2.5 Insulation Resistance Measurement
2.5.3 Switching the Number of Display Digits
The IR4052 provides functionality for switching the number of
display digits.
Insulation resistance values for insulated objects are unstable by
their nature. Consequently, the lower digits of displayed values
may occasionally oscillate back and forth. In such a situation,
work efficiency can be improved by reducing the number of
display digits.
Switching the number of display digits
Press
to switch the number of display digits. Each time you
press
, the number of display digits will change as shown in
the following table. You can see what number of digits is
currently being displayed by looking at
on the bottom
of the display. When the number of display digits is in 100 count
or 10 count mode,
lower digits that are not displayed are
discarded
. For example, a reading of 57.9 M
:
in 1,000 count
display mode would be shown as 57 M
:
in 100 count mode or
50 M
:
in 10 count mode.
