Warning

These safety warnings are provided to ensure the safety of

personnel and proper operation of the instrument.

·

 Read the instruction manual completely and follow all the safety

information before attempting to use or service this instrument.

·

  Use caution on any circuit: Potentially high voltages and currents

may be present and may pose a shock hazard.

·

 Read the Safety Specifications section prior to using the current

probe. Never exceed the maximum voltage ratings given.

·

  Safety is the responsibility of the operator.

·

  NEVER open the back of the instrument while connected to any

circuit or input.

·

 ALWAYS connect the current probe to the display device before

clamping the probe onto the sample being tested.

·

 ALWAYS inspect the instrument, probe, probe cable, and output

terminals prior to use. Replace any defective parts immediately.

·

 NEVER use the current probe on electrical conductors rated

above 600 V in overvoltage category III (CAT III). Use extreme

caution when clamping around bare conductors or bus bars.

International Electrical  Symbols

This symbol signifies that the probes are protected by double or

reinforced insulation. Use only specified replacement parts

when servicing the instrument.

This symbol signifies CAUTION! and requests that the user refer

to the user manual before using the instrument.

Receiving Your Shipment

Upon receiving your shipment, make sure that the contents are

consistent with the packing list. Notify Omega of any missing items. If

the equipment appears to be damaged, file a claim immediately with

the carrier and notify Omega at once, giving a detailed description of

any damage.
