  • Page 26: Flow Of Measurements

    Operation Flow of Measurements Flow of Measurements Follow the steps below when taking DUT measurements with the 16043A/B. 1. Preparation for Measurement Create a device guide and short bar to fit the shape of the DUT to be measured. Also create a short bar that matches the size and shape of the DUT to be measured.

  • Page 27: Preparations For Measurement

    Operation Preparations for Measurement Preparations for Measurement Fabricating the Device Guide The device hole in the device guide determines the position when the DUT or short bar is placed on the electrodes of the contact board. Consequently, measuring with a device hole that does not match the shape of the DUT will prevent proper contact between the DUT and the electrodes and correct measurement will not be accomplished.

  • Page 28: Creating The Short Bar

    Preparations for Measurement Creating the Short Bar Short bars are not furnished with the 16043A/B. Create a short bar that matches the size and shape of the DUT to be measured. The short bar is used to compensate for the same amount of residual short as when the DUT is measured.

  • Page 29: Selecting And Mounting The Contact Board

    To accommodate various sizes and shapes of DUTs, three types of contact boards are optionally available for 16043A and 16043B. While referring to Chapter 2 “Contact Board” on page 23, select a contact board that fits the DUT to be measured. The contact board is mounted in different ways for the 16043A and 16043B.

  • Page 30: Mounting The 16043B Contact Board

    Operation Selecting and Mounting the Contact Board Mounting the 16043B Contact Board Step 1. Remove the screws from the two positions on the upper part of the fixture and remove the device holder block. Figure 3-4 Remove the Device Holder Bolck Step 2.
  • Page 31 Operation Selecting and Mounting the Contact Board CAUTION Do not touch the electrodes with hands or damage them in any way as this could adversely affect the measuring precision and repeatability. Step 3. Tighten the screws to secure the contact board. Step 4.

  • Page 32: Mounting The Device Guide

    Step 1. In the case of the 16043A, move the sliding mechanism all the way back. Step 2. Place the device guide on the contact board and insert the guide pin into the guide hole to align the position.

  • Page 33: Carrying Out Fixture Compensation

    Also, when the 16043A is to be used for load capacity measurement, fixture compensation is necessary to ensure more accurate measurements. For the electrode used for load capacity measurement, take measurements of the data for open compensation and of the data for short compensation.

  • Page 34: Measuring Short Compensation Data

    For normal guard measurement using the 16043A/B, short the electrode's H terminal and the L terminal on the contact board. When measuring load capacity using the 16043A, short the electrode connected to the H terminal and the L terminal on the contact board and make the insulator part contact the G terminal as shown in Figure 3-9.
