3.3 Hold Functions
3.3.2
Refresh Hold Function
The refresh hold function locks the display value auto-
matically once the measurement value stabilizes. As the
display value remains locked even if you remove the test
leads from the test subject, this function is useful when
you are measuring in locations where it is difficult to see
the display value or when you are using both hands to
take measurements.
1.
Set the refresh hold threshold value (the amount of
change once the display has stabilized).
❖
Setting method of threshold value:
See Section 4.7 Refresh Hold Setting (page 58)
2.
Press the
HOLD
key to set the instrument to wait for the
trigger.
3.
Connect the test lead to the test subject. Once the display
value stabilizes, "
HOLD
" lights, a buzzer sounds and the
display is locked.
4.
After confirming that the buzzer has sounded, remove the
test lead from the test subject.
The display value remains locked, "
HOLD
" flashes and
the instrument waits for the next trigger.
To cancel refresh hold mode, hold down the
HOLD
key.
