is displayed, it means that an external reference junction compensation has been selected for a temperature of 0.0°C (programmable from -50°C to +100°C).

The reference junction compensation mode can be reprogrammed as indicated in par. 8.5.6. The external reference junction compensation value can be programmed as indicated in par. 8.5.13.2.

9.3.12Scale factor program

The “scale factor” mode is a method to read or to simulate electrical signals values in terms of engineering units.

The example explains the procedure of installing the “scale factor” function for the calibration of a potentiometric recorder with a scale from 0.0 mbar to 400.0 mbar corresponding to the required electrical linear input signal.

•Press <SHIFT> + <PROGRAM X> keys to enter the "Scale Factor" set-up procedure. The display will indicate the low end of the scale eg. in mbar.

LO:

0.0 Prog

•Press one of the <!> or <"> keys if a decimal point shift is required.

•Press the <▲> or <▼> keys to adjust to the required value.

•Press the <ENTER> key to load in the memory the value and to advance the program one step: the display will indicate the full scale value of the technical unit (eg. mbar).

HI: 400.0 Prog

•Press the <▲> or <▼> keys to adjust the full scale value.

•Press the <ENTER> key to load in the memory the value: the display will indicate one of the menu pages as follows:

Type : 0-1000 mV

Type : 0-100 mV

Type : 0-10 V

Type : 1-5 V

Type : 0-400

Type : 4-20 mA

Type : 0-20 mA

•Select, through <▲> or <▼> keys, the required page and

•press the <ENTER> key to memory load the needed parameter. The display will indicate one of the two following pages:

Mode : Linear

Mode : Square
