Agilent / HP 34921T
Terminal Block
Description
This is a Terminal Block for 34921A.
The 34921A/34921T is currently the only multiplexer module for the 34980A that will provide an isothermal reference and temperature sensor for thermocouple measurements on the terminal block.
When this unit is plugged onto the 34921A multiplexer module, the isothermal gradient error is +/- 0.5C due to heat being conducted from the mainframe through the Dsub connector pins into the 34921T terminal block.
Locating the 34921T away from the mainframe using the Y1135A/36A cables where there is no airflow can reduce this error to +/- 0.1C.
A third party external precision isothermal reference panel and sensor will reduce the isothermal gradient error and the reference temperature measurement error.
These panels can be used with the 34921A and the other multiplexer modules for the 34980A.
