GPT-9904.

The GPT-9904 from GW Instek is a GPT-9900 series A.C. 500VA AC/DC withstanding voltage/insulation resistance/ground bond tester. The high efficiency PWM amplifier is the core of GPT-9902A platform design to impede the influence from voltage fluctuation of input AC source. The output voltage is automatically cut off (within 150μs) upon the detection of an abnormal output voltage or a trip of current limits during test to protect the operator from hazardous injury. The GPT-9902A automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT. Following a tidy and easy to use design concept, the tester is equipped with a simple & clear panel layout, a high resolution dot matrix LCD display and colour LED indicators allowing operators to interpret measurement results easily and quickly. The sweep function of GPT-9904 is able to display test results point by point all through the testing period to form a trace graph.
