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.

Measurement values, and those including judgment results and

statistical calculation results can be printed using the optional

Model 9670 Printer.

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 Measurement Fault Detection

A sealed shielded, low-thermoelectromotive-

force 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 Multipolar Connector

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 Offset Voltage Compensation

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 2

Ω to 2kΩ ranges)

s Low Power Measurement

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 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.

(Self calibration is enabled when AUTO is selected)
