11. Comparator (COMP Key)
This function is available on Model 51021.
The comparator function determines whether the measured value
(displayed value) is within the specified range, greater than the
high limit, or less than the low limit.
Set the low limit (Lo) and high limit (Hi) to define the reference
range. The maximum number of digits available is 8.
Of these digits, 3 digits are significant, and the rest are place
holders (fixed at 0; including 2 decimal digits).
The meter displays the comparison result.
