How Do I?

1) With no flow, record the counts in raw data (:22) and enter that value in Min Raw (:62) and MinIn

(:72).

2) Enter 0 in MinOut (:92).

3) Run pump station in as close to a full flow condition as possible. The higher the flow, the more

accurate the calibration.

4) Record the counts in raw data (:22) and enter that value in MaxIn (:82).

5) Measure milli amp signal in series with positive input to the analog board. Write this number

down.

6) Subtract 4 mA from this reading. Write this number down.

7) Use the Model 310 Calibration chart to select the correct pipe size for the programming installed

on the Model 310. Go to the Max GPM @ 20 mA column, and record that number.

8) Divide the maximum GPM by 16 and write down that number.

9) Multiply that number (GPM per mA) by the adjusted mA reading from step 5.

10) Enter this number in MaxOut (:102).

For Example: You have a pump station with an 8 inch flow meter spool. Therefore, the maximum

GPM @ 20 mA is 3000 GPM. Start at step 5. Your mA reading is 14 ma. Subtracting 4 mA from

this reading gives you an adjusted reading of 10 mA for step 6. The max GPM @ 20 mA is 3000

GPM for step 7. Dividing this value by 16 yields 187.5 GPM per mA for step 8. Multiply the

adjusted reading of 10 mA from step 6 by 187.5. Your answer is 1875 GPM. Enter this value in

MaxOut (:102).

Tap the value next to any of these registers to open the calculator/keypad. Enter or edit the value.
