美国HD HALO II 69KV叉形数字式高压电流钳表 （HALO-8281）
产品特点： ▲三种工作模式：真有效值模式（RMS），平均值模式，跟踪模式；自动量程转换 ▲平均值显示，连续锁定在大值 产品应用： ▲用于测量架空线和地下电缆的电流，HALO钳表必须与绝缘杆配合使用 ▲目前市场上大部分高压钳表只能测量带有绝缘皮的导线，而HALO可测量有导线，因为HALO本身绝缘强度足够，不需要导线外皮的绝缘保护 产品技术指标： ▲测量范围：（ACA交流电流） ▲0.1—199.9A（低量程）；199.9—1999A（高量程）0.1A-1999A（自动量程转换） ▲大读数1999A ▲精度：±2%rdg±1dgt ▲分辨率1A ▲高可测量电压：69KV（ACV交流电压） ▲3位半LCD液晶显示 ▲响应时间15秒 ▲精度3% ▲使用温度范围：-18-50℃ ▲存储温度范围：-18-50℃ ▲电源：9V电池供电 ▲电池寿命：连续使用40小时 ▲外部叉头尺寸：140mm×220mm×30mm ▲内部叉头尺寸：70mm×140mm ▲长度：710mm ▲重量：1.26kg 标准配置： 主机：HALO II 壹台 9V电池 壹个 厂商出厂报告壹份 中文操作指南壹份 厂商英文使用手册壹份 软携包1个 选购件： 绝缘操作杆（3米/每节1米）
High Voltage Digital AmmeterThe HALO® is a high voltage digital ammeter for use on power distribution systems designed to take True RMS AC current measurements. Its open-core design allows the user to quickly hook it over a conductor from the end of a hotstick and obtain a current reading in amperes. The HALO can be used to take spot load measurements on a single phase, as well as take readings on all three phases to determine load balance. There are two models, the HALO I and the HALO II. The HALO I has a peak-hold mode so the reading is stored on the display until reset. The HALO II includes the peak-hold mode and also a tracking mode that allows the user to view continuous changes on the display. The unit can be used on any voltage up to 69kV system voltages. It is available with either a hook-style or fork-style sensing head. A hook style sensing head allows for easy connection to overhead lines from the ground or a bucket truck. The fork style sensing head can be used on overhead lines and underground cable, just below the elbow connection. The HALO can be used over insulated cable. However, it cannot be used over shielded cable, such as the concentric neutral. High Voltage Ammeter Features
