  • Page 16: Guidance On Using The Module

    GUIDANCE ON USING THE MODULE The 40-265-01x strain gauge simulator consists of 6, 4 or 2 bridge networks with a resistance of 350Ω in each arm. One arm is a precise but adjustable resistor, the value of which can be varied ±2% of 350Ω with a resolution of 2mΩ.
  • Page 17 The 40-265 calibration data includes the resistance value at which the bridge is balanced. This will not be precisely 350Ω in the case of 40-265-01x, it could for example be 350.05Ω. If the variable resistor is set to 350.05Ω in this example the bridge is simulating a balanced condition.
  • Page 18 The calibration port is designed so that it can be daisy chained with other resistor modules (for example multiple modules of 40-265). A cable assembly can be purchased as an accessory for this purpose or the user can make their own as shown in Figure 2.3.

  • Page 19: 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 20: 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 37: 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.

    Example: Agilent 34410A or 34411A • A cable assembly to connect the DMM to the 40-265. This can be constructed by the user or the user can purchase a ready made cable from Pickering Interfaces suitable for connecting to the Bridge Connections port.
  • Page 39 Figure 7.2 - 40-265 Soft Front Panel - Used For Verification Procedure Calibration/Adjustment Procedure In normal use the 40-265 does not require regular adjustment however in the unlikely event the module may be returned to the Pickering for re-calibration and rewriting the internal calibration values. Adjustment requires a high performance DMM and an automated program taking measurements from the calibration port in order to maintain its accuracy.
