    VTI Instruments Corp. NOTE In a mixed thermocouple system, it is very easy to accidentally mismatch the hardware setup and the software configuration setup. Care is especially warranted, as the resultant errors may not be large enough to obviously indicate a problem, but be significantly larger than the accuracy specification of the instrument.

  • Page 59: Cold Junction Compensation (Cjc)

    www.vtiinstruments.com The measurement range of the EX10xxA in terms of temperature is a function of its input voltage range and the capabilities of the thermocouple sensors themselves. Specifically, the measurement range of the EX10xxA for the standard thermocouple types is the following: Type Min (°C) Max (°C)

    VTI Instruments Corp. CALIBRATION In order to deliver high measurement accuracy over a wide ambient operating temperature range, the EX10xxA provides the ability to perform an instrument self-calibration. During self-calibration, the input signal conditioning paths are disconnected from the input jacks and connected instead to a calibration bus that is driven by an internal calibration source.

  • Page 63: Dynamic Calibration In Rx1032

    www.vtiinstruments.com NOTE Self calibration is not applicable for RX1032 since during factory calibration process each instrument will be calibrated in precise manner and calibrated data gets stored in the instrument memory. The instrument has to be sent to factory to perform subsequent calibration after the initial calibration date is expired.

Each channel is programmable as to whether it is in Wired-OR or Master-Slave mode. When an LXI Trigger Bus channel is configured for Wired-OR mode, exactly one instrument on the bus must provide a bias on the channel.

  • Page 68: Retrieving Data

    VTI Instruments Corp. The amount of scans that can be buffered within the memory is dependent on the number of channels in the scan list and the requested data format. For this reason, very long scan sequences (in terms of count) will benefit from a minimization of the data format, so as to maximize the number of scans that can be stored.

  • Page 69: User-Defined Conversions

    www.vtiinstruments.com DEFINED ONVERSIONS The EX10xxA nominally accepts standard thermocouple types and performs its thermocouple calculations using polynomial coefficients from the NIST ITS-90 Thermocouple Database. In some applications, however, a user may want to override the embedded coefficients with a user-defined coefficient set.

    VTI Instruments Corp. ECTION TRIGGERING VERVIEW The EX10xxA supports a full function trigger model with a separate arm source and trigger source event structure. The trigger model is based on the industry standard SCPI 1999 Trigger Subsystem and is diagramed in Figure 4-2.

  • Page 71: Events

    www.vtiinstruments.com The trigger model is sectioned into five layers: IDLE, INIT, ARM, TRIG, and DEVICE. The EX10xxA reset condition places it in the IDLE state. A trigger initialize command begins the acquisition sequence by transitioning the instrument through the INIT layer into the ARM layer. As this occurs, the reading buffer memory is cleared, and all enabled limit events are reset to their default states.

  • Page 72: Maximizing Measurement Performance

    VTI Instruments Corp. The instrument’s internal system timer generates ticks at the specified timer interval, where each tick represents a unique event. For example, a TRIG event source set to Timer at a timer interval of 0.005 s will generate internal triggers at a rate of 200 Hz.

  • Page 73: Maximum Trigger Rate

    www.vtiinstruments.com If the desired trigger model configuration requires the use of the digital I/O port and/or the trigger bus, it is thus best to configure the ARM source for the required digital event, leaving the TRIG source as Timer. The TRIG source should be changed from Timer only in the situation where triggering is required on a two-stage digital event.
