2. Press the START/STOP button on the front panel so that the button’s LED
indicator lights.
3. Confirm that the digital multimeter display reads 0.1 V (the low level) or

higher.
6. Move the pin header cable connected to the P3410 CH0 output pin to the
CH1 pin and repeat steps 3 through 5. Confirm the output levels for CH2
through CH11 in the same manner.
This test confirms that accuracy of the delay relative to CH0 in the P3410 is
within the range
2 ns. This test is for the channels that support variable delay
times, i.e., channels CH8 to CH11.
