MENU DESCRIPTIONS
RON Relay on set point
Sets the CO2 concentration which the optional relay is energized.
Low limit: 0 PPM
Factory setting: 1000 PPM
High limit: 2000/5000 PPM (depending on model)
ROF Relay off set point
Sets the CO2 concentration which the optional relay is
Low limit: 0 PPM
Factory setting: 950 PPM
High limit: 2000/5000 PPM (depending on model)
DSP Display configuration
Determines the LCD display configuration during normal operation. The LCD display can indicate the CO2 concentration and the temperature, the CO2 concentration only or the temperature only. The factory default is to display both the temperature and the CO2 concentration.
CT CO2 concentration and temperature C CO2 concentration only
T Temperature only
UNI Units selection
Temperature and barometric pressure measurements can be displayed in US engineering units or SI engineering units. The factory default is to display US engineering units.
US units | F for temperature and in Hg for |
| barometeric pressure |
SI units | C for temperature and hPa for |
| barometric pressure |
COL CO2 low output range
Sets the CO2 concentration for the lowest output (4 mA or 0 VDC).
Low limit: 0 PPM
Factory setting: 0 PPM
High limit: 2000/5000 PPM (depending on model)
COH CO2 high output range
Sets the CO2 concentration for the highest output (20 mA, 5 VDC or 10 VDC). When COH is set above COL, the transmitter is direct acting and the output will increase with an increase in CO2 level. When COH is below COL, the transmitter is reverse acting and the output will increase with a decrease in CO2 level.
Low limit: 0 PPM
Factory setting: 2000/5000 PPM (depending on model)
High limit: 2000/5000 PPM (depending on model)
TOL Temperature low output range
Sets the temperature for the lowest output (4 mA or 0 VDC).
Low limit: 32.0°F / 0.0°C
Factory setting: 32.0°F / 0.0°C
High limit: 122.0°F / 50.0°C
TOH Temperature high output range
Sets the temperature for the highest output (20 mA, 5 VDC or 10 VDC). When TOH is set above TOL, the transmitter is direct acting and the output will increase with an increase in temperature. When TOH is below TOL, the transmitter is reverse acting and the output will increase with a decrease intemperature.
Low limit: 32.0°F / 0.0°C
Factory setting: 122.0°F / 50.0°C
High limit: 122.0°F / 50.0°C
BAR Barometric pressure
Sets the typical barometric pressure for the location where the transmitter is mounted. The factory setting is for standard pressure at sea level. Adjusting the barometric pressure gives a more accurate measurement, especially at higher elevations.
Low limit: 20.0 in Hg / 600 hPa
Factory setting: 29.9 in Hg / 1013 hPa
High limit: 32.0 in Hg / 1100 hPa
