Instructions
Automotive Multimeter
Precautions
Always refer to instructions before use.
When using the multimeter please observe al normal safety precautions concerning
protection against the dangers of electrical current.
Do not used the test leads if they are damaged or the insulation or wires are bared in any
way.
Take care when working with voltages above 35V DC or 25V AC rms; these voltages are
regarded as a shock hazard.
Before rotating the Function / Range rotary switch (F) to another function, disconnect the
test leads from the circuit under test.
Do not use the multimeter in a potentially explosive atmosphere or where flammable
gases or material are present.
Do not perform resistance, diode or continuity tests on live circuits. Always discharge
filter capacitors in power supplies and disconnect the power when making resistance or
diode tests.
Never apply voltage or current to the multimeter that the exceeds the specified maximum
as shown in the tables above.
Always refit the test probe covers when finished with meter.
Observe standard workshop safety procedures when using the tester.
Do not let the tester get wet or use in damp or wet conditions.
