Refresh Hold
The hold function allows the user to hold the displayed
digital value. The bar- graph is not held, fix proportional to
real measurement value. Use the setup mode to activate the
Refresh Hold when working on a difficult measuring field.
This function will auto trigger or update the Hold value
with a new measuring value, and sound a tone to remind
the user.
Press to enter the Refresh Hold mode. The present
value holds, and the sign lights up. It is ready to hold
a new measuring value once the variation of measuring
value exceeds the setting of variation count, and the sign
flashes. The hold value is updated until the measuring
value is stable. Then stops flashing, lights up and
sounds a tone to alert the user. Press again to disable
this function.
