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 de-energized. Setting value lower than RON provides direct action for detecting high concentrations of CO2. Setting value higher than RON provides indirect action for detecting low concentrations of CO2. U or V on the LCD display will be lit to indicate when the relay is energized.

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
