    CAUTION Never remove a USB cable from an active Personal Daq device while an acquisition is in progress. An active device is any device that is currently open and has channels configured for scanned input. Such disconnection may require you to exit and then re-launch Personal DaqView, after the USB cable has been connected.

  • Page 15: Connect Channel Signal Inputs

    Connect Channel Signal Inputs CAUTION The discharge of static electricity can damage some electronic components. Semiconductor devices are especially susceptible to ESD damage. You should always handle components carefully, and you should never touch connector pins or circuit components unless you are following ESD guidelines in an appropriate ESD controlled area.

  • Page 16: Start Personal Daqview

    Connecting Thermocouple Wires Thermocouple wires are to be connected in differential mode only. In Personal Daq applications, thermocouples should not be connected single-ended. Doing so can result in noise and false readings. This is especially true when acquiring other high- amplitude signals in conjunction with thermocouple signals that are connected single-ended.

  • Page 17: Configure System

    Configure System This step pertains to configuration of channels and acquisition parameters through Personal DaqView software. To configure a set of parameters, use the appropriate toolbar button (or the View pull-down menu) to open the applicable window. Clicking on the Configure Channel Settings button (9) brings up the Channel Configuration Window.

  • Page 18: Channel Configuration

    Channel Configuration The Channel Configuration Window first opens with the Analog Input screen selected. You can change from one configuration screen to another by selecting the appropriate tab.

  • Page 24: Theory Of Operation

    Theory of Operation Universal Serial Bus (USB) The Universal Serial Bus is ideal for data acquisition applications. Since USB ports (located on the PC) provide power, only one cable is needed to link an acquisition device to the PC. In addition, USB’s high-speed data transfer (from the data acquisition device to the PC) allows for real-time display of acquired data while eliminating the need for additional memory in the acquisition device.

  • Page 25: Optical Isolation

    Optical Isolation The Personal Daq is optically isolated from its host PC by up to 500 VDC. This means that an inadvertent application of such voltage to Personal Daq will not affect the PC. In addition to optical isolation, Personal Daq maintains all sensitive acquisition-related circuitry external to the PC.

  • Page 26: Analog Input Configuration

    Analog Input Configuration Personal Daq/54 and Personal Daq/55 each include 10 analog signal inputs which may be used as 10 single-ended inputs, 5 differential inputs, or as a combination of single-ended and differential inputs with up to 10 connections. Personal Daq/56 includes 20 analog signal inputs which may be used as 20 single- ended inputs, 10 differential inputs, or as a combination of single-ended and differential inputs with up to 20 connections.
  • Page 27 At a measurement duration of 610 milliseconds, the last two bits are considered unreliable, resulting in a resolution of 22 bits. At a very fast measurement duration (12.5 milliseconds), the nine most least significant bits are unreliable, resulting in 15 bit accuracy. Speed vs.

  • Page 28: Automatic Calibration

    Automatic Calibration The Personal Daq module contains a built-in source for performing automatic self-calibrations. These calibrations can be performed between scans periodically throughout the measurement process, as indicated in the following figure. Such calibration ensures accurate measurements, even in environments that experience significant temperature fluctuations.

  • Page 29: Frequency Measurements

    Frequency Measurements (Not applicable to Personal Daq/54) Each frequency/pulse input channel can measure from DC to 1 MHz, offering pulse count (totalize), frequency, and duty cycle type readings. The input voltage range is -15 to +15 VDC absolute maximum. TTL sense levels, Schmitt-trigger inputs <1.3 V (low), >3.8 V (high). Note that each frequency channel can measure pulses that are due to closures of a contact between the input terminal and the Lo terminal.

  • Page 51 Engineering Units Conversion Using mx + b Most of our data acquisition products allow the user to convert a raw signal input (for example, one that is in volts) to a value that is in engineering units (for example, pressure in psi). The products accomplish this by allowing the user to enter scale and offset numbers for each input channel, using the software associated with the product.
  • Page 52 Example 2: A Personal Daq user knows that a linear relationship exists between the voltage output at "Point A" and the voltage output at "Point B" in a certain electrical device. The linear relationship is constant. The user wants to monitor the voltage at "Point B," however; it is inconvenient to connect signal lines in that section of the apparatus.

    • The pre-trigger scan count specifies the number of scans that are to be collected before the trigger point. If the pre-trigger scan count is greater than zero, the system will continuously collect data until the trigger is satisfied. If no pre-trigger scans are required, the system sits idle until the trigger; then, it collects the post-trigger scans before it disarms.

  • Page 105: Analog Filtering

    Analog Filtering A filter is an analog circuit element that attenuates an incoming signal according to its frequency. A low- pass filter attenuates frequencies above the cutoff frequency. Conversely, a high-pass filter attenuates frequencies below the cutoff. As frequency increases beyond the cutoff point, the attenuation of a single- pole, low-pass filter increases slowly.
