Declaration
The descriptions contained in this manual may not cover all information about this instrument.
Introductions to the improvements of the instrument in performance, function, internal structure,
outer appearance, accessories, packing material, etc. are subject to change without notice. If you
find any inconformity of this manual with our instruments, please contact us for further
consultation by the address listed on the cover.

TH2516 Series Operation Manual

1) Introduction to Instrument, Unpacking and
Installing
Thank you for your purchase and use of our products! This chapter will introduce the basic
instrument performance, which is followed by notes of unpacking and installing.
1.1Introduction to Instrument
TH2516 adopts 32 bits CPU and high density SMD technology. 24 bits, 4.3-inch and touch LCD
screen brings ease for your eyes and convenience to your operation. The maximum 0.05%
accuracy and minimum 1 µΩ resolution shore up its leading role in testing relay contact resistance,
interconnecting resistance, conductor resistance, PCB resistance and welding-hole resistance.
Temperature compensation and conversion functions make your tests be free from the effect of
the environment temperature. The offset voltage compensation has effectively eliminated the
electromotive force of the DUT and its contact potential difference. For the contact influence of
the thermoelectricity on DUT, its elimination is achieved; especially when the resistance changes
with the temperature greatly, better test results will be achieved. With statistic analysis function,
the instrument can make statistic analysis for a large number of test data.
TH2516 series is a powerful test tool for all kinds of resistor design, detection, quality control and
production. Automation on production lines can be greatly improved by the realization of
ultra-high test speed and the signal output of 3 compare results through HANDLER interface.
With multiple output data display, comparison mode and bin comparator, TH2516 series can
meet different test requirements of different resistor manufacturers. The prominent performance
makes the test results come up to IEC and IML standard.
1.2Unpacking
Inspect the shipping container for damage after unpacking it. It is not recommended to power on
the instrument in the case of a damage container.
If the contents in the container do not conform to the packing list, notify us or your dealer.
1.3Power Connection
1) Power supply: 90V-125V, 190V-250V
2) Power supply frequencies: 50Hz and 60Hz
3) Power supply power range: ≤30VA
4) L (line wire), N (neutral wire) and E (earth ground wire) of the power supply input socket

TH2516 Series Operation Manual

should correspond to the power plug of the instrument.
5) The instrument has been specially designed for decreasing noise jamming caused by the
input in AC power terminal, but it is also recommended to use it in the environment of low
noise. If noises cannot be avoided, install a power source filter please.
WARNING: To avoid injury to personnel and damage to the instrument resulting from electric
shock, do sure that the earth ground wire is safely grounded.
There is selector switch between 110V and 220V voltage besides the power
interface on the rear panel. Please switch correctly.
1.4Fuse
The fuse is a standard configuration, so use the included custom fuse please.
1.5Environment
1) Do not store or use the instrument where it could be exposed to many dusts, great vibration,
direct sunshine and corrosive gas.
2) Working condition:
Temperature: 0℃to 40℃Relative humidity: ≤80%No condensation
Storage condition:
Temperature: -10℃to 50℃Relative humidity: ≤90%No condensation
3) For high accuracy, do not block the left air vent so as to ensure good ventilation.
4) The instrument has been specially designed for decreasing noise jamming caused by the AC
power input, but it is also recommended to use it in the environment of low noise. If noise
cannot be avoided, install a power filter please.
5) Test leads on the instrument that are connected to DUTs should be kept away from strong
electromagnetic fields to avoid interference.
1.6Use of Test Fixture
Only use the test fixture or cable made by our company, because the use of other test fixtures or
cables may result in incorrect measurement results. In addition, for good contact of DUT and
fixture, keep the test fixture or cable and pins of DUT clean.
Connect the test fixture or cable to HI and LO terminals on the instrument front panel. Ensure the
color and arrow conformity of the test fixture with that of sockets on panels, thus to avoid
abnormal measurement.
1.7Warm-up
1) For accurate measurement, the warm-up time should not be less than 30 minutes.

this function will be disabled.
Save Data OFF: Touch this key, this key will turn to <Save Data ON> and each measurement
result will be continuously saved to the .CSV file in U disk. Before a U disk is inserted, the
save function will be disabled. Press the key again, this key will turn to <Save Data OFF> and
the measurement result will not be saved. When switching between ON and OFF once, a
new .CSV file will be created in a U disk. The measurement data can be analyzed by opening
the file through the computer.
2) Refer to 4.2 for more details about FILE MANAGE.
3.2.2 Tools
Touch <TOOLS>, the following soft keys will be displayed.
DISP (ON/OFF): ON is to display the measurement result and OFF is not to.
BEEP (NG/GD/OFF): NG: The beeper will sound when the measurement result is not
consistent with the setting value. GD: The beep will sound when the measurement result
conforms to the setting value. OFF: Turn off the beeper.
COUNT (ON/OFF): ON：Start count; OFF: Stop count.
COUNT CLEAR：Clear the count numbers of TOT, IN, HI and LO and start count from zero.
DISP MODE NORMAL: press the key, DISP Mode DEV will be displayed. The value of
deviation △will be displayed in the main display interface and the display range is
-99.9~999.9%. Press the key again and DISP MODE NORMAL will be displayed.
NOTE: △={( measured resistance value - nominal resistance)/ nominal resistance} x 100%
3.2.3 COMP (ON/OFF)
COMP (ON/OFF): ON indicates the compare function has been turned on. Only when the
compare function is in ON mode, count and beep function can be enabled.
OFF is to turn off this function.
3.2.4 Compare Mode and SETTINGS of ABS & Percent Error
You can set the compare mode and concerned values by touching the screen or pressing
keyboard. There are two compare modes: ABS and %.
Compare modes:
1) ABS (high and low limits)
In this mode, you can set low and high limits. The instrument will take comparison between the
tested values and the set ones so as to judge the DUT is HI or LO or IN. The set upper limit value
should be equal or larger than the lower limit value.
2) % (percent error)
In this mode, you can set the nominal value and the percent error. If you set the nominal value as
100 and percent as 10, the set value should be 100±10%. The instrument will take comparison
between the tested values and the set ones so as to judge the DUT is HI or LO or IN. The nominal

value is the base value in bias display mode.
