Adjusting Sensor Using Display
The four buttons listed below perform the following functions:
[CLEAR] - Resets Menu / Returns to Normal Mode
•
[MODE] - Toggles to Next Menu Item
•
[ENTER] - Press to Lock Menu
•
• [UP/DOWN] - Increase/Decrease Selection Value
Altitude Correction and ABC Logic™ (ON/
OFF)
1. After 2 minute warm-up period, press [CLEAR] + [MODE]. Hold at
least 5 seconds until the sensor enters the edit mode.
2. The first menu is Altitude Correction. Use the [UP/DOWN] button
to adjust to the proper altitude in 500 ft. increments.
3. Press [ENTER] to lock in value, then press [ MODE] to proceed to
ABC Logic
.
4. Use the [UP/DOWN] button to switch to ON or OFF.
5. Press [ENTER] to lock value then press [MODE] to proceed to
Normal Mode. It is recommended that the ABC Logic feature is left
ON for the best sensor operation.
Selecting a Pre-Programmed Setting:
The pre-programmed settings shown in Table 2 are factory set and
cannot be changed. These settings can be selected from the Standard
Settings (STDSET) menu. The Altitude and ABC Logic features can be
changed without entering the Standard Settings (STDSET) menu.
1. After a 2 minute warmup period, press [CLEAR] + [MODE] and hold
(at least 5 seconds) until the sensor enters the edit mode.
2. Press [MODE] 2 times. You will enter the STDSET menu.
3. Use the [UP/DOWN] button to select the desired pre-programmed
number. See the section "Configuring the Sensor" on page 3, for the
appropriate setting number.
4. Press [ENTER] to lock selection; press [MODE] to return to Normal
Mode.

For Non-Standard (Custom) Settings
The non-standard (custom) settings can be changed at any time after the
sensor is powered up. The seven settings (variables) are:
• PPM Range
• Scale (proportional or exponential)
• Output (V or mA)
• Output Range V
• Output Range mA
• Relay Setpoint
• Relay Hysteresis.
The Altitude and ABC Logic™ features can be changed without entering
into the Non-Standard (NONSTD) menu.
1. After 2 minute warmup period, press [CLEAR] + [ MODE] and hold
(at least 5 seconds) until the sensor enters the edit mode.
2. Press [MODE] 2 times. You will enter the STDSET menu.
3. Use the [UP/DOWN] button to toggle to the NONSTD menu.
4. Press [MODE] to move through the variables. Use the [UP/DOWN]
button to toggle to the desired setting.
5. Press [ENTER] to lock in the selection; press [MODE] for the next
variable.
Adjusting the Sensor with the UIP Program
The UIP 8000 program (Model 2072) is a Windows based interface
program designed to work with Ventostat ventilation controllers. It
allows quick, easy adjustments to the output, elevation, relay setpoint,
hysteresis and can be used with calibration for calibration. This program
is ideal for units without display but can also be used with display. The
UIP accessory package comes with the program and cables for
connecting the sensor to a laptop computer equipped with a serial
communications port. The main UIP screen (easy-to-use-program) is
shown in Figure 10 below.
