Hi,

I bought this GW Instek GDS-820C digital oscilloscope.
To my surprise it was extremely difficult to use in daylight.
The screen raster was next to impossible to see at 100%
contrast. I subdued afternoon light it was OK but even
when the room was rather dark, the display "disappeared"
at around 40% contrast. Has any one any experience in
this?

In the light level I refer to there was for example no problem
to distinguish the old TDS 220 b/w,  the laptop screen (color)
or the mobile phone (color ). I returned the GDS-820C to
the supplier and ordered another brand instead, but I sort of
liked some of the features it has. Relatively long memory a.o.

Regards,
PerL
