Notes
In order to prevent accumulation of static electricity inside the running tester,
make reliable ground connection via its ground terminal before the test.
Be caution when output voltage is over 36V, this might cause some electric
accident. Keep safety and avoid this situation occurring.
When high current is being outputted, avoid personal injury and the equipment
damage, which is under test.
Never add external voltage and current onto the voltage/current output
terminals of the tester.
Since the tester is a kind of precision electronic equipment, keep a water-proof
and damp-proof environment for it.
Find any abnormal signs during the installation of the tester, please inform
factory immediately and don’t fix it by yourself.

1. General Introduction
The T500 series single phase relay test kits are designed for easy and safe test of
different type of relays. The powerful 250A/2000VA current source can be used to test all
kinds of current relays, including high burden relay and C T. The AC/DC current and/or
voltage sources allow phase angle and frequency to be adjusted smoothly. This makes it
possible to precisely test directional and frequency relay. The kit uses advanced switching
power amplifier to replace the traditional transformer, thus avoiding the dangerous high
voltage across the current output.
T500 series universal tester offers 2 types of products: T200A/T1000.
