五. 基本功能使用方法 Operation methods of basic functions
1. 接通仪器电源后，巡回显示三相绕组的温度，同时根据测量结果输出各种控制信号，见表2。
After the instrument is energized, temperature of three-phase windings is displayed in turn. In the meantime, various control signals are output in accordance with measurement results. Please see Table 2.
2. 按键的定义和功能
Definitions & functions of keystrokes
∧：加1键，每按一次，输入参数加1，继续按下时，输入参数连续加1。测量时为巡回显示与最大值显示的转换键。
∧：Adding 1 key. Every time you press this key, the input parameter value adds 1. If you keep the key pressed, the input parameter value will continuously increase by 1. It acts as a switch key between circuit display and maximum value display in time of measurement.
∨：减1键，每按一次，输入参数减1，继续按下时，输入参数连续减1。测量时当三相最大值温度小于C2时，按下此键，手动打开或关闭风机。
∨：Subtracting 1 key. Every time you press this key, the input parameter value subtracts 1. If you keep the key pressed, the input parameter value will continuously decrease by 1. When the highest temperature of three-phase is less than C2 in time of measurement, press this key to manually turn on or turn off the fan.
@：输入转换键，每按一次，进入下一个参数的检查和修改。测量时按下此键，进入监控状态。
@：Input switch key. Every time you press this key, you can enter the examination and modification of next parameter. Press this key to enter into monitoring status in time of measurement.
3. 检查参数的方法（操作流程图）
Methods for parameter examination (See Operation Flowchart)
仪器的基本参数共有8个。提示符分别为C1、C2、C3、C4、Ft、Ht、Ad、Bp。
The instrument has totally 8 basic parameters, with indication symbols being C1, C2, C3, C4, Ft, Ht, Ad and Bp respectively.
C1、C2、C3、C4的定义见表1，Ft为风机定期检测的时间间隔，单位为小时，最大值为250小时，每次开启风机时间约1分钟，若设置为0则无此功能；Ht为所测量三相温度的历史最大值。Ad为通讯地址提示符，Bp为通讯波特率。
Definitions of C1, C2, C3 and C4 are shown in Table 1. Ft represents the interval of periodic examination of the fan, with unit being an hour and the max. value being 250 hours. Time for fan startup is about 1 minute, and the function will not exist if 0 is set. Ht is the max. historical value measured for the three-phase temperature. Ad is an indication symbol of communication address and Bp is communication baud rate.
检查参数的具体方法 Specific methods for examining parameters
仪器通电显示版本号SS03后立即进入测量状态，此时连续按下@键，则按C1、C2、C3、C4、Ft、Ht、Ad、Bp的顺序显示各个参数的设定值。
After the version no. SS03 is displayed following electrification, the instrument immediately enters the measuring state. At this time, press Key @ continuously, the preset values of various parameters will be displayed in the order of C1, C2, C3, C4, Ft, Ht, Ad and Bp.
这些参数值只能检查不能修改。当持续5秒未有键按下，自动回到测量状态。
These parameters can be examined but cannot be modified. If there is no key pressed continuously for 5 seconds, the instrument returns to the measuring state.
4. 修改参数的方法(见操作流程图) Methods for modifying parameters (See Operation flowchart)
当仪器处于测量状态时，按下@键大于15秒钟，仪器I数码管右下角显示小数点，II数码管显示提示符C1，按@键后显示C1的数值，再按∧∨键可以修改C1的数值，按下@键进入下一个提示符C2，再按下@键显示C2的数值，按∧∨键可以修改C2的数值，依此类推……
When the instrument is at the measuring state, hold Key @ for about 15 seconds, a decimal will be displayed at the bottom right corner of the Digital Tube I of the instrument and the indication symbol C1 will be displayed on the Digital Tube II. Value of C1 will be displayed after pressing Key @, and value of C1 can be modified by pressing Key ∧ and ∨. Press Key @to enter the next indication symbol C2. Press Key @again, the instrument will display the value of C2. Press Key ∧ and ∨, value of C2 can be modified, and so on.
5. 手动风机的工作方法 Methods for manually operating the fan
仪器处于测量状态，且温度低于C2时按∨键则打开风机，再按一次则停止风机。
When the instrument is at the measuring state and the temperature is less than C2, press Key ∨ to turn on the fan and press again to turn off it.
6. 选择显示方式 Select display mode
仪器处于测量状态，按下∧键，显示方式在巡回显示和最大值显示之间进行切换，相应的巡回显示指示灯和最大值显示指示灯分别点亮。
When the instrument is at the measuring state, press Key ∧, the display mode will switch between the circuit and max. value modes. And the corresponding MAX. or Circuit light will be on.
