The way to hold range is to make instrument automatically measure, and hold range after
measuring out correct and stable value, or select range according to the impedance of the
device under test, referring to the next table.

4.2.8 Open correction
Press SHIFT + OPEN to enter open correction menu.
AD2817C
’s open correction function can eliminate the effect of test cable,
test fixture and
stray admittance in parallel with the device under test, such as stray capacitance.
Perform the following steps to perform open correction:
1. Press
SHIFT
key at test status, and “
SHIFT
” at left corner is on.
2. Press
OPEN
key to select correction function, as Figure 4-2 shows on LCD.
