4. Set up calibrator for a Cummins PTD injector.
(See the CD3 calibrator instruction manual.)
5. Install a Flow code 178A injector.
6. Operate the calibrator for 15 minutes.
Test
7. After 15 minutes, turn on the clamp force and
temperature indicator and observe the tem-
perature of the fluid. It should be 104°F ± 1°F,
while the injector is running.
8. If the clamp force and temperature indicator
plus the temperature gauge read the same
(104°F ± 1°F):
a. Disconnect the temperature transducer
from the clamp force and temperature
indicator.
b. Reconnect the supply line to the fuel arm.
c. Skip to Section 2.4. You are finished with
this test.
9. If the temperature is not 104°F ± 1°F, continue
with the following steps.
10. Loosen the lock nut on the TEMPERATURE
ADJUSTMENT control, located on the gauge
panel just below the HEATER ON indicator.
11. Adjust the TEMPERATURE ADJUSTMENT
control until the clamp force and temperature
indicator display stabilizes at 104°F ± 1°F.
NOTE: It takes time for fluid in the
reservoir to mix and the temperature to
stabilize. A small change in TEMPERA-
TURE ADJUSTMENT setting will stabilize
much faster than a large adjustment.
12. After the fluid temperature has stabilized at
104 °F ± 1°F, recheck the temperature indicated
on the CAL FLUID TEMPERATURE gauge.
13. If the gauge and the indicator read the same
(within 1°F), perform the procedures in step 8.
If not:
a. Unscrew the plastic cover on the tempera-
ture gauge.
