When the TUNE program is complete the upper alternating

display stops and only the process temperature is displayed. The PID values are entered automatically. The process temperature will rise to setpoint and control should be stable. If not, this may be because optimum cycle time is not automatically implemented. To set the cycle time see PROPORTIONAL CYCLE-TIME.

The TUNE AT SETPOINT program will now start. The upper display will alternate tune and the process temperature.

The lower display will read the setpoint value.

Note: During tuning the main setpoint (SP1) LED will flash.

REMINDER OF INSTRUMENT ADJUSTMENTS

Press ▲ ▼ together for 3 seconds for program entry or exit. Press ▲ or ▼ to scroll through functions.

Press ✱ ▲ together or ✱ ▼ together to change levels or alter options.

Note: If in difficulty by becoming “lost” in program mode, press ▲ and ▼ together for 3 seconds to return to display mode, check the Menu Navigation summary above and try again.
