Simplicity and cutting edge technologies
Probably the world's smallest meter with such a large number of measurement functions. The functions are selected with a rotary switch. Additional parameters are set with buttons located on the housing face. The settings are saved by the device even when the battery is completely discharged.
All buttons and the modular display have backlight, which significantly improves operation in low light. Large memory eliminates the need for taking notes during the measurements.
Inspection of electrical safety
This device may be used to inspect safety of electrical systems in households and industrial facilities. Its main advantage is quick measurement (just a few seconds!) of fault loop impedance in circuits with RCD.
Measurements can be easily automated with:
- auto mode of residual current devices (RCD) tests,
- the WS adapter that can be used for testing systems via standard 230 V sockets
Earth resistance measurement
The device is ideal for measurements of earthing installations in residential buildings. It allows you to check the quality of the earthing system using the 3-pole method. Together with earth resistance result, the meter shows the interference voltage and the resistance of the auxiliary RS and RH probes.
Increased resistance to environmental conditions
The meter will cope well in difficult environmental conditions. Protection against penetration of dust and water is ensured by a unique housing with a level of protection IP67.
Communication and software
You can easily transfer measurement data to your computer via Bluetooth wireless communication. In order to generate a report on measurements for electric shock protection, use Sonel Reports PLUS software. Saving the downloaded data to the simplest formats and printing is provided by free Sonel Reader software.
