22  Precautions for Safe Testing

TOS8030

3.3.2

For High Voltage Output

The TEST lamp goes on during testing. In this case, the DANGER lamp also lights
up, alerting the operator that high voltages are being output.

Fig. 3-5

Indicators Lit during Testing 

When the DANGER lamp is lit

Do not touch the DUT, test lead, test probe, or any high-volt-
age-charged sections at the periphery of the output terminals.

Contact with any of these areas may result in electric shock.

Never attempt to touch the PVC covering of the alligator clip of a test lead. (The
dielectric strength is inadequate to prevent shock.) 

Fig. 3-6

Test Lead 

Do not leave the tester while it is operating.

A person who operates the tester must remain with it until the test is complete. If he/
she must leave the tester, always turn the POWER switch off.

Do not turn the POWER switch off.

Except in emergencies, do not turn the POWER switch off while output is being
generated.

Lit

During testing, never attempt to touch 
the alligator clip of a test lead.
