2.10.7 Power ON Output Value Setting
Wire the units in the same manner as in the “Pulse Interval Accuracy Test,” enter all
settings (PWM output settings), then confirm that the criteria are met.
The wiring diagram for the pulse interval accuracy test shows an example of wiring CH5.
Actual measurment should be performed on all channels.
Use an external power supply of 5 V, and load resistance of 100 Ω.
PWM Outupt Settings
<MX100 Settings>
Connect to the PC, then enter the following settings using the MX100 standard software.
When using the MX100/DARWIN API for settings, enter settings that are equivalent to
the following.

Criteria (for the MX100 and MW100)
Power cycle the MX100 main unit or equivalent, then measure the output values without
entering any settings using the PC.
Use a trigger level of 2.5 V. In this case, confirm that the output voltages of all channels
are within the allowable ranges.
