Performance Verification 1-3
Verification test requirements
Be sure that you perform the verification tests:
• Under the proper environmental conditions.
• After the specified warm-up period.
• Using the correct line voltage.
• Using the proper calibration equipment.
• Using the specified reading limits.
Environmental conditions
Conduct your performance verification 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 80% unless otherwise noted.
Warm-up period
Allow the Model 2015 Multimeter to warm up for at least one hour before conducting the ver-
ification procedures.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
above), allow additional time for the instrument’s internal temperature to stabilize. Typically,
allow one extra hour to stabilize a unit that is 10°C (18°F) outside the specified temperature
range.
Also, allow the test equipment to warm up for the minimum time specified by the
manufacturer.
Line power
The Model 2015 Multimeter requires a line voltage of 100V/120V/220V/240V, ±10% and a
line frequency of 45Hz to 66Hz and 360Hz to 440Hz.
