Altitude
0 m
The Altitude value allows CO
2
compensation for local atmospheric pressure and
altitude and ensures the highest CO
2
accuracy. Altitude can be changed from 0 to
2550 meters in 50 meter steps using <UP> or <DOWN>. It will take a few moments
to change the setting, then the menu will advance to the next step. Factory default
is 0 m (sea level).

3. ALTITUDE
V Output
0-5 Vdc
The V Output value controls the analog output voltage span if the PCB switch is set
to VOLT. V Output can be set to either 0-5 Vdc or 0-10 Vdc using <UP> or <DOWN>.
This setting has no effect if the PCB switch is set to mA. Factory default is 0-5 Vdc.
<MENU>

4. OUTPUT VOLTAGE SPAN
Output
Direct
The Output value controls the analog output signal direction. Use <UP> or
<DOWN> to change the setting from Direct (4-20 mA, 0-5 Vdc or 0-10 Vdc) to
Reverse (20-4 mA, 5-0 Vdc or 10-0 Vdc) if reverse action is required. Factory
default is Direct.
<MENU>
Press to advance to next menu item
5. OUTPUT SIGNAL DIRECTION
Output
Test OFF
The Output Test value controls the analog output signal for testing purposes.
Use <UP> or <DOWN> to toggle the output signal to OFF (normal operation),
MIN (minimum output) or MAX (maximum output). The actual output signal will
depend on the PCB switch position (mA or VOLT) and the V Output setting (for
voltage operation). Press <MENU> to set it back to OFF and advance. Factory
default is OFF.

The Temp Units setting is used to select °C or °F display of temperature. Use
<UP> or <DOWN> to select. The selection will also control available setpoint
ranges if the setpoint option is installed. Factory default is °C.
Display is used to control what information is displayed on the LCD. The
selections depend on the installed options. Use <UP> or <DOWN> to select
either CO
