Calibration
•
— Summarizes temperature and relative humidity,
warm-up period, and line power requirements.
•
— Lists considerations to take into account when
calibrating the unit.
•
— States how often the Model 6487 should be calibrated.
•
Recommended calibration equipment
— Lists all equipment necessary for cali-
bration and gives pertinent specifications.
•
— Discusses error messages that might occur during
calibration.
•
— Discusses calibration menu items.
•
— Describes how to halt the calibration procedure at any
time.
•
— Details how to calculate currents from calibrator voltages
and standard resistor values when calibrating the 2nA to 2
μ
A ranges.
•
— Provides step-by-step procedures for calibrating all cur-
rent ranges, as well as all three ranges of the voltage source. The 2nA to 2
μ
A and
20
μ
A to 20mA ranges require separate procedures because of the different calibra-
tion equipment involved.
•
— Describes how to change the calibration code, reset the
calibration code, and view calibration dates and count.
