Loaner: Benning ST 725 (050316)

Mains-operated and Battery-operated Appliance Tester for Mobile Testing of Electrical Devices

• mobile – network-independent testing due to battery operation
• easy – operation by means of push-buttons
• quick – testing within a few seconds
• all-in-one – protective conductor current measurement by means of differential current or alternative leakage current measurement method

Testing of devices with mains voltage-dependent switching elements / mains supply units / relays such as controlled devices / tools, devices of information and communication technology as well as of devices which can be tested completely with mains voltage only.
In mains operating mode, the protective conductor current/ contact current is measured by means of the required differential current / direct measurement method.

New product features

• storage locations for 999 test samples
• 3 hot keys for storing, calling and printing the measured values
• mini-USB interface and download software for the preparation of test certificates in MS Excel®
• direct printing function for printing test certificates on site by means of optional printer BENNING PT 1 (044150)
• prolonged functional test and differential current measurement (max. 2 x 5 minutes)
• integrated real-time clock for storing the measured values including the test date

Features

• automatic testing procedure for devices of class I (key 1), class II/III (key 2) and line test (key 1)
• testing of cable reels, multiple distributors and device connecting cables with IEC connector
• measuring result with "PASS / FAIL" indication
• limiting values preset
• mains operating mode for tests under operating conditions
• battery operating mode for mobile testing
• reduction of the ISO testing voltage for devices with overvoltage arresters
• indication of correct function key in case of incorrect operation, overload and if the test sample is not switched on
• sufficient battery capacity for more than 2,500 test samples

Measuring functions:

• protective conductor resistance with a pulsed testing current of ≥ 200 mA (required in case of oxidized contacts)
• insulating resistance with a testing voltage of 250 V or 500 V)
• mains operating mode: protective conductor current/contact current by means of differential current/direct measurement method with automatic mains pole reversal
• battery operating mode: protective conductor current/contact current by means of alternative leakage current measurement method
• active testing of three-phase devices under operating conditions by means of optional measuring adapters (item no. 044140 / 044141)
• testing of permanently installed and portable 30 mA RCDs / PRCDs with tripping time measurement
• voltage measurement on external shock-proof socket
