1. The offset current when 0 V is applied to all I/O channels. This measurement
is made on a port, 5 seconds after switching a relay.
2. Measured by the Agilent 4156C with the integration time setting 100 PLC
when 0 V is applied to all other paths.
3. The time to settle to within 50 fA of the final value after 10 V is applied.
4. This is guard capacitance for an I/O channel for following conditions. Four
modules are installed in mainframe, and only one I/O channel is connected.
5. For the measurement less than 1000 pF at the frequency 1 kHz to 1 MHz,
using the Agilent 4284A with 3 m cable. After the compensation using the
capacitance compensation algorithm (a function of VXIplug&play driver).
