TMP- 2.3.0 CHECK PDIAL TO 520 mmHg
a) PULL on the syringe plunger to create negative pressure.
b) Clamp the 'to syringe' tubing segment.
c) Remove the syringe then reattach it.
d) PULL again. Can you make screen 0's PDial reach at least -520 mmHg?
Yes -520 at PDial! See procedure number
No Cannot achieve -520! Proceed to
TMP- 2.3.1 CHECK PDIAL ZERO
a) Remove the syringe and ALL clamps to open the four way to atmosphere!
b) ENSURING the transducer protector, at the meter, is NOT wet, does screen 0's PDial = 0 +/- 40?
Yes PDial = 0 +/- 40! See procedure number
No PDial IS NOT between 0 and 40! Proceed to
).
