Automatic Transformer Test System 3300/3302 User’s Manual
The initial value is "00". There are 10000 choices. The way to control is to use the key
beside the cursor, move it from the block to "delay time". Then press [ ] and [ ] to
change it. Normally, the value of L of transformers are not large, so set this parameter "00"
is enough, except over 100mH then need to adjust.
When measure DCR of inductance, if inductance value is 100mH
〜
200mH, than DELAY
TIME need to be set to "01", if inductance value is 200mH
〜
300mH, than DELAY TIME set
to "02", as follow this, if inductance value less than 100mH, than DELAY TIME set to "00",
then the measured value of DCR is correct.
AVERAGE TIME:
By choosing the average setting such as "01", the program would take the average in each
time of measurement. If the setting is "02", the program would take average in two times of
measurements. Following vest can be deduced accordingly. The standard setting is "01",
which means the control range is 01
〜
10. By moving the cursor key to right hand
side of AVERAGE TIME and changes the range with [ ] and [ ] keys.
HARD COPY:
It can be set up to directly print by choosing, one of three different choices ON/INV./OFF.
INV. means to print the stuff that be highlighted. It can move cursor key to right hand
side of HARD COPY and set up different function of [ON], [INV] and [OFF].
SHIFT POS:
By choosing the printing result position, it can be set from "00" to "100". The range of
control is "00"
〜
"250". It can be chose the range by moving the cursor key to right
hand side of SHIFT POS and change with [ ] and [ ] keys or directly choose from
PROGRAM menu.
PARAMETER Z: (3302 only)
To measure L.C.R, it also indicates the functions of Z and Q value. By moving the cursor
key to right hand side of PARAMETER Z, it will display [ON] and [OFF] function and
choose one of them.
LINK 1320: (3302 only)
If intend to link with 1320, If test-objected, is a larger inductance (Lx>10mH), the tester has
to do open zero first. By moving the Cursor key to right hand side of LINK 1320, it
will display [ON] and [OFF] function and choose one of them.
SPECIAL TR:
When in measuring turns-ratio, if "Related (-
μ
r)" value of coil less than 100, there’s leaking
magnetic phenomenon occurred at secondary. Then, by moving the Cursor key to
right hand side of SPECIAL TR, it will display [ON] and [OFF] function and choose one of
them. Only at Scan Box can be used.
