When we will receive an SINPAR Automatic Reference Fuel Blender, firstly the following working conditions in laboratory need to be met, to ensure proper operation of the instrument:
The reference fuel blending unit should be placed on the flat floor. （Note: Do not move the cabinet during operation.）
Installation steps of electronic balance:
Plug the reference fuel blending unit’s power plug into an outlet and switch on the blending unit.
The computer and balance will automatically start when the blending unit is switched on.
The reference fuel blending unit now is ready to perform the first live checks and blending.
Note: Before blending, please check the status indication of Balance, Vessel, Tanks and Valves at the bottom of control panel.
When newly received, the six primary reference fuel tanks are empty and must be filled with iso-octane (ISO), n-heptane (HEP), toluene (TOL), 80/20 blend (80/20), n-cetane (NC), and heptamethylnonane (HMN) or alpha-methyl-naphthalene (AMN), following the corresponding label.
The grade of the primary reference fuels is given in ASTM D 2699, ASTM D 2700, and ASTM D 613.
To fill the tubing and pumps and purge the preservation fluid, the Air Discharge for all the reference fuels should be performed.
Click the “SETUP” button and select the “AIR DISCHARGE” from the SETUP menu.
After the tanks are filled and the air discharge performed, the tubing should be visually checked for leakage due to possible damage during shipping.
Press the “BALANCE” button in the MAIN MENU to calibrate the balance.
Select one type of reference fuels and enter the target volume (100-1000ml), the target parameters of this fuel appear automatically below.
Press “START” button, and wait until the target blending is complete.
Compare whether the difference between the effective value of weight and the target value is within 0.01g.
