2-4 Calibration
Calibration considerations
When performing the calibration procedures:
• Make sure that the equipment is properly warmed up and connected to the appropriate
input jacks. Also make sure that the correct input jacks are selected with the INPUTS
switch.
• Make sure the calibrator is in operate before you complete each calibration step.
• Always let the source signal settle before calibrating each point.
• Do not connect test equipment to the Model 2015 through a scanner or other switching
equipment.
• If an error occurs during calibration, the Model 2015 will generate an appropriate error
message. See
Appendix B
for more information.
WARNING
The maximum common-mode voltage (voltage between INPUT LO and
chassis ground) is 500 V peak. Exceeding this value may cause a break-
down in insulation, creating a shock hazard. Some of the procedures in this
section may expose you to dangerous voltages. Use standard safety precau-
tions when such dangerous voltages are encountered to avoid personal
injury caused by electric shock.
CAUTION
Do not exceed 1100V peak between INPUT HI and INPUT LO or 350V
peak between SENSE HI and SENSE LO. Exceeding these values may
result in instrument damage.
