Fluke Scopemeter 99 Series II no Picture
« on: March 19, 2021, 05:55:08 am »
Hello,

i have an Problem with the Fluke 99 Scopemeter.  Whe i switch i on, i can her the buzzer, an on autoset the relais clicking. With an optical interface i get the screen shot from the scope. I dont know how i could start. The Manual i found dosn't macht to my device.

I trid to do some messurment. 

V1= 3,9V
V6 = 2,66V
V3 = 1,38V
V4 = -14,3V
V5 = -15,6V
V2 = -16,9V

I think this is okay? 

When i chance the Contrast, the Voltages on the V1 - V6 are changing

Mario

Hi Mario, you should be able to find the service manual for this via Google. Certainly sounds like the display.

Hi Mario

I am having the same problem as you - I have a dead Fluke 96B. I think 92B, 96B, 99B and 105B scopes have the same service manual but cannot find it online anywhere.

I asked for help elsewhere in the forum, so far no reply:

If I find a manual I will let you have a copy. Please do the same for me, thanks

Peter
