Replacing parts
The MHM 100 monitor has a number of renewable parts and items that need
regular replacement in order to maintain optimum hygiene and efficiency. All
parts can be purchased via the Corporate website
• Electrode pads – these are for single use only. Additional packs of
electrode pads are available for purchase. Abrasive wipes – these are
supplied with each order of Electrode pads.
• Electrode lead – although designed to withstand normal handling, it is
non-repairable and may sustain permanent damage if not handled or
stored correctly. You should therefore inspect the lead regularly for
signs of excessive wear and tear, such as cracked plastic wire casing,
and replace it if damaged. It is important to replace damaged leads as
they can produce inadequate reports
• Computer lead and USB to serial adapter – any damage to these
two items could prevent you from transferring your results to your
computer, so it is essential that you store them carefully and replace
them if necessary
• Batteries – a set of two high-quality AAA alkaline batteries has enough
energy to perform one test and collect the results. We recommend that
new batteries are used for each test. Please refer to ‘Inserting and
replacing batteries’ for more information on suitable battery types.
How to look after the MHM 100
Do not attempt to dismantle the MHM 100 as this will invalidate its warranty.
It is recommended that you store the monitor and its leads in the bags
provided in between tests. This will help protect them from accidental damage
and reduce the need for purchasing replacement parts.

Cleaning
The MHM 100 is not waterproof and so should never be immersed in water or
cleaning fluid; it is not suitable for dishwashers or washing machines. If
necessary, the MHM 100 should be carefully cleaned by wiping the external
surfaces with a damp cloth and soap. If further cleaning is required, you can
use a surgical wipe.
