• Changing the set value
1. It is possible to change the set
value with the up and down keys (4-
digit type only) even during counting.
However, be aware of the following
points.
1) If the set value is changed to less than
the count value with counting set to the
addition direction, counting will continue
until it reaches full scale (9999 with the
4-digit type and 999999 with the 6-digit
type), returns to zero, and then reaches
the new set value. If the set value is
changed to a value above the count
value, counting will continue until the
count value reaches the new set value.
2) If counting is set to the subtraction
direction, counting will continue until full
scale (-999 with the 4-digit type and -
99999 with the 6-digit type) regardless of
the new set value, and then the display
will change to with the 4-digit
type and with the 6-digit type.
2. If the set value is changed to “0,”
the unit will not complete count-up.
However, be aware of the following
points.
1) When counting is set to the addition
direction, counting will continue until full
scale is reached (9999 with the 4-digit
type and 999999 with the 6-digit type),
return to zero, and then complete count-
up.
2) When counting is set to the
subtraction direction, counting will
continue until full scale is reached (-999
with the 4-digit type and -99999 with the
6-digit type), and then the display will
change to with the 4-digit type
and with the 6-digit type.
