DIESEL TEST PROCEDURE

MICRO-SEPAROMETER MARK V DELUXE OPERATION MANUAL 12.0 DIESEL TEST PROCEDURE 12.1 Prepare the DELUXE MICRO-SEPAROMETER as stated in section 7.0. 12.2 Momentarily depress the "ON" switch. The annunciator lamps located on switches A through G in the TEST SELECT section will then be scanning for your selection. Depress switch "D". This will initiate the standard automatic program for Diesel fuel. 12.3 The annunciator lamp on the "START" switch will be illuminated which indicates the program can be started by momentarily depressing this switch. 12.4 Remove a plunger from a 50 ml. syringe, insert a plug in the bottom, add approximately 50 ml. of fuel to be tested, place the syringe on the emulsifier turning to lock in place. Caution should be exercised to center the emulsifier blade in the syringe (Figure 5). Press the "START" pushbutton which will automatically clean the syringe for approximately 30 seconds and also raise the syringe drive to its UP position. 12.5 Add about 15 or 20 ml. of the fuel to be tested to a clean vial and insert into the TURBIDIMETER (the hole directly above the PROGRAM and METER sections). Align the black vial mark with the white line on the front panel. 12.6 Remove the syringe from the emulsifier, empty the fuel, draining thoroughly, and add exactly 50 ml. of test fuel. 12.7 Using a fresh tip on the hand pipette, add 50 microliters of clean water to fuel sample as follows. Push in plunger, immerse tip just below the water surface, release the plunger and withdraw from the water slowly to avoid water drips adhering to the outside of the tip. Immerse the tip of the pipette just below the fuel surface in the center of the syringe, to ensure the water drops break away cleanly and fall to the bottom; push the plunger, withdraw the pipette, and then release the plunger. 12.8 Place the syringe on the emulsifier, turning to lock in place. Caution should be exercised to center the emulsifier blade in the syringe (Figure 5). COPYRIGHT 1984 EMCEE ELECTRONICS, INC. REVISION DATE: FEBRUARY 12, 1987 PAGE 13
