Refresh Hold
The Refresh Hold function allows you to freeze the displayed value. The bar-graph
is not held and will continue to reflect the instantaneous measured value. You can
use the Setup mode to enable Refresh Hold mode when you are working with
fluctuating values. This function will auto trigger or update the held value with a
new measured value and emit a tone as a reminder.
1 Press to enter Refresh Hold mode. The present value will be held and
the symbol will appear.
2 It will be ready to hold a new measured value once the variation of measured
values exceeds the variation count setting. While the multimeter is waiting for
a new stable value, the character “R” in the annunciator will flash.
3 The annunciator will stop flashing once the new measured value is
stable and the new value will be updated to the display. The
annunciator will remain on and the multimeter will emit a tone to remind you
of this.
4 Press again to disable this function. You may also press for more
than 1 second to quit the Refresh Hold function.
