When High is selected, the output level is normally low and the duration of the
selected pulse width is high When Low is selected, the output level is normally
high and the duration of the selected pulse width is low
Programming the K-Factor Scaler
OTE:
N
All information in the Program Values column must be entered before the
software can download the information to the K-factor scaler
Press Program to download the K-factor, pulse width and pulse output values
to the K-factor scaler At the completion of the programming cycle, the circuit
performs automatic verification of the downloaded information The K-factor
scaler retains downloaded values in the memory if it is disconnected from power
Press Read to load the current information from the K-factor scaler and display it in
the Board Values column
Verify performs the same function as Read, but compares the Board Values to the
Program Values and displays an error if the two do not match
Setting the Output to Use the Internal or External Pullup Resistor
Either the internal pullup resistor or an external resistor must be used for the
K-factor scaler to provide an output pulse This option is controlled by the onboard
jumper and not by the software
With the jumper installed, the internal 3 6 kΩ pullup resistor is connected to the
input voltage of the board With the jumper removed, the internal pullup resistor
is disconnected and an external pullup resistor and supply voltage are required
