Couple of problems arose.

I need 3 test signals:

JIS (3KHz) 1% @ 4Hz
CCIR (3KHz) 1% @ 4Hz (Same as JIS? Am I missing something here?)
DIN (3.15KHz) 1% @ 4Hz

These should, according to the limited service info I have, produce a 1%
reading on the meter for each relevant setting (JIS, CCIR,DIN)

JIS was giving me 0.5% so I read up on the Adobe Audition settings and I
guess i needed mod by 60 hz, (+/-30Hz). That gave me 1% display with JIS
but then doubles up on the CCIR/DIN giving 2%

JIS is supposedly an effective mean reading, CCIR/DIN are Peak, but I'm
not making sense of these readings, any ideas?

Amplitude of the input signal has no effect as long as its large enough
to register.

TIA.

The JIS, CCIR, and DIN are standards set by different countries.

JIA Japan
CCIR Mainly countries of or were of the British Empire
DIN Germany

You probably will not be able to adjust for all 3 countries standars at
once.

This is the Leader LFM-3160, there is a switch for each JIS, CCIR, DIN.
