Safety Information

The Fluke 101 complies with IEC 61010-1 CAT III 600 V measurement category. See General Specifications.
A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that could cause damage to the Product or the equipment under test.

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.

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

• Do not use the Product if it is damaged.

• Disable the Product if it is damaged.
  

• Do not use the Product if it operates incorrectly.

• Examine the case before you use the Product. Look for cracks or missing plastic. Carefully look at the insulation around the terminals.

• Use only correct measurement category (CAT), voltage, and amperage-rated probes, test leads, and adapters for the measurement.

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

• Do not use test leads if they are damaged. Examine the test leads for damaged insulation and measure a known voltage.

• Do not apply more than the rated voltage, between the terminals or between each terminal and earth ground.

• Do not use the HOLD function to measure unknown potentials. When HOLD is turned on, the display does not change when a different potential is measured.

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

• Keep fingers behind the finger guards on the probes.

• Remove all probes, test leads, and accessories before the battery door is opened.
  

• Do not exceed the Measurement Category (CAT) rating of the lowest rated individual component of a Product, probe, or accessory.
  

• Remove the input signals before you clean the Product.
  

• Have an approved technician repair the Product.
  

• Remove the batteries if the Product is not used for an extended period of time, or if stored in temperatures above 50 °C. If the batteries are not removed, battery leakage can damage the Product.
  

• Replace the batteries when the low battery indicator shows to prevent incorrect measurements.
  

• Use only specified replacement parts.
  

• 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.
  

• Connect the common test lead before the live test lead and remove the live test lead before the common test lead.
  

• Do not use in CAT III or CAT IV environments without the protective cap installed. The protective cap decreases the exposed probe metal to <4 mm.
  This decreases the possibility of arc flash from short circuits.
