WARNINGS
To ensure the safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.

• Before each use, verify meter operation by measuring a known voltage or current.
• Never use the meter on a circuit with voltages that exceed the category-based rating of this meter.
• Do not use the meter during electrical storms, or in wet weather.
• Do not use the meter or test leads if they appear to be damaged.
• Ensure meter leads are fully seated, and keep fingers away from the metal probe contacts when making measurements.
• Do not open the meter to replace batteries while the probes are connected.
• Use caution when working with voltages above 60V DC, or 25V AC RMS. Such voltages pose a shock hazard.
• To avoid false readings that can lead to electrical shock, replace batteries if a low battery indicator appears.
• Unless measuring voltage or current, shut off and lock out power before measuring resistance or capacitance.
• Always adhere to local and national safety codes. Use individual protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed
