Response time t
10 ...90
..............: at 200 mL/min: 300 ms
at 60 mL/min: 1 s
Warm-up phase........................: 4 minutes (to achieve ISO/DIS 11196 accuracy level)
2 minutes (for first measured values)
Zero drift ..................................: Within the specified accuracy, without limitation in time
