4. Magnifier Band

4. 10KHZ,20KHZ, or40KHZ, it’s up for you to choice.
5. 80KHZ,200KHZ, or300KHZ, it’s up for you to choice.

5. Magnifier adjustment:

There are six position for coarse adjustment, the gain between gears is20±1db; Fine adjustment range>20db.

6. Time window:

7. °～150°
8. 0°～170°
9. These 2 time windows can be used at the same time or separately to be used.

7. Electricity discharge meter

• It is a digit head of form.
• 0–100.0 can be shown by 3½LEDdigit.
• The Error<±5%(counted as full graduation)

8. Ellipse time base

• Frequency is 50HZ,the frequency can bechousedarbitrarily.
• The color of oval display is blue.
• The rotation of oval: each30°as one gear position, it can rotates180°.
• Showing mode: ellipse -- straight line
• The base oval can be adjusted to normal size at high frequency when input voltage (13∽275V), its ingestion power<1V.

9. Testing voltage meter

• Measurement range:100KV(extensible)
• Showing:3½digital voltage meter indication
• Accuracy: better than±5%(counted as full graduation)
