    表面電阻測試儀 Surface Resistance Tester

    2.1.1 參考標準:ANSI/ESD STM11.11-2022, ANSI/ESD STM11.12-2021, ANSI/ESD
    STM11.13-2021,ESD TR53-01-22
    2.1.2 技術要求 Technical requirements 電阻測試儀 Resistance Measurement Apparatus (Refer to ANSI/ESD STM11.11-
    2021, ANSI/ESD STM11.12-2021, ANSI/ESD STM11.13-2021, ESD TR53-01-22)
    儀表應能夠進行從 1.0E+03 ohms 到 1.0E+12 ohms 的測量。
    儀表的電路電壓應為:1.0E+06 ohms 及以上的負載測量時電壓為 100 伏 (±5%)。
    ≥1.0E+04 歐姆到 < 1.0E+06 ohms 測量時電壓為 10 伏 (±5%)。對于 1.0E+03
    ohms 到小于 1.0E+04 ohms 的測量,儀表應具有 10 伏 (±5%) 的開路或負載電壓。
    The meter shall be capable of making measurements from 1.0E+03 ohms to
    1.0E+12 ohms.
    The meter shall have a circuit voltage of :
    100 volts (±5%) while under load for measurements of 1.0E+06 ohms and above.
    10 volt (±5%) while under load for measurements from ≥1.0E+04 ohms to less than
    1.0E+06 ohms.
    The meter shall hane an open circuit or under load voltage of 10 volt (±5%) for
    measurements from 1.0E+03 ohms to less than 1.0E+04 ohms. 兩點間電極 Two-Point Probe (Refer to ANSI/ESD STM11.13-2021)
    兩點間電阻測試探頭為特制探頭,參見圖 6。其主要特征要求為:兩柱狀電極直徑
    為3.2mm ± 0.1mm,電極中心到中心的距離6.4mm,電極材料鍍金且存在在4.3mm±
    0.1 mm 的行程內有 4.7 牛+/-10%的彈簧力。電極接觸端圓柱狀材料導電橡膠長
    3.2mm ± 0.1mm,硬度 60+/-10(邵氏 A 級),其體積電阻小于 500 ohm-cm。
    注:在金屬表面上已 10V 電壓測量時,兩個電極之間的電阻應小于 1.0E+03 歐姆。
    The two-point probe consists of an insulated metal body with a PTFE insulator
    inserted into each end. PTFE is used because of excellent dielectric properties.
    One insulator holds test leads; the other holds receptacles that accept spring loaded pins.One receptacle is surrounded by a cylindrical insulator, which is
    surrounded by a metal shield. The pins are gold-plated and have a spring force of
    4.7 Newton + 10% at a travel of 4.3 mm± 0.1 mm. The pins tips are machined to
    accept friction fitted 3.2 ± 0.1 mm diameter electrically conductive rubber
    electrodes or conductive rubber boots. The rubber has a Shore-A durometer
    hardness of 50-70 Electrode volume resistivity is < 500 ohm-cm. The electrodes
    are spaced 6.4 mm centerto center.
    NOTE: The resistance between two resistance measurement electrodes should be
    verified to be less than 1.0E+03 ohms when measured at 10 volts on a metallic
    surface. 圓柱形電極 Cylindrical Electrodes (Refer to ESD TR53-01-22)
    圓柱形電極,重量為 2.27 kg±2.5%(5 磅±2.5%),直徑為 63.5 mm±5%(2.5 英寸
    ±5%),肖氏(IRHD)硬度介于 50 和 70 之間的導電材料。在金屬表面上測量時,
    兩個電極之間的電阻應小于 1.0E+03 歐姆。
    Cylindrical electrodes with a weight of 2.27 kg ± 2.5% (5 pounds ± 2.5%) and a
    diameter of 63.5 mm ± 5% (2.5 inches ± 5%) having a contact of electrically
    conductive material with a Shore-A (IRHD) durometer hardness between 50 and
    70. The resistance between two electrodes should be less than 1.0E+03 ohms
    when measured on a metallic surface. 儀表分辨率:數顯式,用于符合性驗證的設備要求小數點后 1 位。例如標準電阻為
    1 兆歐,儀器應顯示為 1.0E+06 ohms.
    Instrument resolution: digital display, Equipment used for compliance verification
    requires 1 decimal place. For example, if the standard resistance is 1 megohm, the
    instrument should display as 1.0E+06 Ohms. 儀表精度 Meter accuracy
    精度為±10 %。
    accuracy ± 10%.
