Brief description
This instrument from BJZ is a compact teraohmmeter (resistivity meter). The Safe-STAT RM 4000 measures surface resistance, volume resistance, and resistance to ground in accordance with IEC 61340 using test voltages of 10 V or 100 V. The device comes with an integrated temperature and humidity probe, an SD card slot, and a built-in barcode/QR scanner (or alternatively an RFID scanner).
Functions and data management
- Individual programming of limit values in the range of 5 kΩ to 2 TΩ.
- Use of color change in the display to indicate limit exceedance.
- Automatic storage of measurement results (resistance, category, measurement voltage, temperature, humidity, date, and time) as a TXT file on an SD card.
- Intuitive operation via touch-screen.
- Power supply via built-in Li-ion battery or USB-C (requires 5 V, min. 1 A - not included).
Typical applications
The Safe-STAT RM 4000 is used for documenting and recording measurements in connection with the testing of EPA equipment, as well as during internal and external audits, where recorded parameters such as resistance, measurement voltage, temperature, and humidity must be saved and linked to a measurement object via barcode/QR or transponder.
Documentation
Measurement data is automatically saved as a TXT file on an SD card and can be processed in the included Excel-based software. After assigning a barcode or transponder, results can be categorized (e.g., plant, site, user, inventory number) and linked to the respective measurement object.
