SourceMeter resistance as the core of the automatic test system

Resistor in the fixture in place, the issue of the trigger input signal to the 2400 population, 2400 to run pre-storage unit in its own testing procedures, test results obtained, and control mode selection signals and then send the data deposited in the computer, until a group of resistance testing completed, the system is in a wait state. During the test,[link widoczny dla zalogowanych], when the auto range Tian 30ms, each test time 0.5ms,[link widoczny dla zalogowanych], GPIB output a 4-bit ASC Ⅱ Temple readings i000s, 2400 population of Reading who lost data 1000s, the basic uncertainty meter test {test most patients with Yi 1997-N040.10%, resolution of 5 bits. 4 before the system software block diagram of ll2400 l2400GF18 very tough deposited set 'time-Jun {A, Cheng weigh format) Ib12400 set the power to see patterns (range.

Resistance is small ( 10Mf1), leakage current and thermal bound errors. 5.1 or higher test current resistance of conductor wire is long, with four-terminal resistance test method. By end 2400 the high impedance voltage measurement, covering the wire resistance. A 5r2 thermoelectric power thermoelectric power of amendment only by the bias compensation method test results, will short-circuit current test circuit, the output and the actual test current, the measured power (resistance that is constant thermoelectric power / test current) in ohms, in 2400 with FCTN front panel key will subtract from the test results of this impact,[link widoczny dla zalogowanych], but also through 2400CALCI subsystem, this value results from the test set I subtracted. 5,3 leakage current for the test fixture and connect the cable diarrhea leakage current, the first 21 * high resistance materials are used to reduce the effect of reducing by 2400 the latter cable ground terminal has decreased, as shown in Figure 3. ■ Screen tiny prince Yu stacked 3 figure,[link widoczny dla zalogowanych], the measured resistance Rx installed in two separate insulation resistance RL1, RL2, the 2400 V-G external connection terminal plate, the internal output for the follower, making the bottom and the top is almost RL on the same potential, the current flowing through RL is almost zero, all current through Rx, 2400LOin/Out terminal connected to the metal shielding cavity, to prevent common mode interference and other interference. 5.4 static charged object close to the measured resistance, often a large static electric field lines from the measured resistance is very close to the metal shielding cavity to reduce the impact. 6 Conclusion computer and digital source resistance of the table constitutes a continuous,[link widoczny dla zalogowanych], high-speed automated test system is a new field of electronic test suites here, if adopted by a multi-channel program-controlled computer switches to control multiple sets of test systems, to play fast and external computer speed and low equipment will enable higher performance and low cost test system has broad application prospects.
