Keithley 2000 Calibration Manual

Environmental conditions
Conduct the calibration procedures in a location that has:
• An ambient temperature of 23°C ±5°C
• A relative humidity of less than 80% unless otherwise noted
Warm-up period
Allow the Model 2000 Multimeter to warm up for at least one hour before performing cali-
bration.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
in the above section) allow extra time for the instrument’s internal temperature to stabilize. Typ-
ically, allow one extra hour to stabilize a unit that is 10°C (18°F) outside the specified tempera-
ture range.
Also, allow the test equipment to warm up for the minimum time specified by the manufac-
turer.
Line power
The Model 2000 Multimeter requires a line voltage of 100V/120V/220V/240V, ±10% and a
line frequency of 45Hz to 66Hz or 360Hz to 440Hz.
