2.2 Hands-on Exercise – Measuring a
Thermocouple
This tutorial is a stepwise procedure for configuring a CR1000 to make a
simple thermocouple measurement and send the resulting data to a PC.
Discussions include programming, real-time data monitoring, collecting data,
and viewing data. Principles discussed are applicable to all CR1000
applications.
2.2.1 Connections to the CR1000
Connect power and RS-232 cables to the CR1000 as illustrated in FIGURE
2.2-1.
Compatible power supplies are discussed in Section 6 Power Supply. When
con
necting power to the CR1000, first remove the green power connector from
the wiring panel. Insert the positive 12 V lead into the terminal labeled “12V”,
and the ground lead into the terminal labeled “G”. Confirm the polarity of the
wires before re-inserting the connector.
Connect the serial cable supplied with the CR1000 between the port labeled
“RS-232” on the CR1000 and the serial (COM) port on the computer. For
computers with USB ports, a USB-to-serial adaptor is required.
