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.

ST2829 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.
1.7 Other features
1) Power: consumption power≤80VA.

Parameter setup of FUNCB is the same as that of FUNCA, but FUNCB can
be turned off (OFF).
3.1.2 Test range
Measurement range should be selected in accordance with the impedance value
of the tested LCR component.
ST2829 has 11 AC measurement ranges: 10Ω, 30Ω, 100Ω, 300Ω, 1kΩ, 3kΩ,
10kΩ, 30kΩ, 100kΩ, 300kΩ, 1MΩ.
ST2829 has 14 DCR measurement ranges: 30mΩ, 100mΩ, 300mΩ, 1Ω, 10Ω,
100Ω, 300Ω, 1kΩ, 3kΩ, 10kΩ, 30kΩ, 100kΩ, 300kΩ, 1MΩ.
Operation steps for setting test range:
1) Move the cursor to the range zone, the following soft keys will be displayed:
AUTO The soft key is used to set the range mode to AUTO.
HOLD The soft key is used to switch the AUTO mode to the HOLD mode.
When the range mode is set to HOLD, the range will be locked in the
current measurement range. The current measurement range will be
displayed in the range zone.
↑(+) The soft key is used to increase the range under HOLD mode.
↓(-) The soft key is used to decrease the range under HOLD mode.
2) Use soft keys to set measurement range.
3.1.3 Test frequency
The measurement range of ST2829 ranges from 20Hz to 1MHz with an increase
or decrease of 0.01Hz. When the test function is set as DCR, the FREQ zone will
display “---”.
Operation steps for setting test frequency:
ST2829A provides two methods to set measurement frequency. The first one is to
use soft keys and the other one is to input data by using numeric keys.
1) Move the cursor to the FREQ zone, the following soft keys will be displayed.
↑(++)
This is a coarse adjustment soft key used to increase the frequency. Press
this key, the frequency will change as the following sequence: 20Hz,
100Hz, 1kHz, 10kHz, 100kHz, 200kHz and 300kHz.
↑(+)
This is a fine adjustment soft key used to increase the frequency. There
are 10 frequency points that can be set among the 10 times frequency
points. Press this key, the frequency will switch between the following
ones:
