Appliance Tester BENNING ST 725

testing in compliance with DIN EN 50678 (VDE 0701) and DIN EN 50699 (VDE 0702)
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 2 (10225404)
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
