FNIRSI-138PRO Portable Digital Oscilloscope 2.5MSa/s 200KHz Analog Bandwidth Support AUTO,80Khz PWM And Firmware Update

Compared with the previous product, this oscilloscope is smaller in size and stronger in function. It has upgraded a cbration function, improved the test s, and supports the interface to directly update the firmware.The new version of FNIRSI 138pro can test 800VPP at 10 times the probe, which is equivalent to AC 280V.

Specifications：

Features：

● The oscilloscope has a real-time sampling rate of 2.5MS/s and a 200KHz bandwidth.● With full trigger function (single, normal, automatic),● Works perfectly for both periodic analog signals and aperiodic digital signals.● Voltages up to ±400V can be measured.● Equipped with efficient one-key AUTO, the measured waveform can be displayed without cumbersome adjustment.● The display is equipped with a 2.4-inch high-definition LCD screen with a resolution of 320*240.● Built-in 12mah high-quty lithium battery, a full charge can be used continuously for about 5 hours.

Package includes:

● Type1&2 package include:1 * Oscilloscope● Type 3&4 package include:1 * Oscilloscope1 * 10x Probe

Tips:

▶ The waveform jump up and down when testing the signal and you can just see multiple lines jumpi ng up and down,but can't see the waveform.Solution: Set the trigger mode to “Auto” and then pre the [AUTO] button once.If the problem is not solved,the clip on the probe may not be grounded,or the probe clip end is open circuit. Please use a multimeter to check whether the probe is normal.▶ The left and right jitter of the measured waveform cannot be fixed.Solution: You need to adjust the trigger voltage, the yellow arrow on the right.Pre the up and down keys in trigger mode,The trigger voltage can be adjusted.It is neceary to adjust the yellow indicator arrow to be between the upper and lower waveforms,The waveform is triggered.
