Required Tools
•
Small, flat-blade screwdriver
NOTE:
Normally, replacing restrictors or connectors
will not affect calibration.
Before troubleshooting (Table 1), ensure that:
1.
The supply pressure at the unit is constant
(± 2 psi) 22 psi (152 kPa).
2.
All transmitter inputs being used are between
3 and 15 psi (21 and 103 kPa).
3.
Only one restrictor (internal or external)
supplies
each transmitter.
4.
The transmitter calibration is correct.
