Electrical Safety

The instrument is designed to be completely safe when used with options and accessories supplied by
the manufacturer for use with the instrument. The input power supply voltage limits are 90 to 260 V AC,
47/63 Hz.

Pressure Safety

DO NOT permit pressures greater than the safe working pressure to be applied directly to the instrument.
Refer to the Technical Specifications in Appendix A.

Toxic Materials

The use of hazardous materials in the construction of this instrument has been minimized. During normal
operation it is not possible for the user to come into contact with any hazardous substance which might be
employed in the construction of the instrument. Care should, however, be exercised during maintenance
and the disposal of certain parts.

Repair and Maintenance

The instrument must only be maintained either by the manufacturer or an accredited service agent. Refer
to www.michell.com for details of Michell Instruments' worldwide offices contact information.

Calibration (factory validation)

Prior to shipment, the analyzer undergoes stringent factory calibration to internationally traceable
standards, NPL (UK) and NIST (USA). Due to the inherent stability of the instrument, only periodic
calibration is required under normal operating conditions.
Michell Instruments recommends that calibration of the sensor should be maintained on a 12 monthly
basis to ensure optimum operation. Michell Instruments offers a calibration exchange program, where
a refurbished and re-certified sensor is supplied as an operational replacement and the original item
returned to Michell to complete the exchange.
NOTE: This interval may need to be reduced if the operation of the sensor is within potentially
aggressive or corrosive sample media (such as sour natural gas). The calibration interval
may therefore need to be shortened to 6 months (or lower in extreme cases) in order to
maintain satisfactory analyzer performance.

Safety Conformity

This product meets the essential protection requirements of the relevant EU directives. Further details of
applied standards may be found in the product specification.
