SAFETY WARNINGS
n
Safety warnings and precautions
must
be
read and understood before
the instrument is used. They
must
be
observed during use.
n
The circuit under test
must
be
switched off, de-energised and isolated
before test connections are made when carrying out insulation and
continuity tests.
n
Continuity of protective conductors and earthed equipotential bonding
of new or modified installations
must
be
verified before carrying out an
earth fault loop impedance test, RCD or earth testing
n
Do not touch
circuit connections and exposed metalwork of an
installation or equipment under test. Under fault conditions the system
earth could become hazardous live.
n
Do not touch
the earth stakes, test leads and their terminations
(including connections to the earthing system under test) if an
installation earth fault can arise unless adequate precautions are taken.
n
The ‘live circuit warning’ and ‘Automatic discharge’ functions are
additional safety features and
should not
be regarded as a substitute
for normal safe working practices.
n
Do not move
the rotary switch positions while a test is in progress.
n
Do not operate
the instrument or connect it to any external system
if it shows any visible signs of damage or if it has been stored for
prolonged periods in unfavourable conditions.
n
Do not operate
the instrument or connect it to any external system
if the battery compartment or casing is open or any parts of the case
(including keypad, selector switch, display window, etc.) are missing.
n
Always disconnect
the instrument from all systems while batteries are
being changed or the fuse replaced
n
Do not replace
the rechargeable cells in the MFT1730 and 1835 with
non-rechargeable “dry” cells and attempt to charge the cells. This can
cause explosion or fire.
n
Do not operate
the charging equipment supplied with the MFT1730 or
MFT1835 in damp or wet environments or outside. All test leads
must
be
removed from the instrument while charging.
n
After insulation tests, capacitive circuits must be allowed to discharge
before disconnecting test leads. Locking the Insulation test ON
should
only be used
where there is no risk of a circuit holding a charge.
