4. Press ENTER key to start calibration. ZERO LED 

will light. Loop will go to 22 mA.

5. Press DOWN key to lock in 4 mA value. Zero LED

will flash and remain on. Loop will stay at 22 mA.

6. Press ENTER to confirm setting. ZERO LED will 

go off, and loop will go to 4 mA.

7. Establish water at the point on displacer equal to the

lower S.G.

100% (EX. 0.98 

×

100% = 98%).

8. Press ENTER key. ZERO LED will light. Loop will 

go to 20 mA.

9. Press UP key to lock in 20 mA value. ZERO LED will

go off. SPAN LED will light. Loop will go to 20 mA.

10. Press ENTER to confirm setting. ZERO LED will

3.4.4.3.2

Lower S.G. greater than 1.0.
When S.G. of lower liquid is greater than 1.0, 
calibrate as follows (this example assumes upper 
S.G. = 0.78 and lower S.G. = 1.20):

1. Bring process up to operating temperature.
2. Establish water at the point on displacer equal to the

upper S.G.

100% (EX. 0.78 

×

100% = 78%).

3. Ensure there is no explosion hazard. With unit 

power on, remove cover.

4. Press ENTER key to start calibration. ZERO LED 

will light. Loop will go to 22 mA.

5. Press DOWN key to lock in 4 mA value. Zero LED

will flash and remain on. Loop will stay at 22 mA.

6. Press ENTER to confirm setting. ZERO LED will 

go off, and loop will go to 4 mA.

7. Immerse displacer completely in water.
8. Determine the proper current setting for this cali-

bration step using the following calculation: [(20 
mA - 4 mA) 

×

(1.00 - upper S.G.)/(lower S.G - 

upper S.g.)] + 4 mA (EX. [(20 mA - 4 mA) 

×

(1.00 

- 0.78)/(1.20 - 0.78)] + 4 mA = 12.38 mA).

9. Press ENTER key. ZERO LED will light. Loop will 

go to 20 mA.

10. Press UP key to lock in 20 mA value. ZERO LED 

will go off. SPAN LED will light. Loop will go to 
20 mA.

11. Using UP and DOWN keys, toggle until loop signal

reads 12.38 mA.

12. Press ENTER to confirm setting. The SPAN LED 

will go off.
