Part number of OPAMP usd in Hantek IDS01070A

engineer@home

Dear Ma,am Sir,
  I checked the OPAMP and it is OK, and I also checked the HEF4052 and it is not the cause of the Spike.  I discovered the 900K resistor on the defective channel has changed its value, I replaced it  and it is OK now.  However, the gain is LOW. I checked that the Relay of the GOOD channel has pins 3 and 4 is not closed while the relay of the defective channel has pins 3 and 4 closed.  In the relay of the good channel, pins 2 and 3 are closed while the Pins 2 and 3 of the relay of the defective channel are not closed.  The relays I am referring to are the ones connected to the Input or the BNC.  I do not know what happened but I think the Normally open and Normally closed contacts are different for both relays.  The part number of the Relays are PL-4.5 but I cannot find the datasheet.

Can you please tell me the manufacturer part number of the relay with pins 2 and 3 are closed when not energized so I can buy one and replace the relay of my defective IDSO1070A?  Thank you for your attention.

Dear Sir, Ma'am,






After fixing the signal relay the scope is working again.  However, sometimes maybe due to my computer setup, a blue screen of death sometimes happens to my PC.  I solved the problem by plugging the DSO1070A into a USB 3.0 port.  I also downloaded the latest Virtual COM port Driver from ST Microelectronics.  Here is the link for faster Download:

Hello, is there a software update for the IDSO1070 that facilitates the use of the cc65 clamp?

Sorry, there is no.
CC65 has two gears: 1:10 and 1:100, you can use ×10 or ×100 probe coefficient to test.
When calculating, we only need to replace V with A.
