Check Before Calibrating the Resistance Generation Function
Generate the one of the appropriate resistance values listed in the following table from
the instrument, and measure the output voltage using a DMM. If the measured value
deviates from the tolerance, calibration is unavailable when generating resistance.
Contact your nearest representative.

CAUTION
• Do not apply a voltage exceeding the maximum input voltage;
otherwise, the input part may be damaged.
• Do not short-circuit or apply an external voltage to output
terminals of the instrument or standard equipment, or else their
internal circuitry may be damaged.
