4.3. MODEL 6622A BRIDGE WITH T-OPTION
The following procedure is can be automated in using a test sequence BridgeWorks-C Data
Acquisition Software if the 6622A is connected through a 6664B scanner.
4.3.1. Set Up
1. Ensure that the model 6622A is switched on as well as the optional 6664B, and
6634A Resistance Standard, if installed. Open the BridgeWorks Data Acquisition
Software in the computer.
4.3.2. Inputs-Outputs Verification
1. Have the following resistors ready for connection to the 6622A or pre-connected to
scanner channel leads from the optional 6664B scanner as listed below:

Set these standard resistors into the controlled temperature environment and allow time for
them to stabilize.
2. Use the “Test Sequence” function of the “Configuration” menu of the
BridgeWorks-C Data Acquisition Software to measure the resistance ratio of each
resistor pair with the corresponding excitation current and reversal rate listed below.
See the BridgeWorks-C Software User’s Manual for the particulars of running a test
sequence. These measurements can also be made manually. If they are made
manually, allow sufficient time for the measurement to settle and ensure that all
measurements made that are related to a given closure are with in 24 hour of each
other.
