FDS138 Mini Digital Oscilloscope 2.5Mhz Sampling rate 200Khz Bandwidth Support AUTO 80Khz PWM for Electronic Repair DIY

Product selling points:

1. Use high-quty materials, durable

2.2.5MHz sample rate, actual bandwidth 200KHz, analog bandwidth 0KHz (sine wave)

3. It has complete trigger function (single, normal, automatic), which can be used freely for both periodic analog signal and non-periodic digital signal

4. The maximum voltage signal of ± 400V can be measured

5. Equipped with efficient one-button AUTO, the measured waveform can be displayed without complicated adjustment

6. It has the function of saving waveform with one key

Upper computer: temporarily not supported

Firmware upgrade: supported

Size: mm wide and 100mm long (excluding BNC head)

Matters needing attention:

1. When measuring voltage above 40V, be sure to shift the probe to X10

2. When measuring high voltage (over 36V AC voltage), do not touch the metal part of the instrument, especially the BNC interface position

3. The charging voltage should not exceed 6.8V to avoid ing the charging chip

4. When the firmware is not upgraded, try to toggle the switch at the lower left corner to Nomal

Part description:

1.2uS and 5uS cannot be used to measure waveforms other than sine wave.

2. Saving the waveform can only save the current display part.

3. Some measured signals cannot be correctly captured with AUTO and need manual adjustment.

4. Firmware upgrade: to upgrade the display part, pre OK to start up, and to upgrade the bottom part, pre SAVE to start up.
