RM2612 Resistance Calculation Software
Operating modes Operating modes (initial value: potential measurement + analysis)
• Potential measurement + analysis
• Potential measurement
• Analysis
Explanation of operation
• Potential measurement + analysis: Instrument performs potential measurement and
then analysis.
• Potential measurement: Instrument saves measured potential data to a le (one le
per measurement).
• Analysis: Instrument loads a potential le saved during potential measurement,
analyzes the le, and saves the results to a le. Multiple les can be selected, and
analysis can be performed continuously.
Current error detection The instrument detects current errors, aborts measurement, and recommends that
the user change the range.
Display: “ERROR”
Resistance over-range
detection
The instrument detects over-range events and recommends that the user change
the range.
Display: “ERROR”
Contact check function Contact check ON/OFF
Resistance threshold: 1

[2.000E+04])
Input format: Decimal, exponential, up to 3 decimal places “0.000E+0”
• Display: “CONTACT ERROR”
• The instrument performs a simple measurement of the contact resistance between
the probes and the measurement target using two-terminal measurement and
concludes that a contact error has occurred if the resulting value is less than the
applicable threshold.
• Contact error probe identication (estimation) function
The instrument combines measurements of the resistance between probes using
two terminals and identies which probes triggered the contact error.
Measurement reliability
indicator function
Provides the following data for measured potential:
• Consistency (legitimacy of the relative magnitude of center 5 points): PASS/FAIL
• Variability per current channel: Current coefcient of variability [%]
• Percentage of data rejected by the error data rejection function (error rate): [%]
(Measurement is stopped in the event of a FAIL result for consistency.)
Error data rejection
function
Rejection function ON/OFF (initial value: OFF)
Rejection of error data
• Data with current errors is rejected.
• Current channel data with a consistency result of FAIL is rejected.
• Potential data from probes with contact errors is rejected from the calculation
process.
Counter function Functionality for counting the number of measurements performed since the
application was launched (can be reset by user)
Counter values are output to analysis results les and potential les for analysis to
serve as a rough guide to the number of measurements performed by the RM9004
Test Fixture.
Comment entry function Text entered into the comment eld is linked to the measurement target and output
to a le.
1 comment per measurement (up to 30 characters)
