1.3 At the TC Setup display the user can select the desired t/c from the TC Type list, select the mV to

temperature conversion standard, set the temperature display resolution, select Simulate Mode or enter
the User Re-Calibrate Mode. Arrow Up or Down to the desired menu option and press the Select soft
key.

1.3.1

TC Type – select from T/C types E, J, K, N, T, B, R, C, D, S, M, or P. Use the Up and Down
soft keys and Save key to set type.

1.3.2

Standard – choose from NIST 175 (default), ITS 90 or ITS 68
standards. Use the Up and Down soft keys and Save key to set.

1.3.3

Resolution – use to select temperature display resolution of 1

° or 0.1°. Use the Up and

Down soft keys and Save key to set.

1.3.4

Simulate Mode – select simulate mode to simulate a t/c mV output to a receiving device.
See details below.

1.3.5

User Re-Calibration – select this menu option to calibrate the TIO0110 module with
appropriate local standards. See details below.


2.0 Simulate Mode

Select

Simulate Mode from the TC Setup screen to access the TC simulation display. From this display the user

can select simulation units, start a simple simulation or setup and execute an automated test procedure.














2.1 The

Start menu begins a TC or mV simulation. When Start is selected with the Select soft key, a numeric

entry screen appears to facilitate the entry of the desired simulation temperature value (or mV value).
Once the value has been entered, the MFT will use the previously selected conversion standard to
determine the corresponding mV value and output that value through the TIO mini-t/c connector.

2.2 The

Units menu line is used to select the temperature units for the simulation.

°C, °F, °K, or °R are the

available temperature units. The user can also select mV units for the simulation if desired.

2.3 Step Value is a user entered value that can be used to increment or decrement the simulation value after

the simulation is started.

2.4

Auto-Step x menu options allow pre-programmed simulations to be set up and executed automatically by
the MFT / TIO. Auto-Steps are automatically stored for future use.
