6253 DC Voltage Current Source/Monitor Operation Manual
4.4.2 Operational Principles
4-80
• Voltage range switching is done by A
5
, and voltage measurement, voltage source, and voltage limit
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 errors for 4-wire connection.
• The AD converter employs an integral type AD, and the integration time can be set between 5 s
and 1000 ms.
