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
ST2515 is a DC Resistance Meter with color LCD display and touch function. Its accuracy of 0.01%
is able to meet general resistance test requirements. Better measurement result is obtained for
temperature-sensitive resistors by the adoption of temperature compensation function. Statistic
function has the capacity to make statistic analysis of massive test data.
ST2515 is a powerful test tool for all kinds of resistor design, detection, quality control and
production. Its high test speed is applicable to the spot-check machines on production lines. With
multiple output data and comparison mode, ST2515 can meet different test requirements of
different resistor manufacturers. The prominent performance makes the test results come up to
IEC and MIL 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 to 240V (dependable on the voltage setup on the rear panel).
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
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 ensure that the earth ground wire is safely grounded.

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) Operating conditions:
Temperature 0°C to 40°C
Relative humidity ≤80%, no condensation
Storage conditions:
Temperature -10°C to 50°C
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.
2) Do not turn on or off the instrument frequently. This may cause internal data confusion.
1.8Other Features
1) Consumption: ≤10VA
2) Dimensions (W*H*D): 235mm*104mm*360mm; this dimension is the final packaging size.
3) Weight: Approx. 3.6kg

zone.
↑ (+) Increase the range.
↓ (-) Decrease the range.
2) Touch the corresponding soft key to select the required range.
3.1.3 Measurement Speed
The measurement speed of ST2515 is decided by the following factors:
Integral sampling period (approx. 5ms)
Average times (measurement times)
Measurement delay time (a time starting from the measurement start-up to the
measurement beginning)
Time showing measurement result
Three measurement speeds are available on ST2515: FAST (fast, approx. 50meas/sec), MED
(medium, approx. 6meas/sec) and SLOW (including SLOW1 and SLOW 2, approx. 2meas/sec).
Operation steps for setting measurement speed:
ST2515 displays the measurement result as a 6-digit number in the decimal point floating mode.
In FAST mode, the result is shown as a 5-digit number while in MED and SLOW, as a 6-digit
number and temperature as 4-digit.
1) Touch the speed zone, the following soft keys will be displayed.
FAST
MED
SLOW1
SLOW2
2) Use above soft keys to modify the speed.

format. Before a U disk is inserted, the save function will be disabled.
2) As for File Manage, please refer to 4.2 for details.
3.1.5 Tools
Operation steps for setting tools:
Touch TOOLS, the following soft keys will be displayed in the soft key zone.
Display (ON/OFF): Display the measurement result or not. ON is to display, OFF is not to

0 ADJ (ON/OFF): OFF means the base number at the short correction will not be subtracted
while ON is to subtract the base number.

ST2515 Operation Manual
11
0 ADJ: Execute short correction. In this process, please ensure the test terminals have been
correctly shorted. Only by doing this, unexpected measurement errors could be avoided.
OVC (ON/OFF): ON is to use offset voltage compensation for measurement results. OFF is
not to.
Correction: Auto and Manual
Save data: Touch the screen or press the corresponding button to save the current
measurement results to a U disk. If no external U disk is found, this function will be inactive.
Once a U disk is found and this function is selected, the corresponding soft key will be
displayed as STOP SAVE and you can press this soft key again to terminate this operation.
NOTE:
SPEED: In SLOW2, SLOW1 or MED mode, the measurement result is a 6-digit number while FAST
is a 5-digit one.
SAVE: Once START SAVE is selected, you must press STOP SAVE to terminate and close the file
properly or the saved data will be lost.
SHORT: When this key is used to take short correction, the test fixture should be correctly
connected. If not, the deducted data will be wrong, and further it will cause result errors. The
correct connection is shown as the following figure.

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.
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.
