Automatic Transformer Test System 3300/3302 User’s Manual
(4) Secondary Turn-Ratio and Phase appropriate terminal
2 individual BNC sockets, in testing PH and turn ratio period connect an external test device
or wire to transformer secondary side for unknown measurement.
Sec(+) : voltage inspector terminal, high voltage.
Sec(-) : voltage inspector terminal, low voltage.
(5) Selective key
The major function is to show the different conditions of each function or other options which
need to be selected according to the user’s requirement.
(6) The functions of measure display (3302 only)
After press this key then the instrument is in basic component measure & analysis condition.
Under this screen each test parameter can be changed directly and the value can be read out.
For example, test voltage, parameter, speedy, series or parallel…etc.
(7) Main function key
Press this key for entering the main index screen. In this screen you may select what you
want to test, for example, transformer test function, the analysis of unknown test result,
statistic of unknown test result, multi-frequencies scan test, open test, short test,…and so on.
(8) System parameter setup key
Press this key for entering the main system parameters setup, each system parameters can be
changed directly under this screen. For example, the function of calibration in this
instrument, set the store data function, set the data recall function, set the system data and
time function, select and set the each system reveal able parameter and measure parameter
(the function of calibration entrance need password)
(9) Cursor key
There are up, down, left, right four keys, these keys are for display in difference kinds
condition, to control cursor can be useful to input each parameter, can also be selective keys,
for example, change value like setting frequency or voltage.
(10) Start/Trig key
Start to test the unknown, when the measure condition of instrument is external trigger or
manual trigger, press this key to measure.
(11) Numbers and symbol key (0…9.-)
These numbers and symbols are for each setting condition that need to input value and
