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.

JK2830 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: 99~243Vac. Being related with the power
setup on the rear panel.
2) Power-supplying frequency range: 47~63Hz.
3) Power-supplying power range: less than 20VA.
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.

When the output impedance is selected as 30Ωand 50Ω, JK2830 has 6 AC
measurement ranges: 10Ω, 30Ω, 100Ω, 1kΩ, 10kΩ and 100kΩ.
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.
3.1.3Test frequency
The measurement range of JK2830 ranges from 50Hz to 200kHz, total 37
frequency points.
Operation steps for setting test frequency:
JK2830 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: 50Hz,
100Hz, 1kHz, 10kHz, 100kHz, 200kHz.
◼↑(+)

400 Hz 4 kHz 40 kHz
500 Hz 5 kHz 50 kHz
600 Hz 6 kHz 60 kHz
800 Hz 8 kHz 80 kHz

JK2830 Series Operation Manual Chapter 3 Introduction to [DISP]
14
◼↓(-)
This is a fine adjustment soft key used to decrease the frequency. The
selectable frequencies are the same as that of ↓(-).
◼↓(--)
This is a coarse adjustment soft key used to decrease the frequency. The
selectable frequencies are the same as that of ↓(--).
2) Use soft keys or numeric keys to select or set frequency. When using numeric
keys to input the required frequency value, the soft key displays the available
frequency units (Hz and kHz). You can use unit soft key to input unit and data.
When using [ENTER] to input frequency, the default unit is Hz.
3.1.4Test level
The measurement level of JK2830 can be set from 10mV to 2.0V with the
resolution of 10mV.
Operation steps for setting test level:
JK2830 provides two methods to set the level of test signal source. The first one
is to use soft keys, while the second one is to input data by numeric keys.
1) Move the cursor to LEVEL, the following soft keys will be displayed.
◼↑(++)
This is a coarse adjustment soft key used to increase the level of test
signal source.
◼↑(+)
This is a fine adjustment soft key used to increase the level of test signal
source.
◼↓(-)
This is a fine adjustment soft key used to decrease the level of test signal
source.
◼↓(--)
This is a coarse adjustment soft key used to decrease the level of test
signal source.
2) Soft or numeric keys are used to select or set the test level. When numeric
keys are used to input the desired level, the available units (mV, V,uA,mA,A)
will be displayed in the soft key zone. Users can use these unit keys to input
unit and data.
