WatchGas Sustainable preset password is 0000.

3.2.2. SENSOR CALIBRATION

Before the unit can monitor gas correctly, it needs to know the metric. This is done by zero calibration and span calibration.

3.2.3 CALIBRATION ADAPTER

A calibration adapter is used to apply gas to the unit during calibration. Before span calibration, attach the Calibration Adapter over the inlet port on the front of the UNI Sustainable by pressing it into place. Open the gas cylinder valve, then press the Left Key (⬅️) to start the calibration countdown.

After monitoring, remove the Calibration Adapter and complete calibration. Never operate the UNI Sustainable with the Calibration Adapter attached. The UNI Sustainable's sensor operates by diffusion. If the Calibration Adapter is attached during normal operation, inconsistent and lower-than-normal readings will occur because of decreased concentration of the gas being monitored.

Calibration Procedures

3.2.4 ZERO CALIBRATION

Zero calibration sets the baseline for the sensor and is done in fresh air. When the LCD displays ZERO, press the Left Key (⬅️) to start zero calibration. The unit will start a 15-second countdown. After the countdown finishes, the zero calibration result will be displayed on the LCD: PASS or FAIL. If the user does not want to perform zero calibration, during the 15 seconds count, press the Right Key (➡️); ALRT will display, and zero calibration is aborted.

3.2.5 SPAN CALIBRATION

Span calibration sets the metric of the sensor to the gas, using a known concentration gas. When the LCD displays SPAN, apply the known gas to the unit, then press the Left Key (⬅️) to start span calibration. The unit will start a countdown (normally 60 seconds, depending on the sensor). After the countdown finishes, the span calibration result will be displayed: PASS or FAIL. If the user does not want to perform span calibration during countdown, press the Right Key (➡️); ALRT will display, and span calibration is aborted.

3.2.6 BUMP TEST

A bump test checks if the sensor and alarm devices are working properly, using a known concentration gas. When the LCD displays BUMP, apply the known gas to the unit, then press the Left Key (⬅️) to start the bump test. The unit will start a countdown (normally 45 seconds, depending on the sensor). After the countdown finishes, the bump test result will be displayed on the LCD: PASS or FAIL. If the user does not want to perform the bump test during countdown, press the Right Key (➡️); ALRT will display, and the bump test is aborted.

Configuration Settings

3.2.7 CHANGE ALARM LIMIT

All preset alarm limits (High, Low, STEL & TWA) can be changed. When the LCD displays the respective limit (e.g., SET HIGH), press the Left Key (⬅️) to change the corresponding alarm limit. The value change process is similar: the current setting value is displayed with the first digit flashing (e.g., 0000). Use the Left Key (⬅️) to increase the current digit (cycling from 0 to 9). Use the Right Key (➡️) to move the cursor to the next digit. After all digits are done, use the Right Key (➡️) to move the cursor to the OK symbol; press the Left Key (⬅️) to confirm the change.

The UNI Sustainable will show Err if the input data is invalid, such as:

Low alarm setting is bigger than high alarm setting.
High alarm setting is smaller than low alarm setting.
Input data is bigger than the measuring range.

3.2.8 CHANGE BUMP/CAL INTERVAL

The bump and calibration interval can also be changed. When the LCD switches between BUMP INTV and CAL INTV, press the Left Key (⬅️) to change the corresponding interval range. The value change process is similar: the current setting value is displayed with the first digit flashing (e.g., 0000). Use the Left Key (⬅️) to increase the current digit (cycling from 0 to 9). Use the Right Key (➡️) to move the cursor to the next digit. After all digits are done, use the Right Key (➡️) to move the cursor to the OK symbol; press the Left Key (⬅️) to confirm the change.

The UNI Sustainable will show Err if the input data is out of the valid range (0~180 days).

3.2.9 CHANGE SPAN VALUE

The span calibration preset value can also be changed. The change process is similar to changing the alarm limit. However, the new span will not take effect until the user successfully completes a span calibration next time. The UNI Sustainable will show Err if the input data is invalid, such as:

Span setting is smaller than 5% of the measuring range or bigger than the measuring range.
For Oxygen sensor, span setting is bigger than 19.0.

3.2.10 CHANGE DISPLAY UNIT

The UNI Sustainable supports different gas units. To change the gas unit, when the LCD switches between Unit and SET, press the Left Key (⬅️) to change the gas unit. The supported units for the current sensor are displayed on the LCD, with the current selected unit blinking. Use the Right Key (➡️) to change the unit and the Left Key (⬅️) to confirm the selected gas unit.
