2) How to set the adjustment sensitivity
In order to stabilize the equipment operation, a particular range is provided for switching on and off in
the ON/OFF control. This range is called “adjustment sensitivity (hysteresis or sensitivity range).”
What is described below is how to set the adjustment sensitivity after the control method is changed to
the ON/OFF control in the bank setting. (Adjustment sensitivity of 1 °C is set at factory shipment.)
For constant value run mode screen:
PV value (present value)
SV value (target value)

Press the ▲ key three times.
Press it, however, twice for TTM-204.
Press MODE key 13 times.
* Adjustment sensitivity is set in this screen.
Use the ▲/▼ key to change the setting.
Then, holding the MODE key pressed for 2 seconds, the screen moves back to the
operating mode screen.
(In about 2 minutes, the screen automatically moves back to the operating mode screen.)
* The sensitivity range for the ON/OFF control is set at 1 °C at factory shipment.
* Setting the ON/OFF control results in displaying no items related to the PID control.
* Holding the MODE key pressed for 2 seconds moves each setting screen to the run mode screen.
* In about 2 minutes, each setting screen (or any setting screen) automatically moves back to the run mode screen.
