EXAMPLES FOR ADJUSTMENTS IN THE CONFIGURATION & PARAMETER LEVELS
1.) The indicator is to be adjusted for an input signal of 1...9 V and a display range
of 0...100 °C.
The following adjustments must be made:
Con1Con2 Con3/4:
x54x x10x
Ê Voltage 0...9 V
2.) A thermocouple type L (0...800°C) is to provide an output current of 4...20 mA. Ü
The following deviations are known: At 50°C the true temperature is 53°C, and at 750°C
the true temperature is only 745°C.
Con1 Con2 Con3/4 :
x00x x101 x1x1
 Current: 4...20 mA OutL = 0 OutH = 800 Display scaled for output signal
3.) Inverting the output signal Ü
For "Split range" operation, an indicator with 0...11 mA input and 20...4 mA output is
required:
Con1 Con2: Con3/4:
x61x x001 xxxx
 Current: 20...4 mA OutL = 11 OutH = 0
4.) Zooming a Pt 100 input range: Ü
A measuring range of 0...150 °C is to provide an output of 4...20 mA.
Con1 Con2: Con3/4:
x20x x001 xxxx
 Pt 100 3-wire
Ü Condition: the indicator must have the current output option: Order no. 9407-300- 0 0 3/4 x 1
