    6. Measurement Works for insulation resistance are diverse in materials, shapes, electrical characteristics and other parameters. Insulation resistance is measured by various methods suiting these parameters. This chapter describes the measuring terminals of the meter and measuring methods for insulation resistance that are suitable to various works. Functions of and Connecting Measuring Terminals 6.1.1 Functions of measuring terminals The functions of the measuring terminals located on the front panel are described.

  • Page 58: Connecting Measuring Terminals

    Noise that is generated by the measuring cable sometimes hampers stable measurement of high resistance. Use a low-noise shielded-conductor cable meeting the specification of HIOKI as a cable connected between the “INPUT” terminal and sample for stable measurement. As mentioned in 6.1.1 “Functions of measuring terminals,” the “GROUND” terminal is connected to the “OUTPUT”...

Fig. 6.1 Grounding of “OUTPUT” Terminal (2) Grounding “GUARD” terminal The “OUTPUT” terminal or “GUARD” terminal can be connected to the “GROUND” terminal if the sample is not grounded. However, when measurement is made using a holder or a measuring jig of a part or material and by providing a guard, the same potential is obtained between the guard circuit...

  • Page 60: Measuring Parts And Circuits

    (3) “CHARGE” terminal connection Measuring time can be shortened by taking measurement after charging a sample (precharge) in advance when measuring a sample of a large electrostatic capacity such as a capacitor. The meter is equipped with a terminal for charge voltage output (“CHARGE” terminal) for precharging, which is useful in automatic measurement.
  • Page 61 Fig. 6.3 Example of Holder with Guard Fig. 6.4 Principle of guard In measurement using a holder with a guard illustrated in Fig. 6.3 and considering the flow of a current from Terminal A to Terminal B, one channel passes through Sample (Rx), while the other channel flows to Terminal B passing through Insulating Material a (Ra), the holder plate and Insulating Material b (Rb).

  • Page 62: Auto Measurement

    Generally speaking, a guard is provided to a jig or a holder by connecting this guard circuit to the “GUARD” terminal of the meter by making all currents that are not measured to flow a guard circuit. 6.2.2 Auto measurement Auto measurement, in which a jig or a terminal to be measured is automatically changed, facilitates measurement when there are many parts to be measured or there are many points of measurement.
  • Page 63 [Caution] When changing the measuring terminal by a relay while outputting measuring voltage, serially insert a protective resistance to limit the current passing through the contact to not exceed the maximum permissible current of the contact, for protection of the relay contact. Protective resistance value ≥(measuring voltage)/(maximum permissible current) The meter is equipped with a contact check function that checks connection (contact) of the sample and measuring circuit including a jig and other devices to enhance reliability...

  • Page 64: When Measuring Jig Is Not Used

    6.2.3 When measuring jig is not used When making measurement without using a jig or other means, use a measuring lead with a test rod or a measuring lead with an alligator clip as an option and connect it to the part to be measured.

  • Page 65: Measurement Of Circuits

    6.2.4 Measurement of circuits The circuit is a combination of plural parts. Insulation resistance is measured outside of circuits such as between circuits that are mutually insulated and between a circuit and casing. The measuring method and handling of this meter are the same as those used in measurement of insulation resistance of parts.

  • Page 66: Measurement By Electrode For Surface Resistance Measurement

    6.3.2 Measurement by electrode for surface resistance measurement This electrode is used as a measuring terminal by pressing it onto a surface of the sample. It can be used simply when a sample is relatively soft. Strictly speaking, this electrode does not separate volume resistivity strictly. However, in general, surface resistance is lower and can be measured in practice.

  • Page 74 Detection is made by detecting the electrostatic capacity and this function cannot be used with samples whose electrostatic capacity component is small such as pure resistance. The cable length is predetermined because an electrostatic capacity of the measuring cable enters the jig capacity in parallel.

    Plural command messages can be transferred once by linking them using message separators. The input buffer size of the DSM-8104 is 128 bytes and message character strings exceeding 127 characters cannot be accepted. When this limit is exceeded, the entire command will be ignored (skipped) and the MLE (Message Length Error) bit of the error register will be set.

    When changing the interface, temporarily reset to the local mode or turn the power supply on again. Connecting Control Signals and Flow Control The flow of data transmission and reception is controlled in the DSM-8104 by controlling the RTS signal. Control the controller in the Terminal mode by connecting as follows.

  • Page 115: Transmission Data Specification

    When processing a command message that requests a response, be certain to send a next command message after receiving a response. DSM-8104 requires flow control by the RTS and CTS. Make sure to wire RTS and CTS. Please note that flow control cannot be performed even if the RTS and CTS are short-circuited.
