共立3125绝缘电阻仪使用说明注意事项
共立3125绝缘电阻仪使用说明注意事项一、注意事项：1.仪器使用前请查看仪器是否完好，是否有损坏或松动的零件，以及是否有明显的污垢，如果发现有问题，应立即停止使用。
2.仪器应放置在干燥、无腐蚀性气体和有一定通风的地方，避免阳光直射或有潮湿的地方。
3.使用前请确保绝缘电阻仪与被测试设备处于零电位状态，以防止可能出现的电击伤害。
4.在使用绝缘电阻仪前，请先熟悉仪器的结构和功能，并按照正确的操作步骤进行操作，避免操作错误导致的故障和危险。
5.进行测量时，请确保被测试设备的电源已断开，并检查附近是否有可能产生电磁干扰的设备，并将其关闭或远离。
6.每次使用后，请及时清洁仪器，用干燥的软布擦拭仪器表面，切勿用水或化学溶剂清洗。
7.仪器长时间不使用时，请按照说明书的要求进行存储，以防止仪器老化或损坏。
二、使用说明：1.打开仪器，在仪器面板上选择所需的电阻测量范围和电压（通常为500V或1000V）。
2.连接仪器的测试线，将一个测试线连接到仪器的"HI"插口，另一个测试线连接到仪器的"LO"插口。
3.将"HI"测试线连接到被测试设备的绝缘部分，将"LO"测试线连接到被测试设备的接地部分，确保连接稳固。
4.按下仪器面板上的"TEST"按钮，仪器将进行电阻测量，在测量过程中仪器会显示电阻值。
5.测量完成后，仪器将自动断开电源，并显示最终的测量结果。
请及时记录测量结果。
6.使用完毕后，请关闭电源，将仪器放置在干燥通风的地方。
三、维护保养：1.定期检查仪器的电源线是否损坏，如有损坏请及时更换。
3.定期清洁仪器的表面和连接线，确保仪器在正常使用条件下工作。
4.仪器长时间不使用时，应存放在干燥通风的地方，同时避免阳光直射。
总之，正确使用和保养共立3125绝缘电阻仪能有效延长其使用寿命，并确保测量结果的准确性。
如果发现任何故障或异常情况，请立即停止使用，并通过合适的渠道进行维修或更换。

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The THS3122 and THS3125 may incorporate a PowerPAD on the underside of the chip. This acts as a heatsink and must be connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature which could permanently damage the device. See TI Technical Brief SLMA002 for more information about utilizing the PowerPAD thermally enhanced package.

Each switch is disabled when the associated output-enable (OE) input is high.This device is fully specified for partial-power-down applications using I off . The I off feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.ORDERING INFORMATIONT APACKAGE †ORDERABLE PART NUMBER TOP-SIDE MARKING QFN − RGY Tape and reel SN74CBTLV3125RGYR CL125Tube SN74CBTLV3125D SOIC − DTape and reel SN74CBTLV3125DR CBTLV3125°°SOP − NSTape and reel SN74CBTLV3125NSR CBTLV3125−40C to 85CSSOP (QSOP) − DBQ Tape and reel SN74CBTLV3125DBQR CL125TSSOP − PW Tape and reel SN74CBTLV3125PWR CL125TVSOP − DGVTape and reelSN74CBTLV3125DGVRCL125†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at /sc/package.Copyright 2003, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.SN74CBTLV3125LOWĆVOLTAGE QUADRUPLE FET BUS SWITCHSCDS037J − DECEMBER 1997 − REVISED OCTOBER 2003FUNCTION TABLE(each bus switch)INPUTOEFUNCTIONL A port = B portH Disconnectlogic diagram (positive logic)1A1OESW1B2A2OESW2B3A3OESW3B4A 4OESW4B 2154369101213811Pin numbers shown are for the D, DGV, NS, PW, and RGY packages.simplified schematic, each FET switchA(OE)BSN74CBTLV3125LOWĆVOLTAGE QUADRUPLE FET BUS SWITCHSCDS037J − DECEMBER 1997 − REVISED OCTOBER 2003 absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†Supply voltage range, V CC−0.5 V to 4.6 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Input voltage range, V I (see Note 1) −0.5 V to 4.6 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Continuous channel current 128 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Input clamp current, I IK(V I/O< 0) −50 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Package thermal impedance, θJA(see Note 2):D package 86°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):DBQ package 90°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):DGV package 127°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):NS package 76°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):PW package 113°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 3):RGY package 47°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Storage temperature range, T stg −65°C to 150°C. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

IEC 61010-1(CAT.III 600V 污染度 2) IEC 61010-031(手持式探针要求标准) ● 自动放电功能：测试电容性负荷的绝缘电阻时，测量后自动释放充电电荷。放电状态可在电压模式中确认。 ● 背光功能便于在阴暗光线或夜间工作。 ● 条形图显示测量结果。 ● 带电线路警告标志和蜂鸣警告。 ● 自动关机功能：为避免忘记关机造成的电池浪费，测量后 10 分钟无操作时仪器将自动关机。 ● 设定测试时间功能：在指定时间里自动执行测量。 ● PI 测量（极化指数测量）：
-4-
注意：必须关闭断路器。 (5) 仪器配备自动放电功能。测量完成后，请勿取下测试线，放开测试开关，让仪器自动释放测试时产生的电压。此时，请确认
电压监视器上的显示是“0V”。 危险
* 测试以后请勿立刻触摸电路。存储的电荷可能导致触电事故。 * 请勿立刻取下测试线，必须等放电完成后再碰触被测回路。 <自动放电功能>` 是测量完成后自动释放充电电荷的功能。放电状态可在电压监视器中确认。放电完成前，移开测试线 2 秒以上，可解除放电 功能。 (6) 切换到“OFF”位置，取下测试线。 （注意） “OFF”以外的量程，不测量时仍需消耗 25mA 的电流(自动关机约 1µA)。 不使用仪器时，请切换到“OFF”位置。（自动关机功能 请参考 6-9） 绝缘电阻的测量原理 电阻（绝缘电阻）上施加一定高电压，获得流动电流值后可计算电阻值。
警告 ● 若仪器出现异常请停止使用。例如：仪器破损或裸露出金属部分。 ● 测试导线连接被测回路时，不要旋转功能选择开关。 ● 请勿对仪器安装替代部件或进行任何未授权的改造，维修时仪器返回共立产品
中国办事处。 ● 仪器在潮湿状态下请勿更换电池。 ● 确定所有测试导线与仪表的测试端口连接牢固。 ● 打开电池盖时，确保仪器已关机。
6-1 断电确认（电压测量） 危险
˔ 为避免触电事故，请勿在对地电压 AC/DC 大于 600V 的回路中测量。即使线间 电压在 600V 以下，对地电压高于 600V 也不能测量。
˔ 测量大电流电力线的电压时，必须在断路器的次级回路中测量，否则可能导致人身伤害事 故。
˔ 电压测量时请注意避免测试线金属部分和回路的短路，可能导致触电事故。 ˔ 电池盖打开时，请不要进行测量。

将电压量程开关设置到“AC.V”位置可测量电压。测量时，无须按测试按钮。 仪器装备有 AC/DC 自检电路，测量直流电压。 直流电压测量中，测试线（红）为正电压时，显示“+”标志。 必须关闭断路器。 (1) 接地线（黑）连接被测回路的接地端，测试线（红）连接测试端口。 (2) 确认液晶屏上电压显示为“0V”。 若不是“0V”标志，则被测回路中存在电压。请再次检查被测回路中的断路器是否关闭。
* 绝缘阻抗测试期间可能发出哔哔声，并非故障。 * 测量电容的负需花时间。 * 绝缘电阻测量时，测试端口电压从接地端正极(+)到测试端负极(-)输出。测量时，接地测试线连接接地端，一般来说，对地的绝
