• The instrument has an output resistance of 1 k. Connected devices must
have an input resistance of at least 10 M
. (The output voltage is divided by
the output resistance and input resistance, resulting in a reduction of 0.1% for
1 M
.)
• Connecting a cable may result in external noise. Implement a bandpass filter
or other measures as needed in the connected device.
• The analog output's GND pin is grounded (to the metallic part of the case).
• The output voltage is updated at the resistance measurement sampling tim-
ing.
• Recorded waveforms are stepped (since the output circuit response is
extremely fast compared to the update period).
• When using auto-ranging, the same resistance value may result in 1/10 (or 10
times) the output voltage due to range switching. It is recommend to set the
range manually.
• Output is set to 0 V when changing settings (range switching, etc.) and when
the instrument is turned off.
