The minimum requirements:

• A calibrated vibration meter
• A power source: 12V adapter and/or sufficiently charged battery pack
• Tools (screwdriver/drill) for mounting (1 screw)

The vibration meter comes standard with a battery pack and 12V adapter. In principle, you don't need any additional accessories. While most other systems require an external battery or power supply, this is optional for Frogwatch.

Thanks to the long battery life (2+ months) of the internal battery pack, you can often operate without external power.

In addition to the purchase price, you pay an annual subscription fee for access to the online dashboard (including data usage for the supplied SIM card). The first year is billed at the time of purchase, and after that the subscription renews annually (unless you cancel).

The costs are per system, so it doesn't matter how many users or clients you give access to the online dashboard.

Apart from the dashboard subscription, there are no other mandatory costs. However, we recommend having the equipment calibrated regularly (at least every two years). This can be done through us, but you can also use other service providers.

Yes, you can! Ask about the trial period. You can try all Frogwatch features for a month, including SBR vibration measurements (SBR A and SBR B), alerts, real-time traces, and more. After the trial, we hope to welcome you as a new customer, but there's no obligation.

The measurement axes of Frogwatch automatically adjust so that the z-axis always points most closely in the direction of gravity. The x-axis and y-axis automatically follow, forming a right-handed coordinate system. See our article on Orientation of the Frogwatch Vibration Meter for more information.

During startup, the meter searches for a connection with the Frogwatch Dashboard to retrieve its measurement settings and synchronize the time. Normally this takes no longer than 2 minutes. However, this can take significantly longer if the meter is located in an area with limited mobile coverage.

Check if the meter is on (green LED is blinking) and if there is sufficient mobile coverage at the location. Press the button to force a connection attempt. If the meter still hasn't come online after 30 minutes, please contact our support.

Frogwatch meters periodically connect to the Dashboard to fetch new settings. By default, this happens every 15 minutes. Additionally, the meter will come online immediately if something important happens, such as errors, exceedances, or when a measurement starts or stops. This means it may take up to 15 minutes, unless the start was planned in advance: in that case the meter starts exactly on schedule.

This Sync Interval can be adjusted in the cluster configuration. By not staying online continuously, power is saved to optimize battery life.

Check the configuration to ensure Monitoring is set up correctly. It may be that the previous exceedance was less than the Alarm interval ago, or that the Alert sensitivity is set too high. For more information, see the documentation on monitoring.

Note that a contact person must be added per cluster with a percentage.

It's also possible that the contact is set for a higher percentage or that this contact does not wish to receive email or SMS on that day. This can be configured in the Access menu, under Contacts.

During calibration, the vibration meter is compared by an independent lab with a highly accurate reference sensor. The result is a certificate indicating how much the vibration meter deviates from this reference. This allows you to verify whether the equipment is still functioning properly and accurately.

Note that during calibration, nothing is adjusted or changed on the equipment: it is purely a measurement to determine correct operation and accuracy.

The Frogwatch vibration meter is usually delivered already calibrated, so you can get started right away.

After that, we recommend regular calibration (at least every two years after first use). Why? Apart from the fact that this is often required by (SBR) standards or clients, it also gives you greater confidence in the accuracy of your measurements.

Calibration is a snapshot: suppose the sensor is accidentally damaged and starts giving incorrect values. Although this is unlikely, you might never notice without (re-)calibration. By calibrating regularly, you can be highly confident that your measured vibration values are accurate.

Ultimately, it comes down to a risk assessment: in theory, it would be ideal to calibrate before and after every measurement. But this is usually not practical, so most users choose once a year or every two years.

In principle, one battery pack per meter (included as standard) is sufficient. In practice, many customers opt for a second battery pack per meter. That way, you always have a spare and can quickly swap packs if a project runs longer or move straight to the next project.

The Frogwatch charges automatically when a 12V power supply is connected. If you have extra battery packs you want to charge separately, you can use the separately available Li-ion Charger.

This can be set in two steps:

1. First, add the desired contacts to your project. For each contact, you can choose how (SMS and/or email) and on which days they are reachable.
2. Then, for each cluster, you can specify who should receive notifications. In larger projects, this ensures that only the relevant contacts for that measurement point are alerted.

For more information, see the monitoring chapter of the manual.

Absolutely, notification settings are very flexible. For each cluster, you can set a percentage per contact. For example, you can receive a warning when 75% of the threshold is reached, while other contacts only receive a notification at 100% (or vice versa).

For more information, see the monitoring chapter of the manual.

Frogwatch is a platform for (vibration) measurements around construction sites. If you receive a message from Frogwatch, a contractor or consulting firm has registered you as a contact. This means you will automatically receive an alert if, for example, an unusually high measurement is detected (alarm). For more information, please contact the company mentioned in the message.

If you no longer wish to receive messages or believe they are not intended for you, contact the company mentioned in the message or email us at info@frogwatch.nl. We will stop the messages as soon as possible.

In the Frogwatch dashboard, all measurement data is linked to a measurement point, not a sensor. A measurement point is a specific location where measurements are taken. You give it a descriptive name, such as 'Main Road 1 – Reception'. Then you assign a sensor to this measurement point and can start measuring.

This may sound complicated, but there's a good reason. You can remove the sensor and, after a baseline measurement, reinstall it at the same location (=measurement point) later. It doesn't matter if it's the same sensor: all data for that measurement point appears in the same graph.

Another advantage is that you can fully prepare a future project (create measurement points, set up settings, contacts, and reporting) while the sensors you'll use are still in use elsewhere. When the sensor is placed, you can assign it to the correct measurement point with one click and start the project immediately.

A cluster is a group of measurement points (within the same project) with the same settings. Applying settings at the cluster level saves time when configuring multiple measurement points and ensures consistency. For more background, see the Project Structure chapter in the manual.

The triggered trace function lets you collect and view a few seconds of real-time measurement data around a preset threshold. For example, with a vibration measurement this means 1000 data points per second for each direction (x/y/z). This gives you much more detail than, for example, the SBR A: the peak value + dominant frequency is actually just a brief summary of those 1000 data points.

With a trace, you can view (and export) the entire vibration waveform in detail, not just a single peak value. In addition to the dominant frequency, the frequency analysis (FFT) lets you see exactly how the vibration energy is distributed over different frequencies.

More details can be found in the manual in the Traces chapter.

Absolutely! Frogwatch is designed for measurements according to the SBR A/B/C method, but the definition of threshold values is flexible. If the desired standard isn't listed or you want to use a custom standard, you can add it via the main menu under "Standards". For example, you can define your own SBR A/C weighting curve (characteristic value per frequency, in both velocity and acceleration units) or perform an SBR-B measurement with project-specific A1/A2/A3 values.

Firmware updates will occasionally be available in the Frogwatch Dashboard. These updates may include improvements or new features for the Frogwatch Meter. Go to `Devices`, `Firmware` to see all your devices and their firmware versions. You can choose which meters to update, when, and to which version. If your device is running too far behind, we may ask you to update (or apply it for you) to keep everything running smoothly.

All Frogwatch measurement data is securely stored within the EU on servers hosted by a Dutch company. All data is automatically backed up, so your data is never lost.

Frogwatch is a product of Jitter. Jitter's system administrators can access your data if necessary, but will never share it with third parties. You can also manage who has access to the Frogwatch Dashboard yourself. To do this, go to `Organization`, `Users` in the main menu.
