Select the High or Low range in SOURCE mode.
◆
Select the Current or Voltage in MEASURE mode.
◆
Activate 24V power.
2. Connect
◆
Complete the pneumatic connection as
shown in Figure 3-17.
◆
For low range differential sensors, connect the
REF/FLT port to the reference port of the gauge
as shown in Figure3-4.
3. Pressurize manually or by the step function
(Section 3.1.11).
4. Record the measure value manually or by using
snapshot (Section 3.1.12) after the pressure has stabilized.
