Is it necessary to modify the Detector I to get the new Detector II?

 

In theory the new firmware also runs on a Detector I (with some minor restrictions). However, we have agreed on sending in the Detectors for the upgrade onto the new firmware, so the hardware can also be modified.

Detector II: What time signals can be saved and what can be configured?

 

The Detector has 3 independent analogue branches, which means that 3 different time signals can be saved (demodulation, velocity between 2 Hz and 1 kHz and acceleration between 2 Hz and 20 kHz). In the Trendline software the user can select, whether to save a certain time signal always or to save it only, if one of the characteristic values has an alarm.

Detector II: Do I get different results when I measure with or without a headphone connected?

 

It is not possible to measure correct values and listen to the demodulated signal with a headphone at the same time. Please use the new menu item "Headphone" in the main menu.

When I try to turn the Detector on it switches off immediately. Is it broken and does it need to be returned?

 

The Detector is not broken, you must charge the battery. If the voltage of the battery drops below 4V, the Detector cannot be switched on to prevent battery damage.

I changed the language of the Detector to another language. Now I don't find the menu to change the language back again.

 

Go to the system menu (third or with 2.2.x-firmware fourth menu item in the main menu), then select "Change language" (first item in the list) and select "English" (again first item in the list).

The memory manager says, x kB of memory is used for time signals, although I haven't measured anything?

 

There are two types of time signals. In a configuration you can select to save a time signal always or to save it only if one of the characteristic values has an alarm. If you send a configuration to the Detector, the program checks it to find how many time signals must be stored always. The memory for these time signals is marked as reserved, so other time signals or free measurements cannot use that part of memory.

If I add up the used and free memory in the memory manager of the Detector, the values differ from the available memory?

 

Die Werte im Speichermanager sind gerundet. Zum Beispiel ergeben die Werte 25,4 kb und 15.4 kb , wenn die Werte einzeln gerundet werden 40 kb. Würde erst das Ergebnis gerundet werden, so ergäbe dies 41 kb.

If I switch the temperature sensor on, the Detector waits for another 5 seconds until a temperature is shown.

 

Der Temperatursensor benötigt nach dem Einschalten 5 Sekunden zur Initialisierung. Der Detector zeigt die Temperatur im Display an sobald er vom Temperatursensor eine gültige Messung erhält, etwa 5 Sekunden nachdem der Sensor eingeschaltet wurde.

The Detector says, I should switch the temperature sensor on, but it already is on!

 

The temperature sensor switches itself off after 2 minutes, even if the power button is "on". If you switch it off and on again, the Detector will read the correct temperature.

I cannot measure temperature anymore, this was no problem the last time I used it?

 

The battery in the temperature sensor is probably empty; replace it by a new one.

I bought a Detector II and compared the measured values with my Detector I, but they are not the same!

 

The Detector I has a high pass filter at 10 Hz with the velocity measurement and a 2 kHz high pass filter when measuring acceleration. In the Detector II these two high passes are removed, both now have a high pass at 2 Hz. If you measure with the Detector II and set up the corner frequencies at 2 kHz and 20 kHz, like the Detector I had, the measured values still differ. This is because the Detector I lowers signals at 2 kHz 3dB (-30%!), the new Detector doesn't. The Detector II uses the FFT (fast fourier transformation) to filter, so this filter has a very different characteristic.

I could have found a bug in the Detector firmware. What should I do?

 

Update to the newest firmware, which can be downloaded in the download section. During the update, the changes since the last versions are shown. When the bug is still there after the update, please contact our support department.

I would like to update the Detector firmware. How do I do that?

 

  1. Check the firmware version on your Detector. This is shown in the upper right corner after switching on the Detector or in the system menu under "Detector info".
  2. Download the newest firmware and the flashupdater program from Downloads. When your firmware version is the same as the one on our homepage, you don't need to update.
  3. Unzip (e.g. with Winzip) and install the flashupdater.
  4. Unzip the firmware file, at best in the dup-directory of the Flashupdater (e.g. c:\program files\FIS\DetectorFlashUpdater\dup).
  5. Start the Flashupdater via the startmenu (Programs -> FIS -> DetectorFlashUpdater) and follow the instuctions.
