Test 4-4: Resistance Test (4-Wire Ohms)

This test verifies the 4-wire resistance accuracy of the 2kΩ, 131kΩ, and

1MΩ ranges.

NOTE

The DC Voltage performance test must be performed prior to the

Resistance Test to check the A/D accuracy on all ranges. If the DC

Voltage test has not been performed, resistance must be checked on all

ranges at 0 and at 50% of full scale.

Equipment Setup 1. Connect the equipment as shown in Figure 4-4. You can connect

to the E1326B OR to the E1326-80005, but not to both.

2. Set the Agilent E1326B multimeter as follows:

•

Reset Multimeter ....................................................*RST

• Auto Zero ..................................................................ON

• Power Line Cycles (PLC) .............................................1

• Line Freq Reference (CAL:LFR) .......... 50 Hz or 60 Hz

NOTE

*RST sets Auto Zero to ON and Power Line Cycles to 1.
