1 适用范围

Ø 本SOP适用于Bio-Rad_Power Pac Basic电泳仪的使用与注意事项

2 生效日期

Ø 本SOP文件自2014年5月20日生效，原SOP文件《》停止执行。

3 应用范围

Ø 提供电泳所需的恒定电压或电流。

4 控制面板

4.1 Constant Parameter Key：Selects either constant voltage or current. The LED indicates the selected parameter. During a run, maximum power is indicated when both LED’s are lit.

4.2 Display Mode Key：Selects the parameter to be displayed (volts, milliamperes or minutes). The LED displays the value of the indicated parameter.

4.3 Scroll Keys：Changes the value of the selected parameter. If the Scroll Key is pressed constantly for more than 5 units in either direction, +/-, the values will increase/decrease in increments of 10 to reach the desired value faster.

4.4 Run & Pause Key： Starts and pauses a run. Pausing allows editing of the constant parameter and the parameter values. Corresponding LED indicates the status of the power supply.

4.5 Stop key： Stops run. Constant parameter and limit parameter values are preserved. Timer is reset to zero.

5 使用流程

5.1 打开电源。

Ø The default setting is constant V, and the LED display shows zero value.

Ø To display firmware version number, hold down constant parameter key while turning the power switch to the on position.

5.2 连接电路线。

Ø The power leads are color coordinated to the output terminals in red and black.

Ø Power leads must be inserted perpendicular to the curve of the case.

5.3 选择恒定参数并设定相应的值。

Ø Press the Constant key to select the constant parameter, either voltage or current. The LED on the parameter key corresponding to the selected constant parameter will light up. The display shows the zero value for the constant parameter.

Ø Use the scroll key to enter the desired value. Voltage: 10–300V adjustable in 1V increments. Current: 4–400 mA adjustable in 1 mA increments.

Ø If the scroll key is pressed constantly for more than 5 units in either direction, +/-, the values will increase/decrease in increments of 10 to reach the desired value faster.

5.4 开始运行程序。

Ø Press the run/pause key to start the run. The run LED is lit.

5.5 运行中观察参数。

Ø 在运行状态按Display Mode Key，可观察运行的电压、电流和已运行的时间。

5.6 停止运行，关闭电源。

5.7 按STOP键可停止运行。

Ø 只有在按下STOP键后方可关机，严禁当仪器处在RUN和PAUSE状态时关机。

6 注意事项

Ø 连接电泳槽的电线时注意颜色的匹配，黑色连接线连接黑色插孔，红色连接线连接红色插孔。

Ø 只有在按下STOP键后方可关机，严禁当仪器处在RUN和PAUSE状态时关机。
