2.2.3
DC Measurement
This section explains basic methods of use, i.e., current measurement using a DC voltage source (VSIM),
the current limiter by changing the source voltage value, and voltage measurement using a current source
(ISVM).
A 1 K
resistor is used as the DUT for the measurement.
Figure 2-7 shows the operating statuses and operating points in DC measurements.

NOTE:
To ensure accurate measurement, use the 6243/44 within the specified temperature range.
Allow the 6243/44 to warm up for at least 60 minutes after the power is turned ON.
In the following example, the warm up stage is assumed to have been completed.
