Positive contact assures reliable measurements. Always-On Contact Checking High-speed, reliable measurements are achieved by performing contact checks while measuring (instead of before and after, as done until now). Contact Check While Measuring • Detects probe bounce Contact a n d c o n t a c t r e s i s - Condition tance fluctuations while measuring • Minimizes contact time Contact Checking Contact Condition Contact Time Probe Bounce Contact Checking Measuring The “Contact Improver” function improves bad contacts between probes and test samples. Contacts errors are reduced by penetrating oxidation and impurities between probes and samples. Reducing contact errors can increase productivity and quality. The intensity of the Contact Improver function can be adjusted to suit the probe type. Bad Good Detection Voltage Error Output ERROR Large detection voltage fluctuations indicate an error. Retry Function Re-Measures After Faults The Retry function automatically retries measurement when a fault occurs due to probe chatter. This can decrease the contact error rate and contribute to productivity improvement. Retry Function Probe Bounce Contact Improvement Contact Condition Contact Condition Contact Improver Function Good Contact Time Contact Improver Function Makes Reliable Contacts Quickly Contact Improver Function The Voltage Monitor function detects large voltage fluctuations due to changes in current terminal contact resistance or noise from mechanical vibrations as contact errors. This increases the reliability of the measured values. Voltage Monitor Function Measuring Contact Checking Before and After Measuring • Contact condition during Contact measurement is probe- Condition dependent. • Because measurement is not allowed during contact checking, speed is slow. Probe Bounce Voltage Monitor Function Monitors Contact Condition Changes ON ON Retry Contact Improver Function ON ON ON Contact Check Checking Contact Check Checking Checking Measurement Measuring Measurement Measuring Retrying Probe Short-Circuit Detection Function Ensures Reliable Four-Terminal Measurements A conductive foreign object between the POT and CUR probe tips inhibits reliable four-terminal measurements. Short-circuited probe anomalies are detected by checking the resistance between these tips when not measuring. Probe Short-Circuit Detection DUT Electrode Foreign Object CUR Settings Monitor Function Minimizes Risk of Human Error When using two instruments, a difference in settings disables TRIG input and causes warning notification. This function eliminates setting mistakes caused by human error. DUT (sample) POT Automatic Comparison 4 Ultra Fast and Accurate Resistance Measurement 3 .

This voltage affects measurements, and if large enough, can cause measurement errors. The offset voltage compensation function minimizes the effect of thermal EMF to maintain measurement accuracy. Particularly when measuring low resistances where the detection voltage is small, and during low-power resistance measurements, OVC is essential to maintain accuracy. Self-Calibration To maintain accuracy, self-calibration automatically corrects for offset voltage and gain drift of the internal circuitry, and minimizes the effect of changes in ambient temperature and other time-dependent variables. Self-calibration is performed every ten minutes starting when the instrument is turned on, and whenever measurement settings are changed. Triggers occurring during self-calibration are automatically delayed until calibration is finished. When measuring at the time self-calibration is to be performed, calibration is delayed until the measurement is finished. By syncing with the EOM signal, measurements can continue without disruption by the calibration process. Power Engineering Supports High Precision Measurements Strong immunity to noise and mains voltage fluctuations! Measurement values are unaffected even in the presence of ±1.5kV power line noise. The floating measurement circuit design is highly impervious to electrical noise, minimizing the effect on measured values even in noisy environments, such as near large switching inductors. The free-range AC input (90 to 264 V) is practically unaffected by voltage fluctuations, so stable measurements are possible even in poor power environments. Auto-Sensed Power Line Frequency Measuring in sync with the power line frequency is important for achieving accurate measurements. To avoid measurement problems from incorrect setting, the power line frequency is automatically sensed and selected (50 or 60 Hz). 50 Hz / 60 Hz 5 Meeting a Variety of Resistance Measurement Applications 4. Supports resistance measurements of chip inductors, EMC suppression components, and shunts. Low-Power Resistance Measurement Mode Included For ranges from 1000 mΩ to 1000 Ω, low-power resistance measurement is provided to minimize measurement current. Low-power resistance measurement provides accurate measurements using the thermal EMF compensation (OVC) function. Stable measurements are available even of components that are otherwise difficult to measure with high current, such as ferrite-bead and multilayer inductors*. * Inductors cannot be measured in the 1000 Ω to 100 MΩ ranges (Low-Power mode is disabled). Low Resistance Measurement Measure small resistances such as shunts and PTC thermistors. The 100 mΩ range provides 100 nΩ measurement resolution. 5 . Ideal for sample inspections during the manufacturing process High-Speed Data Output and Large Memory Measurement data can be transferred at 5 ms per value using the RS-232C interface and the data output (export) function. Values are sent automatically at the end of triggered measurements. Up to 30,000 values can be stored, and for quality control, all data can be downloaded at the end of measuring each reel. This function is ideal for system setup, debugging and process management. Auto-Memory Function In chip resistor manufacturing, the auto-memory function is convenient for sample inspections after screen printing. Measured values are automatically acquired and simultaneously subjected to statistical calculation as soon as they stabilize. When the specified number of measurements is acquired, a beep sounds and memory storage stops. Press PRINT to print measured values and statistical calculation results. (Printing requires the optional printer. The probe shown at the right is the optional, special-purpose Pin Type Lead 9771.) Statistical Calculation Functions To facilitate observation of process conditions, the mean (x), maximum (Max), minimum (Min), overall standard deviation (σ), standard deviation of sample (s), and process productivity indices (Cp: dispersion, CpK: bias) can be calculated using up to the maximum of 30,000 stored measurements.
