 Warning

To prevent possible electrical shock, fire, or personal 
injury:
• Read all safety information before you use the Product.
• Do not alter the Product and use only as specified, or the 

protection supplied by the Product can be compromised.

• Comply with local and national safety codes. Use 

personal protective equipment (approved rubber gloves, 
face protection, and flame-resistant clothes) to prevent 
shock and arc blast injury where hazardous live 
conductors are exposed.

• Use Product-approved measurement category (CAT), 

voltage, and amperage rated accessories (probes, test 
leads, and adapters) for all measurements.

• Do not use test leads if they are damaged. Examine the 

test leads for damaged insulation and measure a known 
voltage.

• Do not use the Product if it is altered or damaged.
• Do not work alone.
• Do not make connections on hazardous live conductors 

in damp or wet environments.

• Do not use the Product around gas or vapor.
• Protect the Product against direct solar radiation.
• De-energize the circuit or wear personal protective 

equipment (PPE) when you remove test leads installed 
outdoors because the insulation properties can be 
compromised by dust and moisture.

• Do not apply or remove test leads on energized circuits 

under wet conditions.

• Do not exceed the Measurement Category (CAT) rating of 

the lowest rated individual component of a Product, 
probe, or accessory.

• Keep fingers behind the finger guards on the probes.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or 

60 V dc.

• Do not apply more than the rated voltage, between the 

terminals or between each terminal and earth ground.

• Measure a known voltage first to make sure that the 

Product operates correctly.

• Do not touch the metal parts of one test lead when the 

other is still connected to hazardous voltage.

• Have an approved technician repair the Product.
• Remove the input signals before you clean the Product.
