Safety Summary
1. ELECTRICAL SAFETY

WARNING! It is the responsibility of the owner and the operator to read, understand and comply
with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect
power cables, plugs, sockets and any other connectors for wear or damage. You must ensure that the
risk of electric shock is minimised by the installation of appropriate safety devices. A Residual Current
Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that
a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable
products that are plugged into a supply which is not protected by an RCCB. If in any doubt consult a
qualified electrician. You may obtain a Residual Current Device by contacting your Sealey dealer.
You must also read and understand the following instructions concerning electrical safety.
1.1. The Electricity at Work Act 1989 requires all portable electrical appliances, if used on business
premises, to be tested by a qualified electrician, using a Portable Appliance Tester (PAT), at least once
a year.
1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe
condition of those appliances and the safety of the appliance operators. If in any doubt about
electrical safety, contact a qualified electrician.
1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power
supply. See 1.1.1. and 1.1.2. and use a Portable Appliance Tester.
1.4. Ensure that cables are always protected against short circuit and overload.
1.5. Regularly inspect transformer plug for wear or damage.
1.6. Important: Ensure that the voltage marked on the appliance matches the power supply to be used.
1.7. DO NOT pull the plug from the socket by the cable.
1.8. Use Proper Power Cord. Use only the power cord specified for this product and certified for the
country of use.
1.9. DO NOT connect or disconnect probes or test leads whilst they are connected to a voltage source.
1.10. To avoid fire or shock hazard, observe all ratings and markings on the product. Consult the product
manual for rating information before making connections to the product. To avoid shock hazard,
use a correctly rated probe for your measurement.
1.11. Protect the oscilloscope from electro-magnetic fields, static electricity and high temperatures.
1.12. To avoid fire or shock hazard, observe all ratings and markings on the product. Consult the product
manual for rating information before making connections to the product.
1.13. DO NOT touch exposed connections and components when power is on.
1.14. Connect the probe output to the measurement device before connecting the probe to the circuit
under test. Disconnect the probe input and the probe reference lead from the circuit under test
before disconnecting the probe from the measurement device.
2. GENERAL SAFETY

Familiarise yourself with the applications, limitations, and potential hazards of the oscilloscope.
 Keep the oscilloscope clean and in good condition.

Disconnect circuit power and discharge capacitors before testing resistance, continuity and diodes.
 Remain vigilant when using the oscilloscope on, or near, machinery where there are rotational
parts such as belts, pulleys and fans.
 Remove ill fitting clothing. Remove ties, watches, rings, and other loose jewellery, and contain and/
or tie back long hair.
 Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.

Keep Product Surfaces Clean and Dry.
 DO NOT use the oscilloscope if damage is suspected. If suspected damage occurs with the
device, have it inspected by qualified service personnel before further operations.
 DO NOT get the oscilloscope wet or use in damp or wet locations or areas where there is condensation.
 DO NOT use the oscilloscope for any purpose other than for which it is designed.
 DO NOT allow untrained persons to operate the oscilloscope.
 DO NOT operate the oscilloscope when you are tired or under the influence of alcohol, drugs or
