9.3.1
IN - 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.
9.3.2
Parameter 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.
the procedure indicated below.
•
Switch the instrument -ON-
•
Press the <SELECT> key : the display will show one of the following menu pages:

•
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.
