Instruction Manual Description The ST-AC Pro’ high frequency tester comprises of a lightweight, hand-held probe connected by a cable to a portable generator. A robust aluminium case houses the generator and its components. On the front panel of the case there is: ●...
ST-AC Pro’ Unpacking The ST-AC Pro’ and the handle should be removed from their bags and be checked for damage. If any part is damaged, the carrier and supplier should be notified immediately. All packing material should be kept for inspection and the ST-AC Pro’ should not be used.
Instruction Manual The high voltage generated by this unit is at a frequency of 100KHz, well above the motor frequency of the human central nervous system. A serious shock is unlikely if the probe is accidentally touched during operation, however it is likely to be painful, and may result in localised burns.
ST-AC Pro’ Ensure that the mains supply is disconnected, and then screw the flexible probe electrode into the red end of the handle. WARNING: do not connect electrodes whilst the generator is connected to the mains supply. Set the output control knob fully anti-clockwise (Output OFF) and check that the mains ON/OFF switch is in the OFF position.
7,500V test voltage, make sure that all the faults are detected. The output voltage of the ST-AC Pro’ can be roughly set by dividing the test voltage by 1700, the answer is in mm e.g. 20,000/1700 = 11.75mm. Hold the test probe at the calculated gap from a piece of earthed metal and increase the output voltage until the spark jumps the gap.
1000:1. Adjust the output of the ST-AC Pro’ for the item under test (see: How to choose the test voltage). Slowly sweep the area to be tested, looking at the probe at all times. When a fault is passed over, the high-voltage probe discharge will change to a single spark.
Instruction Manual Electromagnetic compatibility Electromagnetic Emissions - European Union Directive: Before operating this equipment it is essential that the following action be taken. Risk assessment As this equipment will produce an electromagnetic emission, when actually arcing down through a fault to earth, a risk assessment of the area in which the unit will be used should be carried out.
ST-AC Pro’ have the same effect if you were testing a plastic tank. If you were testing the circumference of a metal pipe then the pipe could act as an aerial and transmit the emissions further than expected. Please bear in mind that electromagnetic emissions travel in all directions and can even be bent or deflected.
