Figure 6-13. Typical Output Waveforms for Track/Hold Circuit (TP103)
To test whether the Ohms Current Source is actually being sourced out the HI and LO
OUTPUT terminals, select the 20 kΩ range and the 2-wire ohms function, connect a 10
kΩ resistor across the HI and LO INPUT terminals, and measure the voltage across this
resistor with another voltmeter. There should be a 1V drop across the resistor.
