IMPORTANT: Displacer must always be completely sub-
merged in one or both process liquids.
1. Bring process up to operating temperature.
2. Establish interface level at desired 4 mA (10%) level
on the displacer. If 4 mA level is at the bottom of
the displacer, 4 mA point may be set with displacer
immersed in upper liquid only.
3. With unit power on, remove cover.
4. Press the ENTER key to start calibration. The
ZERO LED will light. Loop will go to 22 mA.
5. Press the DOWN key to lock in the 4 mA value.
The ZERO LED will flash and remain on. Loop will
stay at 22 mA.
6. Press ENTER to confirm the setting. The ZERO
LED will go off, and the loop will go to 4 mA.
