 Application Logs Screen Overview – Blü-Test Application

The Application Logs Screen (different from the “Probe Logs Screen” described in Sect. 4) is where the Blü-Test Application stores the log files that have either been downloaded from a probe (as described in Sect. 4) or saved as live data in the Graphs Screen (as described in Sect. 5).
Saved log files are initially displayed in the “unassigned” area of the Application Logs Screen (Fig 13) until they have been assigned to a specific Site or Location (as described in Sect. 7).
The Application Logs Screen lets you manage the log files that have been downloaded to the application. The three icons to the right of the log allow you to view a graphical representation of the log, edit the logging site, location, or name (Fig 14) or add a photo to the log. The search bar at the top lets you search for specific logs within the application. The “Send” button below the search bar lets you send selected logs as comma-separated values (.csv) files via email. The “Delete” button lets you delete selected logs, while the “Assign” button lets you assign the selected log to a site or location.

Sites Screen Overview – Blü-Test Application

The Blü-Test App uses a two-tiered approach to managing sites and locations. Sites are the main facility or campus, and Locations are the specific rooms or areas within that facility. Sites and Locations can be entered manually or by importing a file. You can also delete sites and locations from the sites and locations screens, along with exporting a comma-separated values (.csv) file of your sites and locations.

Tools Section of the Home Screen – Blü-Test Application

The Tools Section of the Home Screen includes a number of helpful tools for checking the accuracy and operation of sensors. These include:

The Tools screen includes a number of helpful tools for converting temperature to resistance and resistance to temperature for various sensors. These include:

Best Measurement Practices

• Room Sensor measurement is done by holding the Blü-Test probe directly under the sensor enclosure for 3 minutes or until the reading stabilizes. Body heat or breathing on the sensor is a major source of faulty readings, so holding the Blü-Test probe at the button end and standing away from the sensor is the best way to ensure a good measurement. The Probe Clip Hanger accessory (BA/PCH-1) simplifies this by holding the probe for you (Fig. 31).
• Duct sensor measurement is done by drilling a 5/8” (15mm) hole in the duct near the duct sensor to be tested. Insert the Blü-Test probe in the hole so the tip is as close as possible to the duct sensor under test. Hold the Blü-Test probe in place for 2 minutes or until the reading stabilizes. When finished, remove the probe and cover the test hole with duct tape.
• Duct averaging sensor verification is more difficult. Use the probe clip hanger to clip the probe directly to the averaging sensor at 10 or more locations along its length. Leave the probe in place for 2 minutes or until the reading stabilizes.
• Outside air sensor measurement requires that the Blü-Test probe be placed next to the outside air sensor. This may require a ladder or extension pole. Hold the Blü-Test probe in place for 3 minutes or until the reading stabilizes. The Probe Clip Hanger makes this easier by holding the probe for you (Fig. 32).
• Walk-in freezer/cooler measurements require that the probe be placed in or around the product racks and not near the door. Do not let the probe tip touch the rack. The probe will require more time to stabilize due to the larger differential between room temperature and freezer/cooler temperature. Keep the probe in place for 15 to 20 minutes or until the reading stabilizes. The Probe Clip Hanger makes this easier by holding the probe for you (Fig. 33).
• Immersion dry thermowell measurement can be done as long as the thermowell diameter is big enough. Remove the immersion sensor to be tested and place the Blü-Test Probe into the thermowell. Hold the probe in place for 2 minutes or until the reading stabilizes.
• The piercing temperature probe is designed to be used with “Pete’s plugs”. It is also designed to be used when piercing a medium is needed such as in insulation or soil.

Cleaning

TEMPERATURE ONLY UNITS:
The Blü-Test temperature-only units can be cleaned with a damp cloth with an alcohol-based disinfectant or mild soap. A double-ended brush is included to help with cleaning the seams on the body of the probe. Dry with a towel or warm blower after cleaning. The units should not be submerged or placed in a dishwasher.

TEMPERATURE/HUMIDITY UNITS AND DIFFERENTIAL PRESSURE UNITS:
The Blü-Test temperature/humidity and differential pressure units can be cleaned with a damp cloth with an alcohol-based disinfectant or mild soap, but DO NOT get the tip of the temp/humidity probe wet in any way, and do not let liquid enter the ports of the differential pressure unit. A double-ended brush is included to help with cleaning the seams on the body of the probe. Dry with a towel or warm blower after cleaning. The Blü-Test units should not be submerged or placed in a dishwasher. If liquid does infiltrate the probe tip of the temp/humidity unit, remove liquid immediately with a paper towel or cotton swab and dry with a warm blower. If grease infiltrates the probe, the unit may be damaged. Send it back to BAPI for service.

Note: The Piercing Temperature Probe is NSF certified and must be cleaned in a means that is acceptable to your local food inspector and/or regulatory compliance manager.

Storage

Handle the unit with care because dropping or high vibrations could cause the battery to shake loose or the probe support to crack. The Blü-Test unit should be stored in a dry location with ambient temperatures between:
<1 month: -20 to 50°C (-4 to 122°F)
1 to 3 months: -20 to 40°C (-4 to 104°F)
3 to 12 months: -20 to 20°C (-4 to 68°F)

Diagnostics

Possible Problem: The probe will not link up with the Bluetooth display device.

1. Be sure the display device has the Blü-Test App loaded and is Android OS 5.1 or Apple iOS 10 or higher.
2. Be sure the display device and the probe are turned on and close enough to each other (<30ft or 10m open-air).
3. Cycle power to both the probe and the display device.
4. Verify that Bluetooth communication is turned on on your device.
5. For Android devices, location services MUST be enabled for Blü-Test to work correctly. On your Android device, go to Settings, select Location, and make sure Location is on.

Possible Problem: The temperature or humidity is not accurate.

1. Make sure the Blü-Test probe tip is near the reference or field device.
2. Make sure that independent drafts are not affecting the reference or the Blü-Test probe.
3. Allow the Blü-Test probe to acclimate to the air before registering the reading. This may take between 2 to 5 minutes

Possible Problem: The probe will not go into logging mode.

1. Your onboard memory on the probe may be full. To clear the memory, go to the probe settings screen via the dashboard. Tap the “Delete all logs from probe” button to erase log files from the probe.

Possible Problem: Log file is not downloading from the probe.

1. The log file may be very large so give it time to download. A week-long log file can take up to 30 minutes to download from the probe to the application. This is normal behavior.

Possible Problem: iOS smart device cannot mail CSV files.

1. Make sure the standard iOS mail application is enabled on your smart device.

Recalibration

The Blü-Test unit is factory calibrated and comes with a NIST traceable certificate. The certificate is accessible via the Probe Settings screen. You can tap the “View Calibration Certificate” button to view the certificate. The Blü-Test should be re-calibrated once every year as a standard practice. The unit cannot be field calibrated and must be calibrated at the factory, which includes a thorough inspection, cleaning, calibration, and a NIST traceable re-certification.
