8K249 Issue No. 4Change Pressure UnitsTo change the pressure units proceed as follows. If the four units displayed arenot the units required, press TASK and select any task, other than BASIC, pressSETUP and proceed as detailed on page 36. To return to BASIC mode, press TASKand select BASIC.In BASIC mode, the unit is configured to carry out basic Pressure to Voltage (P to V)or Pressure to Current (P to I) tests, a typical test procedure follows.Voltage and Current MeasurementsConnect the electrical input sockets as follows for voltage and currentmeasurements. Use the test leads provided and DO NOT push bare wires into thesockets.Note: Maximum applied voltage = 30V dc,. Maximum input current = 55mA dcGetting StartedNote: Maximum applied voltage for external loop supply = 30V dc
