DENSITY and REFERENCE DENSITY
• The density value for the start value frequency is defined in the VALUE F LOW
function, (input range 0.0000 to +99999). The appropriate unit is taken from the
UNIT DENSITY and UNIT REF. DENSITY function.
• The density value for the end value frequency is defined in the VALUE F HIGH
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):
A0004735-en
m = Density value and reference density at which a frequency of 0 Hz should be output
(entry in VALUE F LOW function).
n = Density value and reference density at which the frequency, defined in the END
VALUE FREQ. function, should be output (entry in VALUE F HIGH function).
TEMPERATURE
• The temperature value for the 0/4 mA current is defined in the VALUE F LOW
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 F HIGH
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 VALUE F LOW and VALUE F
HIGH 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):
A0004736-en
m = Temperature value at which a frequency of 0 Hz should be output (entry in VALUE
F LOW function).
n = Temperature value at which the frequency, defined in the END VALUE FREQ.
function, should be output (entry in VALUE F HIGH function).
