ASM-SENSOR 3541

3541 RESISTANCE HiTESTER
Components measuring instruments
0.1 µΩ (20 mΩ range) to 110.000 MΩ
Measure from very low (µΩ) 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.

Two types of temperature correction
■ Temperature correction functions regardless
of materials and temperature
■ Temperature Correction by Analog Output
(Infrared Thermometer)
Using the 9451 Temperature Probe, resistance values
measured at ambient temperature can be corrected by
applying a thermal coefficient so that the display shows the
corresponding resistance values at any other temperature.
Make temperature corrections by measuring the surface temperature of
the measurement object using the analog output from an infrared
thermometer, or through the RS-232C interface. Even when the
measured object is not at ambient temperature, temperature correction
can be applied. Actual temperature can be measured as well.
■ Settings
(When connecting the thermometer to the RS-232C
interface, the GP-IB function is not available.)
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.

■ 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.
Initial Temperature

Constant
*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.
➃

➁ Excite the coil, and when the temperature increase appears to saturate, remove the
excitation.
[ Temperature Conversion Setting Mode ]
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).

Resistances R
(Values r1 through r4 are the combined resistances of the
test leads and contact resistances.)
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.

Multi-functional
support for various
applications
■ Measurement Fault Detection
■ Multipolar Connector
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.
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.
■ 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.
■ Low Power Measurement
Measures with 10 µΩ 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)
■ Self-Calibration
■ Average
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.
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.
(Self calibration is enabled when AUTO is selected)
■ 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.
■ Data Printing
Measurement values, and those including judgment results and
statistical calculation results can be printed using the optional
Model 9670 Printer.
