* If a DC voltage generator meeting the standards above is not available, you can ensure that
the stated voltage is output by substituting a FLUKE 9100 or equivalent and monitoring the
output voltage using a DMM. Also, due to the output impedance, some voltage generators
cannot output all stated voltages, and at 0 V, there are many cases where the above
standard is not met, so 0 V can be obtained by shorting the terminals. It is recommended to
monitor when set to DOWN.
† Measure the setting value and actual output value, then confirm that the above standards
are met.
0.2 Ω or less cannot be set on the ADR-1202, so 0 Ω can be achieved by shorting the
terminals.
‡ Ensure that the module settings and measured values can be read in.
