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.
1.1 Introduction to Instrument
JK2516B 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.
JK2516B 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, JK2516B can meet
different test requirements ofdifferent 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~125V,190~250V
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 should correspond to the power plug of the instrument.
6) 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.
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,

4/17
direct sunshine and corrosive gas.
2)The instrument should operate under the temperature ranging from 0℃to 40℃,
relative
humidity of no greater than 75%. For high accuracy, use the instrument in the environment
above mentioned.
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)If the instrument will not be used for a long time, please place it in the original or a
similar
packing box. The environment temperature should be kept in the range of 5℃to 40℃,
and
the relative humidity should not be greater than 85%. The box should be located in an airy
room where it could be exposed corrosive impurities and direct sunlight.
7) 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: ≤30VA
2)Dimensions (W*H*D): 235mm*105mm*360mm; this dimension is the final packaging
size.
3)Weight: Approx. 3.6kg

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.

Measurement accuracy depends on measurement stability, temperature coefficient,
linearity,
repeatability and correction interpolation error.
Checking the measurement accuracy should be taken under the following circumstances:
a．Warm‐up time should be more than 30 minutes.
b．Correctly short the test cables, turn 0 ADJ to ON and perform short calibration by
pressing the touch key or 0 ADJ panel.
The correct short of the test cable is as follows:
