• 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. True-rms Thermal Multimeter Safety Information • 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

Safety Information
3
•
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.
