Refresh Hold
The hold function allows the user to hold the displayed dig-
ital 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.
