d. If problems still exist, check the drive shaft,
pump shaft or motor shaft binding and
replace necessary parts.
14. If speed is normal, turn circuit breaker OFF.
15. Reinstall the wire on the interlock limit switch
in its original position at the center screw.
16. Reinstall the pulley cover.
17. Turn the power switch on the side of the
calibrator to ON.
18. Push the START MAIN DRIVE button on the
front of the calibrator.
19. While the calibrator is operating, open the
pulley cover.
NOTE: For older units use a sliding
pulley cover, slide the cover ½ inch toward
the back of the stand.
The calibrator will stop automatically if wiring is
correct and the system is functioning properly.
2.2 CALIBRATION FLUID VISCOSITY
CHECK
Viscosity of the calibration fluid has a marked
influence on the flow test of an injector. Note that
viscosity changes with fluid temperature. This test
applies only to fluid specified in the CD3 manual.
Equipment Required
• Viscor cup with instructions and chart (Make
sure the number on the chart and instructions
match the number on the cup.)
• Temperature transducer assembly
• Clamp force and temperature indicator
• Container - Minimum 2 quart, maximum 8
quart, with minimum 3 in. diameter opening
and maximum 6 in. high
• Stop watch
Setup
1. If calibration fluid was not saved when prepar-
ing for audit (Section 1.3), drain a minimum of
1-½ quarts of calibration fluid from reservoir
into a clean, dry container - Minimum depth 5
inches.
