CAUTION
To avoid damage to the instrument, do not apply a voltage
between the positive (+) SOURCE and SENSE terminals
or between the negative (−) SOURCE and SENSE
terminals. Also, do not perform measurements when the
instrument has been turned o󰀨.
For the calibration environment, see the accuracy guarantee
conditions in “9.3 Accuracy Specications” (p. 123).
Calibrating the resistance measurement unit
• Use standard resistors that are subject to minimal levels
of deterioration with age and have stable temperature
characteristics.
• Use four-terminal-structure resistors to avoid e󰀨ects due to the
resistors’ leads.
• Always use the AC having a frequency of 1 kHz to calibrate the
resistances. A wire-wound resistor, which has a higher inductance
component, does not have e󰀨ective resistance (the real part
of impedance; the component displayed on the instrument)
equivalent to pure resistance (DC resistance).
• Connect the instrument and a standard resistor as shown below:
