4. OUTPUT VOLTAGE PROGRAMMING BY EXTERNAL RESISTOR
Fig 4-5 shows a typical set-up for programming the output voltage. A variable programming resistor,
0~4Kohm produces a proportional output voltage from zero to full scale. In order to set the low limit, a
series resistor can be connected to the programming resistor. For example; a 1kohm series resistor will
set the lower limit to 25% of full scale. In order to set the upper limit, a resistor can be connected in
parallel to the programming resistor. The resultant programming resistance of the series/parallel
resistors must be between 0 and 4Kohm.
Resistive programming is possible for local and remote sensing.

Constant voltage resistive programming.
5.OUTPUT CURRENT PROGRAMMING BY EXTERNAL RESISTOR
Fig 4-6 shows the set-up for constant current resistive programming. The explanation given for
constant voltage resistive programming also applies for constant current.
