7.3.3. "inPt" menu (common parameters)
This menu presets the measurement input:
type of the input / sensor. This parameter can be set to values:
"0-20" - current input - range 0..20 mA,
"4-20" - current input - range 4..20 mA,
"0-5" - voltage input - range 0..5 V,
"1-5" - voltage input - range 1..5 V,
"0-10" - voltage input - range 0..10 V,
"2-10" - voltage input - range 2..10 V,
"60"
- voltage input - range 0..60 mV,
"75"
- voltage input - range 0..75 mV,
"100" - voltage input - range 0..100 mV,
"tYPE"
"150" - voltage input - range 0..150 mV,
"Pt 1" - Pt 100 input,
"Pt 5" - Pt 500 input,
"Pt10" - Pt 1000 input,
"tc k" - thermocouple input, type K,
"tc S" - thermocouple input, type S,
"tc J" - thermocouple input, type J,
"tc t" - thermocouple input, type T,
"tc n" - thermocouple input, type N,
"tc r" - thermocouple input, type R,
"tc b" - thermocouple input, type B,
"tc E" - thermocouple input, type E.
For current and voltage inputs displayed values are defined by parameters "Lo C","Hi C" (or by user
defined characteristic points) and parameter "Pnt".
- option allows to change the filtration time constant. Expressed in seconds. Acceptable values range from
"FiLt"
0 (no filtration ) to 255.
7.3.4. "inPt" menu (parameters of temperature inputs)
connection method of RTD input. This parameter can be set to values:
connection method of RTD input. This parameter can be set to values:
"4 in" - 4-wire method,
"tYPE"
"3 in" - 3-wire method,
"2 in" - 2-wire method.
- offset expressed in °C, range ± 9.9°C (for RTD input) or ± 99°C (for TC input). This parameter allows shifting of
"toFS"
measurement scale, and express value added to calculated (measured) result.
The offsetting of a scale is realised independently of cold ends automatic compensation.
