input signal drops, result value of the measure will change slow, causes of
turning on or off relay due to thresholds values. The critical situation is slowly
detected, so it is impossible to predict the relay state in that situations.
• If parameter „ AL ” = „ on ”, the relay will be turned on in the critical situations,
even if his parameter “modE” = ”noAC”.
7.3.2. “inPt” menu
This menu presets the measurement input:
“ tYPE " - type of the input / sensor. This parameter can be set to values:
thermocouple type measurement range
” tc K ” -200˚C ÷ +1370˚C
” tc S ” -50 ˚C ÷ +1768˚C
” tc J ”
-210˚C ÷ +1200˚C
” tc t ” -200˚C ÷ +400˚C
” tc n ” -200˚C ÷ +1300˚C
” tc r ”
-50 ˚C ÷ +1768˚C
” tc b ” +250˚C ÷ +1820˚C
” tc E ” -200˚C ÷ +1000˚C
” volt ” The device has additional measurement range (-10÷90mV)
mainly for diagnostics of measurement circuits. Being in
this range, unit displays direct voltage connected to its
input with resolution 0.01mV (without compensation of
cold ends).
”FiLt” - this parameter sets filtration rate. It can be set to values from 0 (no filtration ) to 5
(strongest filtration – time window about 2 sec).
“toFS”
- offset (expressed in 1°C, range ± 99°C.). This parameter allows shifting of
measurement scale, and express value added to calculated (measured) result.
Warning: The offseting of a scale is realised independently of cold ends automatic
compensation.
7.3.3. ”bri” parameter
This parameter allows user to set bright of the LED display, bright can be set to
conventional values from 1 to 8.
