Announcement
The description of the manual may not cover all contents of the instrument, and
our company is subject to change and to improve the performance, function,
inner structure, appearance, accessory and package of the instrument without
notice. If there is puzzle caused by inconsistency of manual and instrument, then
you can contact with our company by the address on the cover.

TH2829X Series Operation Manual Chapter 1 Out of Box Audit

Chapter 1 Out of Box Audit
When you receive the instrument, some inspections are necessary, and the
condition must be understood and available before installing the instrument.
1.1 To Inspect the package
Inspect the shipping container for damage after unpacking it. It is not
recommended to power on the instrument in the case of a damaged container.
If the contents in the container do not conform to the packing list, notify us or
your dealer.
1.2 Power connection
1) Power-supplying voltage range: 100~120Vac or 198~242Vac. Being related
with the power setup on the rear panel.
2) Power-supplying frequency range: 47~63Hz.
3) Power-supplying power range: less than 80VA.
4) Power supplying input phase line L, zero line N, ground lead E should be as
same as the power plug of the instrument.
5) After careful design, the instrument can reduce the clutter jamming caused
by AC power terminal input, however, it should be used under the
environment with low-noise. Please install power filter if being unavoidable.
———————————————————————————————————————
Warning: In order to prevent user and instrument from being hurt by
leakage, it is necessary for user to guarantee the ground line of supply
power being reliably grounded.
———————————————————————————————————————
1.3 Fuse
The instrument has installed fuse, so operators should use the installed fuse of
our company.
———————————————————————————————————————
Warning: Be sure that the location of fuse is consistent with
power-supplying voltage range before charging.
———————————————————————————————————————

1.4 Environment
1) Please do not operate the instrument in the place that is vibrative, dusty,
under direct sunlight or where there is corrosive air.
2) The normal working temperature is 0℃～40℃, relative humidity ≤75%, so
the instrument should be used under above condition to guarantee the
accuracy.
3) There is heat abstractor on the rear panel to avoid the inner temperature
rising. In order to keep good airiness, please don’t obstruct the left and right
airiness holes to make the instrument maintain the accuracy.
4) Although the instrument has been specially designed for reducing the noise
caused by ac power, a place with low noise is still recommended. If this
cannot be arranged, please make sure to use power filter for the instrument.
5) Please store the instrument in the place where temperature is between 5℃
and 40℃, humidity is less than 85%RH. If the instrument will not be put in
use for a time, please have it properly packed with its original box or a similar
box for storing.
6) The instrument, especially the test cable should be far from strong
electro-magnetic field, to avoid the jamming on measurement.
1.5 Use of Test Fixture
Please use the accessory test fixture or cable, the test fixture made by user or
from other company may cause the incorrect measurement result. The
test fixture or cable should be kept clean, as well as the pin of DUT, thus to
guarantee the good connection between DUT and fixture.
Connect the fixture or cable to four test terminals Hcur, Hpot, Lcur, Lpot on the
front panel. As for the DUT with shielding shell, connect shielding layer or ground
“┴” .
Note: When test fixture or cable has not being installed, the instrument will
display an unstable test result.
1.6 Warm-up
1) To guarantee the accurate measurement, the warm-up time is no less than
15min.
2) Please not turn on or off instrument frequently, in order to avoid the inner
data fluster.

2.5 Basic Operation
Basic operation of TH2829X is as follows:
Use menu keys ([DISP], SETUP], [SYSTEM]) and soft keys to select the
desired page.
Use cursor keys ([←][→]) and the slide switch to move the cursor to the
desired zone. When the cursor moves to a specified zone, the zone will
become reverse expression.
The soft key functions corresponding to the current zone of the cursor will be
displayed in the soft key zone. Users can select and use the desired key.
Numeric keys, [BACKSPACE] and [ENTER] are used to input data.
When a numeric key is pressed down, the usable unit soft key will be
displayed in the soft key zone. You can choose a unit soft key or press [ENTER]
to end data inputting. When [ENTER] is used to terminate data inputting, the
unit of data will be set to a default unit, such as Hz, V or A. For example, the
default unit for frequency is Hz.
