Warnings and Cautions
Warning! The sensor validation procedure must be performed with the power off.
Warning! Do not open the flow meter enclosure in an hazardous area.
Caution! The flow meter must not be reporting or measuring gas flow during adjustments.
Caution! Adjusting zero or span will affect meter calibration.
Caution! To ensure back up of the factory settings, download and save the flow meter
variables using the Smart Interface software.
Caution! Do not change the flow meter’s factory full scale setting.
Caution! Do not power the flow meter with the sensor jumper wires disconnected. This could
cause over-heating of the sensors and/or damage to the electronics.
Caution! During the validation procedures the output of the meter will be forced from
the zero condition to the full scale condition. Make sure that any monitoring system is in
the manual mode during validation.
Caution! Printed circuit boards are sensitive to electrostatic discharge. To avoid dam-
aging 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
