4.4.7 Calibration Timeout (REG CAL or LONG CAL): Time for the first move in calibration will
be set at a maximum of 30 seconds for REG CAL and all subsequent time outs are keyed
off the time it takes to go from closed to open, to create much shorter subsequent time
outs for smaller valves. The initial 2 minute time out can be lengthened in the Manual
Calibration routine Long CAL.
This should normally be left at REG CAL. If however the valve is likely to take more than
30 seconds to open or close, switching to LONG CAL allows 100 seconds.
The LCD shows “TX FT LO or TX FT HI” press the SEL Key again and the LCD shows “REG
CAL or LONG CAL”. REG CAL or LONG CAL can now be selected.
Pressing the DOWN or UP Key toggles this setting.
