Question How can I extend the delay time on my 2290

The delay time and sample time share the total time (the 4 seconds). This how to change the delay time:
  • Press "SPEC" "38" "ENTER" the screen will show 1023. Type "3839" then "enter". The delay is now set to 3839 ms (it is the maximum),
  • At the same time you should set the sampling time at 0,
  • Press "SPEC" "39" "ENTER". THe screen will show the value, press "0" and "enter".
Once it is done power off and back on again.
