Enabling smooth mode

Smooth is used to smoothen the refresh rate of the readings

in order to reduce the impact of unexpected noise and to

help you achieve a stable reading.

The smooth refresh rate can be set from 0001 to 9999. The

smooth time is defined as the set value +1. Smooth will be

restarted when the variation count is exceeded, when the

range is changed, or after a multimeter function or feature is

enabled. The variation count is set to the value used for the

AutoHold feature (see “Changing the variation count” on

page 113).

You can enable Smooth by holding while turning on

the multimeter (“Power- on options” on page 13). This

method, however, is temporary and Smooth will be turned

off when you cycle the multimeter’s power. You can

permanently enable Smooth from the setup menu.

To change the smooth refresh rate:

1 Press for more than 1 second to enter the

multimeter’s setup menu.

2 Browse to Menu 5 > SMOOTH, and press edit the

value.

3 Use the arrow keys to change the smooth refresh rate.

Select E to enable the Smooth feature.

4 Press to save your changes (or press to

discard your changes).

5 Press and hold until the multimeter restarts to return

to normal operation.
