Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 9: Measurement Concepts
Basic readings
With data store and limit tests disabled ( Figure 9-6 A), the Model 6482 displays the selected
measurement function readings (MSR1, MSR2, RATIO, or DELTA); no data storage or limit test is
performed when those two functions are disabled.
Data storage enabled
With data store enabled ( Figure 9-6 B), all readings are stored in the data store buffer as processed
regardless of the selected measurement function before or during storage. The type of recalled
reading, or statistic, depends on the selected measurement function during recall (MSR1, MSR2,
RATIO, or DELTA).
Limit test enabled
With a limit test enabled ( Figure 9-6 C), the selected limit feed (MSR1, MSR2, RATIO, or DELTA) is
used for Limit 3 through Limit 6 tests. Pass or fail (P or F) information is displayed on the front
panel with the readings. If data store is performed with a limit test already enabled, pass or fail
status information is also displayed with the readings during data recall.
