变量名称： ftbFunc

变量ID： 0x40BB

变量标签： Function FTB

变量描述： The tank bottom tracing system (see Sect. 8.6.15 of 'Operating Manual') is activated under this function: · OFF The FTB is deactivated; the device operates in the standard mode. · PARTIAL When this option has been selected, the tank bottom tracing system is activated only in the vicinity of the tank bottom, i.e. at low levels (max. 20% of the tank height but a minimum of 0.6 m). Given higher levels, the normal measuring method is used (reflection from the product surface). This method is sufficient for most applications with poorly reflecting products. The parameter "Epsilon R" must be as exact as possible. · FULL (for BM 70 A only) When this option is selected, the tank bottom tracing system is activated over the total measuring range (tank height). For tank heights above 16 m, however, measuring accuracy is additionally affected. The parameter "Epsilon R" must be as exact as possible. (Fct. 3.5.7)
