ST2516 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.
1.1
Introduction to Instrument
ST2516 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.
ST2516 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, ST2516 series can meet different test requirements of different resistor manufacturers. The prominent performance makes the test results come up to IEC and IML standard.

Temperature Correction (TC)
Temperature correction (TC) : By this function, the resistance tested under the current environment temperature will be converted to a resistance value under the user-set environment temperature. For instance, a resistor is tested as 100Ω under 20 ℃ . If user sets the temperature as 10 ℃ , after correction, the value will be disp layed as 96.22Ω. This is realized by formulary conversion.
Formula: Rt=Rt0*{1+ ɑt0*(t -t0)}
Rt Resistance measured under the current environment temperature

NOTE: Before measurement, it is necessary to warm up the instrument and the probe for about half an hour. The temperature sensor should be placed to the DUT as close as possible but cannot contact it. After the displayed result comes to be stable, you can read or record the result.
3.6.2 Temperature conversion (∆t)
Temperature conversion (∆t) : Basically, resistors have heat effect. Temperature conversion represents the temperature difference between the resistor and the environment.
Formula:
R
R

+ − +
)
∆ t is the temperature increment. t1 is the temperature at the start of resistance measurement. ta is the environment temperature.
R1 is the resistance at the start of contact.
R2 is the resistance after the display is stable.
K is the variance ration of the environment temperature coefficient when the conductor is at
0 ℃ .
For example
When R1 is 2 00mΩ, t1 is 20 ℃ and k is 235.
Δ t =

The temperature after the resistance is stable is calculated as the following formula: 𝑡

6.1
RS232C Connection
RS-232 standard, also called as asynchronous serial communication standard, has already been widely used for data communication between computers, computer and external equipment. RS is the English abbreviation of Recommended Standard; 232, the standard number. This standard is issued by EIA in 1969, which rules to send one bit in a data line every time.
As most serial interfaces, the serial interface of ST2516 is also not strictly based on RS-232 standard but only uses the smallest subset of this standard. The signals are listed in the following table.
