Testing Ohms Output

Use the precision DMM to measure the resistance output. Figure 6-6 shows the
four-wire connections. Set the DMM to the "TRU OHMS" setting. See the 1281
Operators Manual for information on using the "TRU OHM" setting.
The Wavetek 1281 must be in the "loI" (low current mode) when
measuring 5 ohms in the 4 K ohm range or an overload will occur.
