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.
