50-613 Kotron Series 82 CE RF Level Transmitter

7. If 20 mA cannot be reached, individually close Span

Coarse DIP switches (in sequence), #1, #2, and #3, until

the loop current is close to (and not less than), 20 mA.

(ONLY ONE SWITCH POSITION SHOULD BE

CLOSED AT A TIME—THE OTHER TWO

POSITIONS MUST REMAIN OPEN).

8. Turn the Span Fine potentiometer counterclockwise until

the loop current is exactly 20.00 mA. If 20 mA cannot be

reached, repeat Step 6.

Calibration is now complete.

1.7.2 Calibration Procedure B

1. Move the media level in the vessel to the lowest level you

can set.

2. To determine the correct output level at this point, use the

following formula:

3. Turn the Zero Coarse potentiometer counterclockwise

until the loop output is between L1mA and

L1mA + 0.5 mA.

4. If the loop current output cannot be decreased to at least

L1mA + 0.5 mA, turn the Zero Coarse potentiometer

fully clockwise, close Zero Coarse DIP switch positions #2

and #3 sequentially (ONLY ONE SWITCH POSITION

SHOULD BE CLOSED AT A TIME—THE OTHER

TWO POSITIONS MUST REMAIN OPEN). Repeat

Step 3. See Figure 10.

5. Turn potentiometer Zero Fine counterclockwise until the

loop output reads exactly L1mA.

6. Move the media level in the vessel to the highest level you

can set.

7. To determine the correct output level at this point, use the

following formula:

8. Turn the Span Fine potentiometer counterclockwise until

the loop current reaches the desired value calculated

(L2mA) in Step 7.

9. If the desired value cannot be obtained, individually close

the Span Coarse DIP switches #1, #2, and #3, until the

loop current is as close to (and not less than), L2mA.

(ONLY ONE SWITCH POSITION SHOULD BE

CLOSED AT A TIME—THE OTHER TWO POSI-

TIONS MUST REMAIN OPEN).

10. Turn the Span Fine potentiometer counterclockwise until

the loop current is exactly L2mA.

Calibration is now complete.

L2mA = (

(L2 - L0) x 16) + 4

(L3 - L0)

L1mA = (

(L1 - L0) x 16) + 4

(L3 - L0)
