- A)
For measurements from the front edge of the measuring tool, this applies for high reflectivity of the target (e.g. a white-painted wall), weak backlighting and 25 °C operating temperature. In addition, a deviation of ±0.05 mm/m must be taken into account.
- B)
For measurements from the rear edge of the measuring tool, applies to low reflectivity of the target (e.g. a dark-painted wall), strong backlighting and –10 °C to +45 °C operating temperature. In addition, a deviation of ±0.15 mm/m must be taken into account.
- C)
In continuous measurement mode, the max. operating temperature is +40 °C.
- D)
Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.
- E)
Bluetooth® deactivated
- F)
At an operating temperature of 25 °C
- G)
After user calibration at 0° and 90°; An additional grade error of ±0.01°/degree to 45° (max.) has to be taken into account. The left-hand side of the measuring tool serves as the reference level for grade measurement.
- H)
Except battery compartment
- I)
When using Bluetooth® Low Energy devices, it may not be possible to establish a connection depending on the model and operating system. Bluetooth® tools must support the GATT profile.
The serial number (11) on the type plate is used to clearly identify your measuring tool.
