Description

Temperature Measurements

High-integrity voltage meas-

urements are possible with

three-wire high, low, and guard

switching. In addition to making

two-wire resistance and precision

four-wire resistance measure-

ments, you can make up to

64 channels of thermocouple

temperature measurements

with automatic cold junction

compensation.

The Agilent E1476A High-Density

Reed Relay Multiplexer is a

C-size, 1-slot, register-based

VXI module. This low-offset,

thermocouple compensated

multiplexer is dynamically

conﬁgurable providing 64 chan-

nels of two-, three- or four-wire

(32 channels) of switching. This

multiplexer module consists of

a component card with switches

and a QUIC spring clamp termi-

nal block that plugs onto the

component card. The E1476A is

ideal for applications needing a

relay multiplexer that is dynami-

cally conﬁgurable, and makes

maximum high-quality, high-point

count measurements.

The reference thermistor is also

accessible by both banks, each

bank having a control switch

allowing for either a two-wire or

four-wire resistance measure-

ment of the 5000 Ω reference

thermistor mounted on the

isothermal plane located in the

terminal block. Using a scanning

multimeter conﬁguration, the

channel relays and ﬁve control

relays are programmed by SCPI

commands or by register read/

writes. SCPI command syntax

to make a temperature scan

of K type thermocouples is:

MEAS:TEMP? TC, K, (@100:163)
