This EProg input enables the use of different voltage and current
values as program parameters.
•
Setting the lower value
1. Adjust and set the lowest desired value on the voltage or
current source (Example A: 1 V).
Wait approximately 30 seconds.
2. Assign a lower temperature threshold value to this adjusted
voltage/current value by pressing the appropriate keys on
the digits keypad of the instrument (Example A: 20
°
C) and
set by pressing
.
•
Setting the upper value
:
1. Adjust and set the highest desired value on the voltage or
current source (Example A: 10 V).
Wait approximately 30 seconds.
2. Assign an upper temperature threshold value to this
adjusted voltage/current value by pressing the appropriate
keys on the digits keypad of the instrument
(Example A: 200
°
C) and set by pressing
.
Example B in the diagram illustrates that the end point values are
freely selectable (e.g., 8 mA and 16 mA).
Example out of diagram A:
•
Adjust the voltage source for an output of 7.6 V!
The unit calculates the temperature value from the gradient of the
two specified end points
(7.6 V correspond to a setpoint 152.0 °C).
This value is shown in the standard display
NOTICE:
If this adjustment is not correctly performed at two different points,
the setpoint setting will be incorrect.
