Calibration
The Shot Meter dispenses a programmed shot amount
based on the measured motion of the pump during the
shot delivery. This provides a precise and repeatable
shot volume. However, the accuracy of the shot amount
may not be sufficient for the application due to many fac-
tors that are dependent on the specific options and
installation. Factors such as the dispense valve, length
of hoses, pressure, and material temperature may affect
the accuracy of the volume dispensed.
To account for these variables, you can calibrate the
delivered volume of each programmed shot. When a
new shot is defined in setup screen #2 the default value
of the calibration factor is 1.00. Decrease this value to
decrease the shot amount. Increase this value to
increase the shot amount. Use the following procedure
to calculate calibration factors. You can set the calibra-
tion factor to any value between 0.20 and 2.00.
Calculate Calibration Factors
To calculate the calibration factor for a shot:
1. Dispense and measure a shot with the calibration
factor set to 1.00 (default).
2. Divide the programmed shot size by the measured
shot size.
If the measured shot is larger than the programmed
amount, the calibration factor is less than 1.00.
If the measured shot is smaller than the pro-
grammed amount, the calibration factor is greater
than 1.00.
3. Enter the result of step 2 into the scale factor setting
in setup screen #2 for the specific shot.
4. Dispense and measure another shot to verify the
calibration. You can adjust the value entered in step
3 up or down fractionally to improve the accuracy of
the shot delivery.
Example
Assume a programmed shot size of 250cc. In this exam-
ple, the dispensed shot size as measured is 271cc. Cal-
culate: 250 / 271 = 0.9225. Enter the amount 0.92 into
the Calibration Factor for the programmed shot.
Restart Shot Sequence
In sequence mode, to restart a shot sequence from the
first defined shot, press and hold the down arrow key for
three seconds. When prompted, hit the top soft key to
confirm restarting the sequence.
Repeat/Skip Shot in Sequence
To repeat a shot, while at the idle run screen press the
down arrow key and confirm when prompted. To skip a
shot, while at the idle run screen press the up arrow key
and confirm when prompted.
