Definition of Symbols:
Caution:RefertoAccompanyingDocuments
Caution: Risk of ElectricShock
DoubleInsulation
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 beforeusage
1. Do not operate in wet or dustyenvironments.
2. Do not operate in presence of combustible orexplosive 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

3
Do not use theflexible current probe before you read
the following instructions.
1. Do not installthe 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 assemblybefore usage. Do not use the flexible
current probe ifanydamage is found.
3. Do not use the flexiblecurrent probe on circuit rated higher
than 600V in installation category III.

III. OPERATING INSTRUCTIONS
NOTE:
Select the correct CLAMP in the SETUP menu. When the current probe is
connected to the power analyzer, power analyzer will automatically detect the range
selected.
NOTE:
Selectthecorrectfrequency(Hz)intheSETUPmenu.
WARNING:
Allthecurrent probes connected tothepower analyzermust beofthesame
model andsamerange. Mixed modelsanddifferentrangesselected will
causeincorrect resultofmeasurement.

NOTE:
Pleasepayspecialattentiontotheflexible current probes(model 3007)
connectedtothepoweranalyzer.
1. Connecttheflexible probearoundtheconductor.
2. Make surethecurrentflowing direction is in consistentwiththe arrow
