This function can be used if
a no-input state will continue
for approximately 1 minute
when the unit is turned on.
Check the unit if there is
any input as the following
may occur:
•
The screen display may
indicate FAIL.
•
Zero-adjustment data may
be cleared.
•
A large error component
may result.

When this function is
disabled, press the

Use this to save the current
settings (except the auto
power-save function setting,
which will not be saved).
•
You can then measure
using the saved settings
right away when you next
power up.
The unit will detect the
sensor type, including
whether it is an AC sensor
or an AC/DC sensor, its
rating, and its output rate.
Settings can be saved
for each sensor type. So,
for example, CT7636 and
CT7736 will be identified as
the same sensor.
•
Settings saved may be
deleted as a result of
calibration or repair. Check
the setting status before
using the unit.
