An alternative method for measuring the output of the Current Loop converter is to
connect a 250 ohm ±1% resistor across the current loop output in lieu of the current
meter (see Figure 3-9 for pin assignments and diagram of the analog output connector).
This allows the use of a voltmeter connected across the resistor to measure converter
output as VDC or mVDC.
