Operational Checkout (continued)

CAUTION: Do not simulate an increase in pressure by applying mechanical
force to the sensing diaphragm of the transmitter. Excessive force will result
in damage to or destruction of the transmitter.
When pressure is applied to the transmitter, the display should increase,
and then return to the original reading when pressure is removed. The
Transmitter can be pressurized by lowering it into water or by applying air
pressure from a calibration device.

Mounting

2.4.1 Dimensions
2.4.2 Placement
Caution: The Model 375 Transmitter must be supported by a stainless
steel relief cable that is attached to the tabs on the transmitter. The relief
cable can be customer supplied. Figure 2-2 shows common installation
recommendations. Ametek provides this relief cable as an option. Reference
model number K554164 when ordering. Supporting the transmitter only by
its attached electrical cable voids the warranty.
Caution: Do not allow transmitter to remain in liquid when it freezes solid.
This will apply mechanical force to the sending diaphragm of the transmitter.
Excessive force will result in transmitter damage or destruction.
