The 5HIHUHQFH￿*DXJH￿+HLJKW is the distance from the Upper Reference Point to the bottom of the tank (see Figure 4-1 on page 4-2). When setting the Reference Gauge Height, keep in mind that this value is used for all level and volume measurements performed by the 3300 transmitter.

The Reference Gauge Height must be set in linear (level) units, such as feet or meters, regardless of primary variable assignment.

The 8SSHU￿1XOO￿=RQH (UNZ) should not be changed unless there are

disturbances at the top of the tank. By increasing the Upper Null Zone value measurements in this region can be avoided. See 6HFWLRQ￿￿￿￿'LVWXUEDQFHV￿DW￿ WKH￿WRS￿RI￿WKH￿WDQN for more information on how to use the UNZ. The UNZ is

equal to zero in the factory configuration.

3UREH

The 3300 Series transmitter automatically makes some initial calibrations based on the chosen 3UREH￿7\SH. The following Probe Types are available:

•Twin Lead

•Flexible Twin Lead

•Coaxial

•Rigid Single Lead

•Flexible Single Lead

127(

Flexible and Rigid probes require different radar electronics and can not be used with the same transmitter head

The 3UREH￿/HQJWK is the distance from the Upper Reference Point to the end of the probe, see Figure 4-1.If the probe is anchored to a weight do not include the height of the weight.

The 3UREH￿$QJOH is the angle between the probe and the vertical line. Set this value equal to zero if the transmitter is mounted with the probe along the vertical line (which is normally the case).
