Zeile❖To finally carry out a direct voltage measurement, you have topress key .The third line of the display for the measurement of voltage isactivated.In doing so you have prepared the voltage adapter formeasuring voltage with help of the pressure channel p3.Remark:By pressing either key or you canselect between pressure- and voltage measurement.Only the corresponding pressure sensor or adapterneeds to be connected to the measuring input p3.The calibration values entered previously, remain inthe instrument.If you request a measurement of current, you will have to act inthe same way as for themeasurement of voltage.5. Programming of pressuredifferential measurementPrecise pressure differential measurements are only possible, ifboth pressure sensors have been aligned before, on onepressure level, at which the later measurement shall be made.For this, both pressure sensors p1 and p2 have to bemechanically connected to the same pressure level via adistributor (see scheme: pressure differential alignment).* * * PROG DP * * *alignment P1/P2 withthe same pressure!ENT-> confirmYou can invoke the alignment of the pressure sensors by thestroke of key and key.The following display appears. The alignment is started by theconfirmation with "ENT".-11-
