Coupled with the proper jumper selection, a "-OPEN" indicates the input is
below the bottom limit of the range selected.
This display occurs when the input scale and/or offset applied to the input
signal causes the display to go into a numerical overflow.
This display occurs when the reading scale and/or offset applied to the input
signal causes the display to go into a numerical overflow.
When a display value near the maximum display capability is forced into a
numerical overflow by changing the CNT BY menu (for example, the display
reads 999997 and the count by is changed from 001 to 005 and rounds the
display up to 1000000).
If a unit of measure is selected and you are near the full scale capability of
the display and in the ACTIVE decimal mode, the display will shift one digit
to the left (for example, to a display of 1065.33 you add a unit of measure
such as "F" for a display of 1065.33F), the display will flash "UOM.OVF".

numerical overload.
Press the 'MAX' button to reset the entire display to all
zeros, then enter a revised number into the submenu
item that caused the overflow.
DEC PT (decimal point) position has been moved one
or more places to the left driving the programmed
offset value into numerical overflow.
Press the 'MENU' button and the meter will show the
left most decimal point position possible for the chosen
offset: by pressing the 'MENU' button again this
revised entry is stored.
Alternately, the amount of RDG.OF may be reduced to
get the decimal point further to the left.
