CLD 780 TR / July 2000 109
SA m,o,f Set analog output mode 4*)
m: mode 0 = 0 ... 1 V
1 = 0 ... 10 V
2 = 0 ... 20 mA
o: offset 0 = 0 %
1 = 20 %
f: Range 0 = 100 %
full-scale 1 = 50 %
SY yy,mm,dd,hh,mm Set date and time 4*)
(year, month, day, hour, minute)
SS n Activate ”Standby“ operation 2,4*)
n: 1 = Standby (ozone generators off)
0 = return to measure mode (i.e. restart
instrument)
2 = Clear instrument error or warning
with highest priority (fatal error pro-
duces a restarting of the CLD 780
TR)
SC i,r,xxxxxx Enter calibration coefficients 2,4*)

Rea. Delay: xxxx [ms] 0020 ... 9999
HC Leave current measurement cycle 4,12*)
HS Start measurement cycle 2,4,12*)
Note: Each measurement cycle must be initiated (i.e. syn-
chronized) using the HS command.
