The CORD XL is designed to maximize battery life The power management operates differently depending on the type of communication used Power ON when connected RS232 Communication While connected to your computer and if no Recording is in progress the CORD XL automatically goes to sleep mode if no character is received from the serial port within 2 minutes In that mode it consumes minimum power It will exit sleep mode if you disconnect and reconnect the serial cable from the computer or if you power it OFF then back ON Note that once you established an RS2382 serial connection with the CORD XL the software automatically keeps the CORD XL from going to sleep mode by sending commands every minute Chapter 5 Using the CORD XL Software 14 Bluetooth Communication Bluetooth communication is a low power wireless communication link Once you establish a Bluetooth communication link the CORD XL does not go in sleep mode until you break the communication link To further optimize battery life when not connected two operating modes are available In the first mode the Bluetooth electronics is turned ON for two minutes when the CORD XL is powered ON If you don t establish a Bluetooth connection with your computer during that time the Bluetooth electronics will turn OFF You must then turn the CORD XL OFF and back ON to start a new Bluetooth connection In the second mode in addition to operating

5. S Ges Universal Serial Bus controllers converter is COM2 36 Appendix D Measuring 4 20 mA SIGNALS The CORD XL allows you to record any type of signals as long as those signals can be converted to a DC voltage As 4 20 mA transducers are widely used in instrumentation this section explains how to use the CORD XL to record signals from such transducers 4 20 mA transducers are always specified with a specific operating range the following way the output of the transducer will vary between 4 to 20 mA when its input varies from a minimum to a maximum value Here is an example A 4 20 mA Temperature Transducer will be connected to the CORD XL It is specified to provide an output between 40 C to 100 C 1 As the CORD XL can read only voltages we must first convert the 4 20 mA signal to a voltage signal This is done by inserting a resistor with a known value in series with the 4 20 mA signal The resistor acts as a shunt and by reading the voltage across it we obtain an equivalent reading We recommend the use of a watt 1 5 0 Ohm resistor With such a resistor 20 mA will be converted to 0 100 Volt which is perfect for the 100 mV scale of the CORD XL Other values will also work up to 470 Ohms but you would need to use the CORD XL on the 10 VDC range As it is more than likely that you already have some other instrumentation connected to that 4 20 mA transducer there is probably another resistor inserted in the circuit to
