 G'day list,,,,,,, It's probably not  conclusive, but if  I turn off the
bench lamp, the Marconi TF2700 universal  bridge, works fine ..
Problem was that in process of  checking  some low value  caps , the  desk
lamp using one of those  spiral  Energy Saving Lamps. seems to produce
enough EMR to  upset the  delicate innards of the  xstr bridge.
The caps being tested  all seemed to have inconclusive  results at variance
with the stamped values  and  even gave the  impression they were open or
shorted.
A bit of  low  animal  cunning ( intuition), had me  switch off lamp AND...
all came  good . !---- not just the  once.
Anyone know  about this, or has it  just filtered down here by some  yet to
be determined form of intellectual osmosis  !
Cheers
