9.3.1IN - OUT mode selection

Press the <ON> key to power the instrument.

After diagnostic routine, the calibrator will be forced into the “IN” function with the active parameter previously selected (i.e. with the indication of a measured value of +1032 °C with thermocouple type “K”).

In 1032.2°C TcK:

Open input terminals will cause a fluctuation of the reading up to “Underflow “ or “Overflow“ conditions.

To select the simulation mode press the <IN-OUT> key (the indication will be for example, relative to a simulated value of 0 °C for a thermocouple type “K”).

Out 0.0°C TcK:

The output value can be programmed using the two membrane slidewires (<▲> and <> keys).

Keep the key pressed to cause a continuous variation of the simulated value; the speed of variation will change by moving the pressure to the extremity of the keys.

By touching a point, near the two central zones, the value will increase or decrease by one single digit.

Press simultaneously <> and <> cursor slidewires to set the simulated value to zero.

9.3.2Parameter or sensor selection

To select the electrical parameter or the sensor required by the application, in any measuring or simulation mode, follow the procedure indicated below.

Switch the instrument -ON-

Press the <SELECT> key : the display will show one of the following menu pages:

Tc J K T U L N E

Tc R S B C F G D

Pt100 IEC JIS US

ni100 ni120 Ohm

mV V mA Xscaling

Press <▲> or <▼> cursor slidewire to select the appropriate page.

Select the required parameter or sensor, by moving left or right the flashing cursor with keys <!> or <"> (eg. to activate the thermocouple type T choose the page and cursor position as indicated below).

Tc J K T U L N E

Press the <ENTER> key to memory load the selection; the instrument will return to the previous operative mode with the new selected electrical signal or sensor.

By pressing the <SELECT> key, instead of <ENTER>, the instrument will not acknowledge any variation and return to the previous parameter or sensor.
