Calibrating the Flow Meter

Although the default settings were determined by using typical adhesive
specific gravity values, if you want the most accurate adhesive output
readings, it is strongly recommended that you calibrate the flow meter. You
will need the following to do this task:
S
Refer to the Material Data Sheet (MDS) for the Specific Gravity value
for the adhesive you are using. You will need this number.
S
An electronic scale and an aluminum pan. Make sure to "zero" out the
weight of the pan.
S
Wear protective gloves and eye wear.
S
The melter must be in a Run state with the pump enabled.
1. Go to Home | System Settings | Flow Settings and enable the
Adhesive Flow Monitoring option.
S
Refer to the adhesive Material Data Sheet (MDS) and locate the value for
Specific Gravity. Go to Home | System Settings | Flow Settings |
Adhesive Settings and select Specific Gravity. Press the > button on
the navigation pad and enter the specific gravity for your adhesive. The
default is 0.95. The minimum is 0.80 and the maximum is 1.20.
2. Go to Home | System Settings | Flow Settings and select Reset
Totals
3. Place the aluminum pan under the applicator or applicators and start
dispensing adhesive. The larger the sample the better. You will need to
collect at least 28 grams. Make sure to wear hand and protective eye
wear. When done, place the sample on the electronic scale. Write down
this value.
S
Navigate to Home | System Settings | Flow Settings and write down
the Adhesive Usage value. Compare this value what you have
measured.
S
If the two values are the same or very close, within a 1/10
sufficient, then press < to return to the Flow Settings menu or
to return to the Home screen.
S
If the two values are not close, then you need to calculate a new
Calibration Constant Setting as follows.
‐
Current Constant Calibration Factor * Displayed Adhesive Usage / the
weight you measured.
