Gossen Metrawatt M521D Offers

Features

• M521D PROFITEST C Tester for VDE 0100 / IEC 60364.6
• 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

Testing of Residual-Current Devices (RCDs)

• Measures contact voltage without tripping the RCCB. Contact voltage relative to nominal residual current is measured with 1/3 nominal residual current
• Trip test with nominal residual current and measurement of time to trip

Special Testing for Systems and RCCBs

• Testing for systems and RCCBs with rising residual, tripping current is displayed
• Testing for RCCBs (10, 30mA and 100mA) with 5IN
• Tests RCCBs with half-waves in order to determine contact voltage and tripping current

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 253V, and frequencies from 15 to 70Hz.

Loop Impedance Measurement

Loop impedance measurement can be performed within a range of 170 to 253V. 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 PROFiTESTC-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 150V 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.

Applications

Ideal for the following applications: New Construction, Electricians, Plant Maintenance.
