產品特點：
▲三種工作模式：真有效值模式（RMS），平均值模式， 跟蹤模式；自動量程轉換
▲平均值顯示，連續鎖定在大值
產品應用：
▲用于測量架空線和地下電纜的電流，HALO鉗表必須與絕緣桿配合使用
▲目前市場上大部分高壓鉗表只能測量帶有絕緣皮的導線，而HALO可測量有導線，因為HALO本身絕緣強度足夠，不需要導線外皮的絕緣保護
產品技術指標：
▲測量范圍：（ACA交流電流）
▲0.1—199.9A（低量程）；199.9—1999A（高量程）0.1A-1999A（自動量程轉換）

High Voltage Digital Ammeter
The 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.
