(contd)
DENSITY and REFERENCE DENSITY
• The density value for the 0/4 mA current is defined in the VALUE 0_4 mA function,
(input range 0.0000 to +99999). The appropriate unit is taken from the UNIT
DENSITY function.
• The density value for the 20 mA current is defined in the VALUE 20 mA function,
(input range 0.0000 to +99999). The appropriate unit is taken from the UNIT
DENSITY and UNIT REF. DENSITY function.
Example (for STANDARD measuring mode):
A0004734
m = Initial value (0...20 mA)
n= Lower signal on alarm level: depends on the setting in the function CURRENT SPAN
o= Initial value (4...20 mA): depends on the setting in the function CURRENT SPAN
p = Full scale value (0/4...20 mA): depends on the setting in the function CURRENT SPAN
q = Maximum current value: depends on the setting in the function CURRENT SPAN
r = Failsafe mode (upper signal on alarm level): depends on the setting in the functions CURRENT
SPAN and FAILSAFE MODE
A = Measuring range
TEMPERATURE
• The temperature value for the 0/4 mA current is defined in the VALUE 0_4 mA
function, (input range –99999 to +99999). The appropriate unit is taken from the
UNIT TEMPERATURE function.
• The temperature value for the 20 mA current is defined in the VALUE 20 mA
function, (input range –99999 to +99999). The appropriate unit is taken from the
UNIT TEMPERATURE function.
! Note!
Values with different signs cannot be entered for the 0_4 mA and 20 mA values if
SYMMETRY is the option selected in the MEASURING MODE function, (see Page 54).
The message “INPUT RANGE EXCEEDED” appears on the display.
Example (for STANDARD measuring mode):
A0001223
m = Initial value (0...20 mA)
n= Lower signal on alarm level: depends on the setting in the function CURRENT SPAN
o= Initial value (4...20 mA): depends on the setting in the function CURRENT SPAN
p = Full scale value (0/4...20 mA): depends on the setting in the function CURRENT SPAN
q = Maximum current value: depends on the setting in the function CURRENT SPAN
r = Failsafe mode (upper signal on alarm level): depends on the setting in the functions CURRENT
SPAN and FAILSAFE MODE
