Warnings and Cautions

Warning! Follow National Electric Code or your local code safety practices when wiring or connecting this unit to a power source. Only qualified personnel should install and wire the transducer.

Warning! Always remove main power before disassembling the transducer.

Caution! During operation, the mass flow controller valve becomes hot.

Caution! Do not use the manual purge function when RS-485 is active (Model 860 only).

Caution! Always fully neutralize any toxic gas trapped inside the transducer before re- moving from the gas line.

Caution! Only qualified personnel should perform transducer service, calibration or troubleshooting procedures.

Caution! Printed circuit boards are sensitive to electrostatic discharge. To avoid damag- ing the board, follow these precautions to minimize the risk of damage:

before handling the assembly, discharge your body by touching a grounded, metal object

handle all cards by their edges unless otherwise required

when possible, use grounded electrostatic discharge wrist straps when handling sensitive components
