Sealey TA303 - Manual

1.1. PERSONAL PRECAUTIONS

When using this analyser, please observe all normal safety rules concerning :
Protection against the dangers of electric current.
Protection of the analyser against misuse.
 Full compliance with safety standards can only be guaranteed if used with the test leads supplied. If necessary, they must be replaced with genuine Sealey
leads with the same electronic ratings. Failure to do so will invalidate the warranty.
 DO NOT use leads if damaged or if the wire is bared in any way.
1.2. GENERAL SAFETY INSTRUCTIONS

Familiarise yourself with the application and limitations of the analyser as well as the potential hazards. IF IN ANY DOUBT CONSULT A QUALIFIED
ELECTRICIAN.
 Before commencing testing, follow instructions below and select the correct input sockets, function and range on the analyser.
 When the analyser is connected to a circuit, do not touch any unused analyser terminals.
 When the magnitude of the value to be measured is unknown beforehand, set the range selector to the highest value available.
 Before rotating the range selector to change functions, disconnect test probes from the circuit under test.
 WARNING! Never perform resistance, transistor, diode or continuity measurements on live circuits.
 Always take care when working with voltages above 35V DC or 25V AC rms. These voltages are considered a shock hazard.
 WARNING! USE EXTREME CAUTION when working with high voltages.
 Always keep fingers behind the probe barriers whilst measuring, and DO NOT use when hands are wet..
 Before attempting to insert transistors for testing, ensure that the test leads have been disconnected.
 Components should not be connected to the transistor socket when taking voltage measurements with the test leads.
 DO NOT test voltages above 600V AC or DC - the circuitry of the analyser will be destroyed.
 WARNING! NEVER connect the analyser to a voltage source / live circuit when the rotary switch is set to any other function apart from Voltage testing.
 ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
 WARNING! Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts.
Other means should be used to ensure that the terminals are not “live”.
 DO NOT use the analyser in a potentially explosive atmosphere or where flammable material is present.
 ONLY operate the analyser when the back cover is in place and fastened securely.
 If any abnormal readings are observed, the analyser must be checked out by an authorised technician.
 ALWAYS turn off the analyser and disconnect the test leads, before opening the back cover to replace the fuse or battery.
 When not in use, store the analyser carefully in a safe, dry, childproof location out of direct sunlight. If storing for a long period of time, remove the battery.
Storage temperature range: -20°C to 60°C.
Note: The warnings, cautions and instructions referred to in this manual cannot cover all possible conditions and situations that may occur. It must be under
stood that common sense and caution are factors which cannot be built into this product, but must be applied by the operator.
