready to use when this message disappears.

By interfacing the LEICA ABBE MARK II Plus to a computer, sample reading results can be transferred to IBM-PC compati- ble data-handling software programs with communications

Figure 3a

7.3 Printer Interface

The LEICA ABBE MARK II Plus Refractometer can be interfaced to a serial port printer for printed data results using the 9-pin RS232 output. A parallel port printer may be used with a serial to parallel converter.

7.4 Custom Programming

LEICA ABBE MARK II Plus Refractometer interface software (MARKPLUS) may be configured for customized calibration curves and temperature compensation. (The standard LEICA ABBE MARK II Refractometer corrects to 20OC only.) However, MARKPLUS must be configured for each specific application or custom programming. Leica’s MARKPLUS is designed to accept a Table of Refractive Index, Temperature and Concentration val- ues and then generate custom scale data for instrument pro- gramming. Data is entered from a text file. Contact your Leica representative for more information.
