Resistance measurements for all ranges are made using a two-wire
ratiometric technique. This means that test lead resistance may affect the
accuracy in the 200 range. You can correct this error by shorting the test
leads together, reading the test lead resistance, and then subtracting it from
resistance readings. The most convenient way to do this is with the relative
function as described later in this chapter. This technique is also useful for
removing the .02 error factor in the 200 range (refer to resistance
specifications in Chapter 1).
2-18. Autoranging Megohms
When the autoranging M range is selected, the 8062A automatically selects
the range appropriate for the measurement. The measurement resolution
decreases in the two higher M ranges as shown in Table 2-3. Readings
made at the crossover points between ranges are microcomputer-stabilized
by an offset in the upscale and downscale directions. Range changes are
made at 2.00 M and 20.00 M as readings go upscale, or at 19.0 M and
1.90 M as readings go downscale.
