| 不论在评估或量测一般家电、办公室自动化设备或工业用设备上的电源转换、传输效率或功率量测，弹性与人性化的设计使你的使用上得心应手。本系列数字瓦特表具有3个电压文件位，3个电流档位，及9个瓦特文件位，适当的分辨率与zui合理的价位是你*的选择。 |
1. 基本+/- 0.1%的准确度
2. 电压、电流与瓦特皆为true rms 量测
3. 电压及电流具有手动或自动的换文件功能，及自动换文件之频率量测
4. 使用4 1/2位模拟数字转换器为基准，提供高准确度、高分辨率及高稳定度的量测
5. 使用3个多任务的显示器，可依所需来选择，且均可选择所有的量测功能(vrms, arms, vrms, pf, va, var, hz)
6. 具有电压三段、电流三段及瓦特九段的输入档位选择
7. 自动保存关机前之设定状态，开机后自动回复原先设定
8. 输入电流峰值超过档位警告
9. 具有pt与ct比例乘算功能(0.0010 至 1000.0之间)
10. 各显示器皆具有独立的比较器功能设定
11. 具有面板功能设定的储存与唤回功能
12. 具有显示频均功能
13. 显示保留功能
14. 提供标准rs-232c接口
