Definition of Symbols:

Caution: Refer to Accompanying Documents

Caution: Risk of Electric Shock

Double Insulation

Over-voltage category III (CAT III):

equipment in fixed installations.

WARNING: If the power analyzer is used in a manner

Not specified by the manufacturer, the protection

Provided by the clamp meter may be impaired.

Please read the following instructions before usage

1. Do not operate in wet or dusty environments.

2. Do not operate in presence of combustible or explosive gas

3. Do not touch exposed metal parts, unused terminals.

4. Consider the use of rubber glove in operation.

5. Do not operate in excess of AC 500V (Phase to Neutral), or

AC 600V (Phase to Phase)

6. Do not operate when the unit seems to be mal-functioning

Do not use the flexible current probe before you read

the following instructions.

1. Do not install the flexible current probe around bare

conductors carrying a voltage from 30V to 600V unless you

are wearing protective clothing and glove suitable for

high-voltage work.

2. Always inspect and check for any damage of the current

probe assembly before usage. Do not use the flexible

current probe if any damage is found.

3. Do not use the flexible current probe on circuit rated higher

than 600V in installation category III.
