Note:
⚫
The output impedance is 100
Ω
. Please use a connecting instrument with an
input impedance of 5M
Ω
or higher.
⚫
If cables are connected, external noise may be picked up. Please use bandpass
filters, etc. on the connected instruments as needed. Connect the GND
terminal of the analog output to the ground wire (metal part of the casing).
⚫
The output voltage is updated based on the sampling timing of resistance
measurement.
⚫
The recorded waveform is in a stepped shape. (Because the response of the
output circuit is very fast compared to the update cycle)
⚫
In automatic range, due to range switching, even if the resistance value is the
same, the output voltage is 1/10 (or 10 times). It is recommended to use in
manual range.
⚫
When changing settings (range switching, etc.) and when the power is turned
off, the output is set to 0 V.
