To avoid electric shock:
• Use caution during installation and use of this product.
High voltages and currents may be present in circuit under
test.
• This product must be used only by qualified personnel
practising applicable safety precautions.
• Do not use product if damaged.
• Always connect clamp to display device before it is installed
around the conductor.
• Always ensure that the clamp is removed from any live
electrical circuit, and that leads are disconnected before
removing the battery cover.
• Do not hold the clamp anywhere beyond the tactile barrier
see Fig. 1.
