The GPT-9900 Series is built upon a platform of  maximum power output 

 which 

supports the major test items complying with safety standards, such as IEC, EN, UL, CSA, 
GB, JIS as well as other safety regulations. 

AC 500VA

The GPT-9900 Series safety tester inherits every feature and advantages from the GPT-9800 
Series. The high-efficiency PWM amplifier, which is designed to impede the influence caused by 
voltage fluctuation of input AC source, is the core of GPT-9900 platform. The output voltage is 
automatically cut off (within 150μs) upon the detection of an abnormal output voltage or a 
trip of current limits during the measurement to protect the operators from hazardous injury. 
The safety tester will automatically discharge the DUT after each test to eliminate excessive 
voltage remained inside DUT.

Other significant functions and features of the GPT-9900 Series include the “Sweep” function, 
which is used to display the test results represented by the trace graph; The output terminal 
at the rear panel is used for system applications; The open-circuit detection is used to ensure 
proper connections of apparatus for ground bond test; 100 sets of memory can save and recall 
the panel settings for individual or sequential tests; A remote output on-off terminal at the 
front panel and a signal I/O port at the rear panel provide an external control for remote start/
stop of the safety tester; Thus, RS-232C, USB and GPIB (optional) interfaces are available for 
PC remote control and the storage of test results.

The Sweep Function is used to demonstrate 
the test results of DUT, which are represented 
by trace graph.  his helps users verify the 
changes of measured parameter (current or 
resistance)during the whole measurement 
process instead of one final value at the end.

The 240 x 64 LCD displays the necessary  
information such as test conditions, 
measurement results within single screen. 
Besides, the function keys arranged below 
the LCD display provide users with easy 
execution of test setup.

Any test conditions that have been 
previously stored can be used for a single 
test or combined together for automatic 
testing.

Except using the START/STOP buttons to 
control, the GPT-9900 series provides a 
remote terminal and a signal I/O port. 
Furthermore, the interfaces including 
RS-232C, USB and GPIB (option) within all 
the models allow users to retrieve test 
results via a PC connection.
