Question number FAQ-0937
In the TM-3100, when the input amplifier configuration is set to PULL UP, what is the voltage of the power supply and what is the resistance value used for the PULL UP?
The power supply is 12V, and the resistance value is 1kΩ. It is pulled up via an analog switch. The external device will not operate unless its low level is below 1V.
