MI 3288 EI Tester Safety and operational considerations
10
This equipment should be recycled as electronic waste.
Warnings related to measurement functions:
Working with the instrument
❑ Use only standard or optional test accessories supplied by your distributor!
❑ Always connect accessories to the test equipment and to the test object before starting
measurement. Do not touch test leads or crocodile clips during measurement.
❑ Do not touch any conductive parts of equipment under test during the test, risk of electric
shock!
❑ Make sure that the tested object is disconnected (mains voltage disconnected) and
de-energized, before connecting the test leads and starting the measurement!
❑ Do not use a current measurement as an indication that a circuit is safe to touch. A
voltage measurement is necessary to know if a circuit is hazardous.
❑ The instrument automatically discharges tested object after finished measurement.
❑ It is recommended to use the GUARD connection when high insulation resistance
(>10 GΩ) is measured.
❑ Insulation resistance measurements shall be performed on de-energized objects, i.e.,
voltage between test terminals should be lower than 300 Vac and 50 Vdc!
❑ Earth resistance measurements shall be performed on de-energized objects, i.e.,
voltage between test terminals should be lower than 30 Vac or dc!
❑ Ohm resistance R7 measurements shall be performed on de-energized objects, i.e.,
voltage between test terminals should be lower than 10 Vac or dc!
❑ Ohm resistance R200 measurements shall be performed on de-energized objects, i.e.
voltage between test terminals should be lower than 5 Vac or dc!
❑ PASS / FAIL indication is enabled when limit is set to ON. Apply appropriate limit value
for evaluation of measurement results.
Warnings related to Batteries:
❑ Use only batteries provided by the manufacturer.
❑ Never dispose of the batteries in a fire as it may cause them to explode or
generate a toxic gas.
❑ Do not attempt to disassemble, crush or puncture the batteries in any way.
❑ Do not short circuit or reverse polarity the external contacts on a battery.
❑ Keep the battery away from children.
❑ Avoid exposing the battery to excessive shock/impacts or vibration.
❑ Do not use a damaged battery.
❑ The Li – ion battery contains safety and protection circuit, which if damaged, may
cause the battery to generate heat, rupture or ignite.
❑ Do not leave a battery on prolonged charge when not in use.
❑ If a battery has leaking fluids, do not touch any fluids.
❑ In case of eye contact with fluid, do not rub eyes. Immediately flush eyes
thoroughly with water for at least 15 minutes, lifting upper and lower lids, until no
evidence of the fluid remains. Seek medical attention.
