3541

3541 RESISTANCE HiTESTER Components measuring instruments Measure from very low (µ Ω) to very high (MΩ) resistances with a single instrument Along with capabilities for fast, precise measurements over a broad resistance range, Model 3541 also provides functions for temperature correction, comparator and data I/O. Employing a four-terminal measurement method, this instrument is particularly suitable for measuring the resistance of motor and transformer windings, relay/switch and connector contacts, PCB patterns, chip inductor DC resistance and in shipping inspection tests. 0.1 µΩ (20 mΩ range) to 110.000 MΩ http://www.hioki.co.jp/ HIOKI company overview, new products, environmental considerations and other information are available on our website. 1 Speed & Precision at Their Highest From the Laboratory to System Applications (All indicators shown lit for purposes of illustration) Major Features q Wide Measurement Range 0.1 µ Ω (20 mΩ range) to 110.000 MΩ q Measurement Fault Detection Enhanced measurement reliability by monitoring contact using all four leads q High Speed & High Precision Measurements As fast as 0.6 ms with 70 ppm precision (in the 2 kΩ to 110 kΩ range) q Temperature Conversion Function Uses resistance to shows temperature variations of measurement objects q Low-Power Measurement Function Essential for DCR measurements of chip inductors and connector contacts q Offset Voltage Compensation Minimizes thermoelectromotive effects q Comparator and BIN Functions Fast PASS/FAIL judgments, and measurement value ranking in ten levels q Equipped with EXT I/O, GP-IB and RS-232C interfaces Easily integrates into automated production lines q Two Types of Temperature Correction Correction by Pt sensor or infrared thermometer q Statistical Calculation Functions Use for process analysis and quality control q Multipolar Connector Low thermoelectromotive force supports high-speed measurements q Stores up to 30 sets of measurement conditions Measurement conditions can be changed quickly q Data Printing Print out measurement values and calculation results (with optional Model 9670 Printer) 2 s Comparator Compares measurements with preset upper and lower limits, and displays and outputs the judged range of each measurement. Two setting methods are available: absolute value (upper/lower limit setting) and relative value (% of a reference value), and judgment results, indicated by Hi, IN or Lo LEDs and beeper, are also output via EXT I/O, RS-232C and GPIB interfaces. x Judgments Hi: Display Value > Upper Limit, or OF IN: Display Value between Upper and Lower Limits Lo: Display Value is < Lower Limit, or -OF x Relative Value Judgment Display: {(Measured Resistance) – (Reference Value)} / (Reference Value) -99.999% to 99.999% x Beeper OFF: Beeper does not sound IN: Beeper sounds when the judgment result in IN Hi/Lo: Beeper sounds when the judgment result is high or low Upper Limit Setting Lower Limit Setting q Setup by Upper (Hi) and Lower (Lo) Limits Upper and Lower limit range: 0 to 999,999 Reference Value Setting % Setting q Setup by Reference Value (REF) and Range (%) Setting range: Reference Value = 0 to 999,999 % = 00.000 to 99.999% BIN No. (0 to 9) Enabled / Disabled s Classify measurements in up to ten ranking BINs According to a preset range, measurements can be classified in up to ten ranks (BIN0 through BIN9). Settings are the same as for the comparator, using either absolute or relative values with results displayed and output to EXT I/O, RS-232C and GP-IB interfaces. q Setting ranges are the same as for the comparator function. ] Absolute Value or Deviation Settings s Store up to 30 sets of measurement conditions Including settings for comparator and BIN measurements, up to 30 sets of measurement conditions can be stored and recalled by just selecting a setting number, so setting conditions can be changed quickly.

Even when the measured object is not at ambient temperature, temperature correction can be applied. Actual temperature can be measured as well. (When connecting the thermometer to the RS-232C interface, the GP-IB function is not available.) HIOKI 3444/3445 TEMPERATURE HiTESTER Modular cable s Settings For example, the resistance of a copper wire that measures 100Ω at 30ºC ambient can be corrected for display as the resistance it would have at 23ºC by applying the thermal coefficient (3930 ppm for copper when the conductivity ratio is 1), using the following settings. Reference Temperature Thermal Coefficient Reference Temperature Setting Range: –10 to 99.9ºC Thermal Coefficient: –9999 to 9999 ppm For proper correction, the measurement object must be at ambient temperature. Model 9451 Temperature Probe (supplied accessory) AC adapter Analog output Cable: 9305 Expansion box 3909 INTERFACE PACK (Expansion box & Modular cable) RS-232C Cable: 9637 s Convenient Temperature Conversion Function for Motor Coil Verification Initial Resistance Temperature increase (∆t) is obtained and displayed by converting resistance measurements and ambient temperature. This function is especially useful for verifying motor windings or coils, where the maximum temperature increase needs to be determined when current is applied. *The temperature conversion function cannot be used simultaneously with the temperature correction function. ➀ When a motor or coil has thermally stabilized at room temperature, measure the resistance (r0) and ambient temperature (t0) before applying current. ➁ Excite the coil, and when the temperature increase appears to saturate, remove the excitation. ➂ After removing excitation, determine the temperature (∆t1 to ∆tn) from the resistance (rt) measured at each specific time (t), and the ambient temperature. ➃ Project the curve through the collected temperature data (∆t1 to ∆tn) to estimate the maximum temperature increase (∆t). ∆t Initial Temperature Constant Temperature [ Temperature Conversion Setting Mode ] ➃ Initial Temperature ∆t1 ∆t2 ∆tn ➀ ➁ ON Excited OFF 1 2 3 ➂ n Time For measurements unaffected by test leads or contact resistance - Four-Terminal Resistance Measurements Constant current source Is Voltmeter r2 r3 r4 With two-terminal measurements, the conductor resistance of the test leads and the contact resistance of the connections are included in the measured resistance, resulting in measurement errors. The four-terminal measurement method employs a very high input impedance voltmeter, whereby almost all measurement current is conducted through measured resistance R. By measuring the voltage drop across only R, its resistance is measured without being significantly affected by r1 to r4. r1 E Resistances R (Values r1 through r4 are the combined resistances of the test leads and contact resistances.) R= E Is 4 Multi-functional support for various applications s Measurement Fault Detection Integrity of source and sensor leads and the constant-current supply are continually monitored to ensure measurements with high confidence. When a measurement fault is detected it is indicated on the instrument, and ERR is output from the EXT I/O interface. s Multipolar Connector A sealed shielded, low-thermoelectromotiveforce multipolar connector (INPUT B) is provided. The excellent noise immunity of this input makes it ideal for high-speed measurements of large resistances, as well as low power measurements. s Offset Voltage Compensation Thermoelectromotive force occurs at the contact point of different metals. This force affects measurements, and if large enough, it can result in measurement errors. The offset voltage compensation function minimizes the effect of thermoelectromotive force to preserve measurement accuracy. s Low Power Measurement Measures with 10 µ Ω resolution (2Ω range) using just 10 mA measurement current. This is ideal for measuring chip inductor DCR and connector contact resistance. (Low power measurement is available in the 2Ω to 2kΩ ranges) s Self-Calibration Consistent accuracy is maintained by automatic correction of internal circuit offset voltage and gain drift. Self-calibration is applied at every measurement using SLOW1/SLOW2 sampling, and every 30 minutes with FAST/MEDIUM sampling. Self-calibration is also performed at power on, and when measurement conditions are changed. (Self calibration is enabled when AUTO is selected) s Average Measurement values can be averaged to minimize display instability. With Free Run selected, the display shows the moving average; otherwise, the display shows the average value over a period. The number of samples to average can be set from 2 to 100. s Statistical Calculation Functions To observe process conditions, the mean (x), maximum (Max), minimum (Min) overall standard deviation (s), standard deviation of sample (s) and process productivity index (Cp: dispersion, CpK: bias) can be calculated using up to the maximum of 30,000 measurement values. s Data Printing Measurement values, and those including judgment results and statistical calculation results can be printed using the optional Model 9670 Printer.
