Safety

The manufacturer has designed this equipment to be safe when operated using the procedures 

detailed in this manual. The user must not use this equipment for any other purpose than that 

stated. Do not apply values greater than the maximum value stated.
This manual contains operating and safety instructions, which must be followed to ensure the safe 

operation  and  to  maintain  the  equipment  in  a  safe  condition.  The  safety  instructions  are  either 

warnings or cautions issued to protect the user and the equipment from injury or damage. Use

!

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 instrument is powered by an internally mounted 

rechargeable battery - this battery should never be allowed to fully discharge. The input power 

supply voltage limits for the battery charger supplied with the instrument are 90...264 V AC, 50/60 

Hz. 

NOTE:  No other battery charger unit, other than that supplied with the instrument 

should be used.

NOTE:  Do not allow the battery to fully discharge.

                    

!

Pressure Safety

DO NOT permit pressures greater than the safe working pressure to be applied to the instrument. 

The specified safe working pressure (SWP), for this instrument is 350 barg (5076 psig). 

                    

!

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 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

The recommended calibration interval for the MDM300 is 12 months. The instrument should be 

returned to the manufacturer, Michell Instruments Ltd., or one of their accredited service agents for 

re-calibration.

Safety Conformity

This  product  meets  the  essential  protection  requirements  of  the  relevant  EU  and  UK  directives. 

Further details of applied standards may be found in Appendix D.
