PERFORMANCE TEST
This chapter describes the methods for checking whether the 6240B operates in the specified accuracy.
7.1
Measuring Instrument Necessary for Performance Test
For the performance test, use a measuring instrument which meets the specifications shown in Section 8.1,
"Measuring Instrument and Cables Necessary for Calibration" and standard resistors.
The standard resistors must satisfy constant current of 4 A or higher, resistance value of 100 m
and accuracy
of 150 ppm.
7.2
Connections
The connections required for the performance test are the same as shown in Figure 8-1, "Connections for Cal-
ibration" or Figure 8-2, "Connection for Checking 4 A Current Source Measurement."
7.3
Test Method
Execute the performance test under the following conditions in a location free of dust, vibration, noise or
other adverse conditions:
Temperature:
23
5
C
Relative humidity: 70 % or lower
Warm-up
60 minutes or longer
Self-test, display, key, and buzzer tests
