If anyone is interested, spent this morning calibrating my analyser for Foma 131 and got the following results:-
Enlarger is Vivitar V1 using "Kodak" filter settings from RHD calibration manual
00 : +24 : 195
0 : +20 : 165
1 : +16 : 150
2 : +12 : 135
3 : +8 : 120
4 : -4 : 105
5 : -12 : 90 - grade 5 contrast extrapolated because didn't get dmax
test strips matched by eye against the test card, not by densitometer
