The relationship between the display value shown by the unit and the output
voltage is indicated below.
Ideal characteristics of the display value and the output voltage
Important
Using this feature will reduce battery life by
about 25 percent.
Delay
The unit incorporates an A/D converter which converts the sensor input
signal into digital format for processing by a DSP chip. The result is then
returned to analog format by a D/A converter and output as an AC signal.
Due to this process, the output signal has a constant delay time with regard
to the sensor input signal. The delay time is about 0.55 ms in waveform
recording, and about 1.1 ms in AC OUTPUT.
