• Using the correct line voltage.
• Using the proper test equipment.
• Using the specified reading limits.
Environmental conditions
Conduct the procedures in a test environment that has:
• An ambient temperature of 18° to 28°C (65° to 82°F).
• A relative humidity of less than 70% unless otherwise noted.

the specified temperature range.
Also, allow the test equipment to warm up for the minimum time specified by the
manufacturer.
