To do a pressure switch test: The switch in this example
sets at a high limit of 10 psi. The set condition is a closed
switch contact. For pressure switches, use the Manual Test
selection. For switches where sourcing pressure is not
necessary, use the Auto Test selection to do the test.
1. Connect the test leads between the pressure switch
contact output and the mA Ω RTD (center) jacks on the
Product.
2. Connect the pressure module to the Product, and
connect a pressure line to the switch. Keep the
pressure line vented to atmosphere.
3. If necessary, push  for MEASURE mode.

5. Push  for SOURCE mode.
