Remote mode measurements are inaccurate
Bagel’s remote mode uses an ultrasonic sensor to measure distance. Because sound waves generated by the ultrasonic sensor tends to disperse with an angle, Bagel’s display will indicate the distance of the nearest object in the pointed direction. For more accurate measurements, please remove obstacles in the measuring direction. Some other possible reasons for the inaccuracies are that 1. the object is too far away, 2. target is too small or narrow, or 3. target surface is not facing the ultrasonic sensor.
String mode measurement does not return to zero
When the string is retracted too quickly, Bagel’s measurement may not return to zero. In this case, you can simply click the Mode button once to reset your measurement to zero.
Bagel's display won't turn on
It is possible that your Bagel was left powered on and that discharged its battery. Please charge the device using a micro USB cable and try again. It should take 2 to 3 hours to completely charge Bagel.
How far can Bagel measure?
Bagel has a different measurement range for each of the three modes:
1. String mode: 0m – 3m (0 – 9’6″)
2. Wheel mode: 0m – 10m (0 – 32’9″)
3. Remote mode: 30cm – 500cm (1′ – 16’4″)
String mode measurements are inaccurate
String mode accuracy can be influenced by the speed of pull and retraction. Please avoid pulling the string too quickly or completely letting it go in order to ensure maximum accuracy. Pulling the strong no faster than 50 cm/s (20 in/s) and retracting no faster than 10 cm/s (4 in/s) is recommended for accuracy.
Why is my Bagel displaying an exclamation mark(!) in string mode?
Bagel displays an exclamation mark(!) when the string is retracted too quickly. This notifies the user that the string has been retracted at speeds higher than 10m/s and can be inaccurate. The exclamation mark(!) disappears at zero. If your Bagel displays an exclamation mark(!) and is not at zero even when the string has been fully retracted, you can reset to zero by pressing the mode button on Bagel.
How do I make an inside measurement?
To make inside measurements, you can turn on Bagel’s offset mode which will add the device’s diameter to your measurement.
1. Long-press the mode button to enter ‘Settings’
2. Use the wheel to scroll to ‘Offset’ and press the save button to enter
3. Use the wheel to scroll to ‘On’ and press the save button to select
4. Now Bagel will automatically add Bagel’s diameter (8cm) to your measurement so that you can make inside measurements more easily
How accurate is Bagel?
Bagel has a different measurement accuracy for each of the three modes:
1. String mode: ±5mm. This applies to to measurements between 0 – 280cm (0 – 9’2″). Error may be larger for longer lengths
2. Wheel mode: ±0.5%
3. Remote mode: ±0.5% + 1 digit at -10˚C – 60˚C (14˚F – 140˚F)
The time on Bagel does not match the current time
You can set Bagel’s time to match your current time by pairing Bagel once with your Bagel Labs smartphone app. Please follow the steps listed below:
1. Download the Bagel Labs app from Google play or Apple App Store
2. Pair Bagel with your smartphone through the Bagel Labs app
3. Exit the Bagel labs app
4. Reboot the Bagel device
5. Test by saving a measurement and viewing it on Bagel
If the time mismatch persists, repeating steps 2 to 5 can fix Bagel’s real time clock compatibility issue.
Measurements saved on Bagel are displayed in random order
Bagel displays saved measurements in chronological order. Measurements that have been saved before matching Bagel’s time with your current time will have wrong timestamps and cause the measurement list to seem disorderly. You can solve this problem by backing up previous measurements on the Bagel Labs app and deleting them from the device.
How do I use the bubble level?
You can use the included bubble level to ensure that you are holding Bagel in a perfect horizontal or vertical position.
To attach the bubble level tool, first find two holes on the rounded side of Bagel. Then simply insert the bubble level tool’s two protruding parts into the two holes.
You can remove the bubble level tool by pulling it out with a little bit of force.
Which side of the hook should I use?
You can use any of the two sides of the hook for measuring in string mode but the rubber side is better for gripping onto surfaces.
How do I attach the included strap?
You can attach the strap on Bagel’s silicone case using the two holes on the metal belt clip.
