Procedure 2:
The SITRANS LG200 transmitter also allows the level points to be entered automatically.
As above, a twenty point table is available. However, with this procedure, the user can
allow the SITRANS LG200 to use the present level as the strapping table entry.
1. Scroll down to the Strapping Table parameter and press enter, Pt01Lvl is displayed.
2. Press and hold the ENTER button, then press the UP arrow at the same time. (The
present level reading is now captured and entered into the strapping table.) Press
enter and the display shows Pt01Vol.
3. Enter the corresponding volume and press enter.
4. Add a known liquid volume to the vessel.
5. For the remaining points, add a known liquid volume to vessel and repeat steps 2 to
3.
Dielectric (Dielctrc)
Select range bounding the dielectric constant of the media. The LG200 uses this dielectric
setting to adjust the Sensitivity setting. (User password)
The lower the dielectric setting, the higher the sensitivity. In applications where the
dielectric may vary, enter the range for the minimum dielectric for your application.
Selection is fixed at 10-100 for 7ML1301-5. For Interface Mode (7ML1301-6 only), select
10-100
Notes:
1. All twenty strapping table points do not have to be used.
2. Strapping table point values can be entered or changed in any order.
3. All strapping table points must be larger than the previous entry. If not,
the strapping length will stop at that entry.
