Tester for DIN VDE 0100 / IEC 60364.6 / GOST R (ГОСТ Р) 50571.16-99

for the measurement of loop resistance, determination of short-circuit current and the display of applicable fuse ratings.
In addition to complete testing for the effectiveness of RCDs, the instrument is also capable of phase sequence analysis, as well as the measurement of voltage and frequency. 

• The extremely rugged, two component housing with integral impact guard makes the PROFITEST C perfect for use by on-site installation teams, and it supplements the Profitest 204 in accordance with the new EN 60204 in an ideal fashion.
• A large, illuminated, anti-reflection graphic display allows for clear, intuitive, menu-driven operation, and operation is quick and easy with a total of only 5 keys.
• The integrated measurement value memory can be read out via the infrared data interface, which is included as standard equipment.  Print-outs and reports can also be read out via the IR interface, and it can be used for updates to assure that the instrument continues to meet future demands as well.
• Stored measurement values can be accurately assigned to their respective electrical circuits, distributors and buildings with the alphanumeric keypad.
• Unambiguous GO / NO-GO decisions are made possible with LEDs and display messages.
• Various languages can be selected for the user interface, and a phase tester has been integrated into the instrument.
• A carrying strap, a stand, holders for test probes and cables and a recharging socket for NiCd/NiMH batteries round out the convenient and safe PROFITEST C.

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 PROFiTESTDC-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.

Operation
The instrument is very easy to operate. A multifunction key allows for one-handed operation when selecting menus and starting measurements. Basic functions and sub-functions are selected with the help of four softkeys. For systems with earthing contact outlets, the instrument is simply connected to the mains outlet with the test plug.

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.

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.
