M.C. MILLER电压表LC-4.5 5203产品介绍
LC-4.5 型是一款手持式电压表，具有多种特殊功能，便于对地下结构进行腐蚀和阴极保护测试。它专为在几乎任何环境条件下进行现场测试而设计。密封的高规格开关、密封的窗口、垫圈外壳和双面均带有防潮防霉涂层的印刷电路板使这一切成为可能。
大型（0.5 英寸）显示字符在高光和低光条件下都易于读取，并且可在很宽的温度范围内工作，对电池的消耗很小。
LC-4.5 建议用于电位测量、侧漏测量、表面电位测量、IR 压降测量、检查整流器的交流和直流电路、检查杂散或危险交流电位以及检查腐蚀阳极。直流电流测量需要使用可选插入式分流器（0-20 安培）。
可选输入电阻功能允许检测外部电路中的高电阻并消除几乎所有情况下产生的错误。
按下保持读数按钮可在任何所需时间冻结显示，这使得仪表可用于具有不同杂散电流的许多区域。它在进行即时关闭和协调测试时也很有用。
包括：
LC-4 便携包（编号 5406）
电线测试导线，红色（编号 33808）
电线测试导线，黑色（编号 34903）
Model LC-4.5 is a hand-held voltmeter to include a number of special features which facilitate corrosion and cathodic protection testing on underground structures. It is designed for field testing under almost any environmental conditions. Sealed Mil-Spec switches, sealed windows, a gasketed case and a printed circuit board with baked-on moisture and fungus resistant coating on both sides make this possible.
The large (0.5 in) display characters are easy to read under both high and low lighting conditions and function over a wide temperature range with very little drain on the battery.
The LC-4.5 is recommended for potential surveys, side drain measurements, surface potential surveys, IR drop measurements, checking both the AC and DC circuits of rectifiers, checking for stray or hazardous AC potentials, and checking galvanic anodes. DC current measurements require the use of an optional plug-in shunt (0-20 Amp).
The selectable input resistance feature permits detection of high resistance in the external circuit and elimination of resulting errors in virtually all cases.
The push-to-hold-reading button freezes the display at any desired time, which makes the meter usable in many areas having varying stray currents. It is also useful when conducting instant-off and coordinated tests.
Includes:
Carrying Case for LC-4 (Item #5406)
Wire Test Lead, Red (Item #33808)
Wire Test Lead, Black (Item #34903)
