3. Product Description
The BENNING ST 750 A Appliance Tester has been developed for making the following measure-
ments for safety-related testing of electrical appliances in compliance with DIN VDE 0701-0702
(BGV A3) and DIN VDE 0751-1:
- measurement of the protective conductor resistance with compensation of the measuring line
- measurement of the insulating resistance
- measurement of the protective conductor current (alternative leakage current measurement,
direct current measurement or differential current measurement method)
- measurement of the contact current (alternative leakage current measurement, direct current
measurement or differential current measurement method)
- measurement of the device leakage current (alternative leakage current measurement, direct
current measurement or differential current measurement method)
- measurement of the leakage current of the applied part (alternative leakage current measure-
ment or direct current measurement method)
- functional test with measurement of input voltage, input current, effective power and apparent
power
- testing of IEC leads and extension cables
3.1 Scope of Delivery
The scope of delivery of the BENNING ST 750 A includes:
1 x BENNING ST 750 A Appliance Tester
1 x 2 GB SD memory card
2 x 1 m connecting cable with 4 mm safety plug
1 x IEC connecting cable (for line test)
2 x safety probe tip (red, yellow) with 4 mm safety jack
2 x alligator clip (red, black) with 4 mm safety jack

3.2 Transport / Storage /Operating Conditions
The device is designed for being operated under the following conditions:
Ambient conditions: height up to 2000 m above sea level
Temperature range: 0 to 35 °C (operating temperature)
- 20 to 60 °C (storage temperature)
Max. relative humidity: 80 % to 30 °C, linearly decreasing
60 % to 40 °C, non-condensing
Under the carrying handle, the device is provided with a manual pressure valve: Turn it to the right
(in clockwise direction) to close the valve (CLOSE) and to see a red indicator triangle. Turn it to
the left (in counter-clockwise direction) to open the valve (OPEN) and to see a green indicator
triangle. To protect the device and for long transport, it is recommended to close the valve. To open
thedevice,rstopenthevalve(forpressurecompensation)andthenopenthecover.Pleasealso
refertochapter20("TechnicalData").Pleasekeeptheoriginalpackagingforlaterdispatch,e.g.for
calibration. Transport damage due to improper packaging are excluded from warranty. Please store
the appliance tester under dry conditions in closed rooms. If the device has been transported at
extreme temperatures, it needs an acclimatization phase of at least two hours before switching it on.
3.3 Model and Type Designation
A type plate indicating the series number is located inside the housing (on the left next to the con-
nections for peripheral devices). If you have any queries, please always state the product designa-
tion and the series number.
3.3.1 Environmental Protection
At the end of product life, dispose of the unserviceable device via appropriate collecting
facilities provided in your community.
