HP E1586A Rack Mount Terminal Panel
Measuring Using
the Left, Center, and
Right Thermistors
To measure all three thermistors, select three HP E1413C/E1415A channels
as reference channels. The recommended method is to use thermistor 1, the
left thermistor (HI-T1S and LO-T1S), as a reference for channels 0 - 7 (or
32 - 39), thermistor 2, the center thermistor (HI-T2S and LO-T2S), for
channels 8 - 23 (or 40 - 47), and thermistor 3, the right thermistor (HI-T3S
and LO-T3S), for channels 24 - 31 (or 56 - 63). Connect the reference
channels HI and LO terminals to the respective
Connect the reference channel’s HI and LO terminals to the appropriate
thermistor terminals (e.g., channel 100 HI and LO terminals to thermistor 1
HI-T1S and LO-T1S terminals, respectively). These connections are shown
in Figure 10 on page 15.
If two Terminal Panels are used, each panel must be connected as above so
that both panels provide reference temperature measurements. These
connections are shown in Figure 11 on page 16.
Use the information in the HP E1414C/E1415A User’s manuals to setup the
instruments to make the reference measurements. The following are two
examples that measure type K thermocouples. One example uses a single
Terminal Panel and the other uses two Terminal Panels.
