Performance Verification
Model 6485 Instruction Manual
Introduction
Use the procedures in this section to verify that Model 6485 accuracy is within the limits
stated in the instrument’s one-year accuracy specifications. You can perform these verifica-
tion procedures:
•
When you first receive the instrument to make sure that it was not damaged during
shipment.
•
To verify that the unit meets factory specifications.
•
To determine if calibration is required.
•
Follow calibration to make sure it was performed properly.
WARNING
The information in this section is intended only for qualified service
personnel. Do not attempt these procedures unless you are qualified to
do so. Some of these procedures may expose you to hazardous voltages,
which could cause personal injury or death if contacted. Use standard
safety precautions when working with hazardous voltages.
NOTE
If the instrument is still under warranty, and its performance is outside specified
limits, contact your Keithley representative or the factory to determine the cor-
rect course of action.
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 test equipment.
•
Using the specified test signals and reading limits.
Environmental conditions
Conduct your performance verification procedures in a test environment with:
•
An ambient temperature of 65˚ to 82˚F (18˚ to 28˚C).
•
A relative humidity of less than 70% unless otherwise noted.
