Comments • The HP E1344A, E1347A, E1353A, or E1476A multiplexer is required for
thermocouple measurements. These module’s have built-in thermocouple
compensation circuitry on the terminal module.
• The channel list is of the form (@ccnn), (@ccnn,ccnn), or (@ccnn:ccnn), where
cc = card number and nn = channel number (105 is channel 05 of card number 1,
for example).
• Four-wire temperature measurements use channel pairs. For example, on the HP
E1345A multiplexer, channels 0 and 8, 1 and 9, 2 and 10, etc. are paired. The lower
channel in each pair (0, 1, 2, ...7) is the sense channel. Use channel_list to specify the
"sense" channels.
• You can measure RTD types 85 (alpha = 0.00385 Ω/Ω/°C)
and 92 (alpha = 0.00392 Ω/Ω/°C). The values 385, 0.00385, 392, 0.00392 are
also accepted for the type parameter.
• Thermistor types are 2252, 5000, and 10000. Use thermistors that match the
Omega 440xx series temperature response curves.

Example Making Thermocouple Measurements
CONF:TEMP TC,J,(@100:107) !Measure J-type thermocouples (scan the 8
channels once); trigger source is IMMediate
by default.
READ? !Place multimeter in wait-for-trigger state and
make measurements; send readings to output
buffer.
enter statement !Enter readings into computer.
:VOLTage:AC
CONFigure:VOLTage:AC [<range>[,<resolution>]] [,<channel_list>] selects the
AC-coupled RMS voltage function and allows you to specify the range and
resolution. If you specify a channel list, those multiplexer channels are scanned.
For a complete listing of range and resolution values available, see
Table 5-1 on page 120.
