Special Testing for Systems and RCCBs Testing for Special RCCBs
Measurement of line voltage and frequency, phase angle and sequence
Measurement of loop and earthing resistance
Special Features
- Allowable fuse types are displayed for the system under test.
- Internal measurement value memory with 32 kB capacity stores up to 255 electrical circuits and up to 2000 measurement values.
- Data interface for the transmission of measurement values and for software updates
Voltage and Frequency Ranges
The measuring device allows for use of the test instrument in all alternating and three phase current systems with voltages ranging from 170 to 253 V, and frequencies from 15 to 70 Hz.
Loop Impedance Measurement
Loop impedance measurement can be performed within a range of 170 to 253 V. Subsequent calculation of short-circuit current is based upon the respective line voltage, assuming that the measured line voltage is within the specified range. If line voltage is not within the specified range, short-circuit current is calculated based upon actual line voltage and measured impedance. RCCB tripping can be suppressed for the measurement of loop impedance with the PROFiTESTDC-II accessory device.
Display
The LCD window consists of a backlit dot matrix which is used to display menus, configuration options and measurement results, as well as online help. Various user interface languages can be selected, depending upon the country in which the test instrument is used.
Phase Tester
Protective conductor potential is tested when the finger contact surface is touched. The PE signal lamp lights up if a potential difference of greater than 150 V is detected between the contact surface and the earthing contact at the test plug.
Battery Charge Level Indicator and Device Self-Test
A battery symbol in the main menu with 5 segments ranging from depleted to fully charged keeps the user continuously informed concerning battery charge level. Test patterns can be queried one after the other in the self-test mode, and display LEDs and relays can be tested. The test instrument is switched off automatically if the batteries are depleted, and it includes a charge control circuit for safe charging of commercially available rechargeable NiMH or NiCd batteries.
Sturdy Housing for Rugged Use
Soft plastic jacketing protects the instrument against impacts, or if it is inadvertently dropped.
Signal Lamps
The device recognizes errors in the electrical system automatically, which are indicated with four lamps, (see following table).

Data Interface
Measurement data can be read out to a printer or a PC via the integrated IRDA interface, providing the user with 3 advantages.
- Transmission of stored data to a PC for processing and archiving, or for the generation of official reports
- Immediate print-out of all measurement data (via adapter)
Software Updates
The test instrument will never become obsolete thanks to software updates which can be installed via the IRDA interface. Updates can be performed by our service department as part of our re-calibration service, or by the user himself.
