NOTE:

See Figure 4-1 on page 4-3 for a map of the programming menu structure and how to access all the menu options.

To change the 20 mA level:

a)If entering the menu system from the PV display, press the green button ↓ repeatedly until the “S-20” menu option is indicated (see above note.)

b)Ensure the target is the 20 mA level and, with the display indicating that level, press the blue button →.

c)The display indicates the present 20 mA level setting, not the new level reading. If this value is correct, press the red button ↵ and then the green button to get to the next menu option.

d)Press the blue button → to start editing. The display flashes alternately “20” and the new level reading.

e)Press the blue button → to confirm the new level reading is the new 20 mA level.

f)If the new 20 mA level is correct, press the red button ↵ to save. The display changes to the next menu option.

g)If the new 20 mA level is incorrect, press the blue button → to exit to the menu. The menu option “S-20” re-appears; re-start at step (b) or press ↓ for the next menu option.

Learn About Echoes From False Targets

The MSP422 has an easy-to-use “Lrn” (Learn) routine that allows the instrument to learn up to two false echoes, which can then be ignored in future operations.

If the application is simple and there are no false echoes, press the green button ↓ to exit the integral display menu and return the instrument to indicating the level reading on the display.

If an echo other than the true liquid surface echo is detected and an incorrect level reading is indicated, the instrument can learn to ignore this false echo. The “Lrn” routine may be used at any time, either during or after setting-up or if a problem occurs later.

NOTE:

See Figure 4-1 on page 4-3 for a map of the programming menu structure and how to access all the menu options.

To store a false target echo:

a)If entering the menu system from the PV display, press the green button ↓ repeatedly until the “Lrn” menu option is indicated (see above note.)

b)Press the blue button → to enter the “Lrn” menu. The display indicates “LrnX” where “X” (0, 1 or 2) is the number of stored false target echoes.

c)To exit to the menu at this stage, press the red button ↵ and then the green button ↓ to get to the next menu option.

d)To store a new false echo, hold the blue button down → for five seconds.

e)The display now alternately flashes “Lrn” and the false target position. After four seconds, the false echo target position is stored and the display re-indicates “LrnX” alternating with the distance to the stored echo.
