2. Set the E1411 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.
Test Procedure 1.
Set the Resistance Standard to 1 kΩ setting
2.
Set the E1411 range to 1861Ω (2048Ω with 10% overrange)
with CONF:FRES 1861
3. Measure the input resistance with READ? and verify the results
are within specified limits (at the range selected for 1 PLC). Record
the results on the Performance Test Record.
NOTE
For best measurement accuracy, you may want to measure the ACTUAL
Resistance Standard value. You can do this by recording the front panel
display of the resistance value, or measuring the resistance with an 3458A
multimeter or equivalent.
For example, suppose the ACTUAL resistance value for the 1 kΩ setting is
1001.3Ω. Then, the Lower Limit for this value = 1001.03 Ω and the Upper
Limit = 1001.57Ω. These limits would replace the existing limits of
999.730Ω and 1000.270Ω shown in Table 4-1. If the measured value falls
within the revised limits, the test passes.
4. Repeat steps 1 through 3 using the following Resistance Standard
settings:
E1411 Range 10%
overrange

5. Remove power and disconnect test equipment.
