FAQ
Still something unclear? We'll be happy to answer the most important questions.
01 What can I measure with the Aufmaster?
The Aufmaster can measure any cable with a cross-section of 0.25 to 16 mm² and at least two metallic conductors. Fiber optic cable is therefore not possible.
02 What IP protection class does the Aufmaster have?
The Aufmaster has a protection class of IP54. This means it has complete protection against accidental contact and is protected from splashing water on all sides.
03 How many cores do I need for a measurement result?
The Aufmaster must always be connected with two wires from the cable. Accordingly, it can not measure pure single-wire cables.
04 Which cross sections can be connected?
The Aufmaster can handle cable cross-sections between 0.25 and 16 mm² without any problems. The clamps supplied as standard are suitable for cross-sections up to 4 mm². However, these can be independently replaced with larger clamps at any time.
05 How does the Aufmaster know the characteristics of the connected cable?
At Aufmaster, we maintain a gigantic cable database that grows daily. So chances are huge you can just plug the Aufmaster to the cable, scan or search for the cable in the Aufmaster app, and get started right away.
06 What about cables that are not yet in the Aufmaster cable database?
You simply create new cable types yourself in the Aufmaster app and measure them with a reference piece of the new cable (it must be at least 20 m (65 ft) long). Afterwards you can use the new cable type freely in the Aufmaster App, just like all other cable types. We show how this works in this video.
07 How long does the battery last and how long does it take to charge?
The battery of the Aufmaster is fully charged within 2 hours and lasts up to two weeks on construction sites.
08 Can the battery be replaced?
No. The battery is completely encapsulated with protective dimensions due to the IP54 device protection class.
09 Can I change the WAGO connection clamps?
Of course, you can. You can replace our standard WAGO connection clamps (go up to 4 mm²) with your favorite ones at any time. You can also connect test probes. The only important thing is that the connecting cable on the Aufmaster is not unnecessarily extended.
10 Is the Aufmaster gauged?
No, the Aufmaster is not gauged.
11 What are the eight colors for?
The eight colors are used for easy identification in the Aufmaster app and on the construction site as soon as several Aufmasters are in use at the same time.
12 How is the Aufmaster connected to the smartphone or tablet?
The connection between Aufmaster and Android smartphone or tablet is made via Bluetooth.
13 Can I use multiple Aufmasters at the same time with my smartphone?
Yes, you can. The number of connected Bluetooth devices is defined and varies by the smartphone manufacturer. We do not directly limit the maximum number of connected Aufmasters in the Aufmaster app. However, we recommend not to use more than 5-8 Aufmasters at the same time in order not to overload the Android device's performance.
14 Do I have to stay close by with my smartphone?
The connection between Aufmaster and smartphone or tablet is established via Bluetooth Low Energy. In the open field, you have a stable connection within a radius of at least 35m. Indoors, the range is 15 - 30m. It can decrease depending on the environment due to walls, metal shelves, machines, etc. If the connection is lost, an audible signal is emitted by your Android device that cannot be overheard.
The Aufmaster then stores all measurement data on an internal memory for up to 10 minutes and retransmits them as soon as the Android device is reconnected to the Aufmaster.
15 Does the Aufmaster track my GPS position?
The Aufmaster does not have a built-in GPS module. However, once a cable reel has been successfully commissioned, the Aufmaster app saves the current location of the cable reel (GPS data from the smartphone). Provided that authorization has been granted in the Aufmaster app.
16 Does the Aufmaster work without an app?
No, the Aufmaster must always be used in conjunction with the Aufmaster app. You can download the Aufmaster app for free from the Google Play Store. It is not possible to use without the Aufmaster App.
17 How is the Aufmaster attached to the cable drum?
We have equipped the Aufmaster with two screw holes. So you can easily fix it to the drum with two matching screws. If the Aufmaster is connected to a cable ring, it is best to place it in the middle of the ring. It does not mind that. The only important thing is a stable connection between the Aufmaster and the connected cable using the clamps.
We show how this works in this video.
18 Where and how do I connect the Aufmaster?
For automatic cut detection, the Aufmaster is connected to the inner end of the cable drum or cable ring. To do this, strip a small piece of insulation and connect the two exposed wires to the clamps of the Aufmaster. The polarity does not matter. When determining the length of cables, the connection side is also irrelevant. The Aufmaster can then also be connected to the side where the cable is normally pulled out.
We show how this works in this video.
19 Can the Aufmaster also detect short circuits in cables?
Yes, this works – however, there is no separate function for this in the Aufmaster app.
The following scenario: A cable with a length of 100 meters is connected to the Aufmaster and the Aufmaster determines a length of 30 meters, then it can be assumed that there is a short circuit after 30 meters.
20 Do I need an Aufmaster for each drum?
We would like that, but it depends. If you're pulling cable in parallel with multiple drums at the same time, then, of course. If that's not the case, you can simply mount the Aufmaster on another drum after you've done your work, configure it, and keep on working. This applies equally to length determination and section detection.
