8.2.8. K-Factor Calculate
(continued)
Note: For most accurate results, use a
graduated container as the receiving vessel.
Note: The operator must predetermine the
amount that will be pumped into the receiving
vessel prior to starting the K-Factor Calculate
process. This is the amount that will be entered
into the meter during Step 3 of the process.
1. Press ENTER to start trial batch and
automatic calculation. The Batch
Controller starts counting pulses from
the sensor.
2. When the fluid level in the receiving
vessel reaches the predetermined
amount, press ENTER to stop
calculation. At this point, the Batch
Controller stops counting pulses from
the sensor. (Any fluid that comes out
of pump discharge during the motor
throttle down period has not been
counted by the meter and should not be
added to the final volume.)
3. Enter the predetermined volume and
press ENTER
4. The Batch Controller is calculating the
new K-Factor.
5. Successful K-Factor calculation. Press
ENTER to accept new K-Factor or ESC
to return without saving.
Note: The K-Factor is based on a constant
flow. During a specific batch, the motor
must remain on the same speed as when
the K-Factor was calculated. Changing the
speed of the motor in the middle of a batch
will cause an inaccurate reading in the batch
control module.
Helpful Hints:
• Speed potentiometer on motor should
be turned to “Max” to ensure ow
chamber is full during calibration
process.
• The predetermined amount of uid that
will be pumped during the K-Factor
Calculate process should be no less
than 3 gallons or 12 liters.
• Using a larger receiving vessel than
the amount you plan to pump for this
process will decrease the turbulence
of the liquid in the container, thereby
making it easier to stop the meter at the
predetermined volume.
• For increased accuracy, repeat the
K-Factor Calculate process three times,
notating the calculated K-Factor after
each process. Then take the average
of these K-Factors and manually enter
this value to any of the seven available
presets (see section 8.1.2)
8.2.9. ASEC
ASEC (Automatic Systematic Error
Compensation) improve instrument
performance. ASEC works starting from
application’s parameter, particularly sensor
body’s material and pipe’s size. To set ASEC
OFF makes Size and Material Options
useless, so it makes them unavailable from
Calibration Menu (Figure 30).
Note: Leave ASEC setting “OFF” as it does
not apply to this model.
9. Troubleshooting
The instrument correctly installed is
maintenance-free. The case and the front
panel can be cleaned with soft cloth and an
appropriate cleaning agent.

the example consider Batch Volume = 100 L)
• Check and repair the cause of the leakage

SET VALUE
MORE THAN 0
• K-Factor cannot be set to 0
• Batch Volume cannot be set to 0
• Overrun alarm volume cannot be set to 0
• Volume lled into the tank (during K-factor
calculation procedure ) cannot be set to 0
• Enter K-Factor value from 000.01 to 99999
• Enter any volume from 0.0001 to 99999
• Enter any volume from 0.0001 to 99999
• Enter any volume from 000.01 to 999.99
K FACTOR

• The value calculated during the KFactor
calculation procedure is out of range
• Move decimal point p osition
