Safety Information
A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and
procedures that can cause damage to the Product or the equipment under test.
XW Warning
To prevent possible electrical shock, fire, or personal injury:
•
Carefully read all instructions.
•
Read all safety information before you use the Product.
•
Use the Product 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.
•
Examine the case before you use the Product. Look for cracks or missing
plastic. Carefully look at the insulation around the terminals.
•
Do not use the Flexible Current Probe if it has damaged insulation, exposed
metal, or if the wear indicator is visible.
•
Do not use test leads if they are damaged. Examine the test leads for damaged
insulation, exposed metal, or if the wear indicator shows. Check test lead
continuity.
•
The battery door must be closed and locked before you operate the Product.
•
Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
•
Use Product-approved measurement category (CAT), voltage, and amperage
rated accessories (probes, test leads, and adapters) for all measurements.
•
Do not exceed the Measurement Category (CAT) rating of the lowest rated
individual component of a Product, probe, or accessory.
•
Measure a known voltage first to make sure that the Product operates correctly.
•
Limit operation to the specified measurement category, voltage, or amperage
ratings.
•
Do not use the Product above its rated frequency.
•
Do not use in CAT III or CAT IV environments without the protective cap installed
on test probe. The protective cap decreases the exposed probe metal to <4 mm.
This decreases the possibility of arc flash from short circuits.
•
Do not apply more than the rated voltage between the terminals or between
each terminal and earth ground.
•
De-energize the circuit or wear personal protective equipment in compliance
with local requirements before you apply or remove the Flexible Current Probe.
