To prevent possible electrical shock, fire, or personal injury:

• Use only correct measurement category (CAT), voltage, and amperage

rated probes, test leads, and adapters for the measurement.

• Do not touch voltages > 30 V ac rms, 42 V ac peak, or 60 V dc.

• Carefully read all instructions.

• Hold the Product behind the tactile barrier. See The Clamp Meter, item

.

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

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

• Do not measure current while the test leads are in the input jacks.

• Do not use the Product around explosive gas, vapor, or in damp or wet

environments.

• Limit operation to the specified measurement category, voltage, or

amperage ratings.

• Do not work alone.

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

between each terminal and earth ground.

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

• Replace the batteries when the low battery indicator shows to prevent

incorrect measurements.

• The battery door must be closed and locked before you operate the

Product.

• Measure a known voltage first to make sure that the Product operates

correctly.

• Remove all probes, test leads, and accessories that are not necessary

for the measurement.
