*1 Voltage axis sensitivity of 1 mV/div can be achieved by digital zooming (2 mV/div x 2).
*2 Measured with the internal clock selected as the timebase and the voltage axis sensitivity set to “CAL”, after calibration following a 30-
minute warm-up, under the standard operating conditions stipulated on page 16-8.
*3 Measured with the input short-circuited, record length set to 10 KW, acquisition mode set to normal mode and accumulation function OFF.
*4 Record length displayed on the screen
*5 Typical values are described in terms of typical of average performance. However, they cannot be guaranteed.
