Calibration
19-3
Calibration considerations
When performing the calibration procedures:
•
Make sure that the test equipment is properly warmed up and connected to Model 6514
INPUT jack.
•
Always allow the source signal to settle before calibrating each point.
•
Do not connect test equipment to Model 6514 through a scanner or other switching
equipment.
•
If an error occurs during calibration, Model 6514 will generate an appropriate error
message.
WARNING
The maximum common-mode voltage (voltage between common and chas-
sis ground) is 500V peak. DC to 60Hz sine wave. Exceeding this value may
cause a breakdown in insulation, creating a shock hazard.
CAUTION
The maximum input voltage is 250V peak, DC to 60Hz sine wave. Exceed-
ing this voltage may result in instrument damage.
Calibration cycle
Perform calibration at least once a year to ensure the unit meets or exceeds its specifications.
Recommended calibration equipment
Table 19-1 lists the recommended equipment for the calibration procedures. You can use
alternate equipment, but keep in mind that test equipment uncertainty will affect calibration
accuracy. Calibration equipment should have accuracy specifications at least four times better
than corresponding Model 6514 specifications.
