  • Page 15: Guidance On Using The Module

    GUIDANCE ON USING THE MODULE The 41-761 behaves as a precise but adjustable low voltage source, making it ideal for Thermocouple Simulation. As well as Thermocouple Simulation, it can be used for applications that require a reference voltage with fine adjustment, with high accuracy and stability.
  • Page 16 Figure 2.3 - Using The 41-761 Connected Directly To The UUT For Thermocouple Simulation Isolation Switches The 41-761 isolation switches on each channel provide the ability to disconnect the channels from the UUT, providing the benefit of not requiring the removal of cabling when wanting to isolate the UUT.

  • Page 17: Installation

    Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only. PREOPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident.

  • Page 18: Hardware Installation

    For a system comprising more than one chassis, turn ON the last chassis in the system followed by the penultimate, etc, and finally turn ON the external controller or chassis containing the system controller. 9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up sequence.

  • Page 39: Maintenance Information

    For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading.

  • Page 40: Verification & Adjustment Procedure

    SECTION 7 - MAINTENANCE INFORMATION pickering VERIFICATION & ADJUSTMENT PROCEDURE This section provides a procedure for verifying that the 41-761 is performing to specification and guidance on adjustment. In normal use the 41-761 does not require regular adjustment. Where procedures require regular verification checks of instrumentation in a system Pickering Interfaces recommend a 1 year interval between tests.
  • Page 41 ● A DMM with performance at least equivalent to a 6.5 digit model. Example: Keysight 34410A or 34411A ● A cable assembly to connect the DMM to the 41-761. This can be constructed by the user or the user can purchase a ready made cable from Pickering Interfaces suitable for connecting to the front panel connector.

  • Page 42: Verification Test Results

    In the unlikely event that adjustment of the 41-761 is required we recommend returning it to Pickering Interfaces. Adjustment of the 41-761 requires the use of a high performance DMM and an automated program in order to maintain its accuracy in the event of an adjustment being required to improve performance.
