6240B DC Voltage Current Source/Monitor Operation Manual
5.4.2 Operational Principles
5-76
• Voltage range switching is done by A
5
, and voltage measurement, voltage source, and voltage lim-
iter always take place in the same range.
•The A
5
and A
6
amplifiers have high input impedance to minimize leakage.
•The A
7
amplifier also has high input impedance to reduce error for 4-wire connection.
• The AD converter employs an integral type AD, and the integration time can be set between 100 s
and 200 ms.
