4.3 Rotating Transmitter Section

The transmitter section can be rotated

approximately 360° (180° to either direction or

between -90° and +270° from the original position

at shipment, depending on the conguration of

the instrument.) It can be xed at any angle within

above range.

1) Remove the two setscrews that fasten the

transmitter section and capsule assembly,

using the Allen wrench.

2) Rotate the transmitter section slowly and stop it

at designated position. For the EJ530 and

EJX630A whose capsule code is A, B or C, the

pipe of the atmospheric opening may interfere

with the stopper and disturb further rotation.

In that case, screw off the pipe rst, rotate the

housing, and then screw in the pipe by hand

again.

3) Tighten the two setscrews to a torque of

1.5 N·m.

IMPORTANT

Do not rotate the transmitter section more than

the above limit.
