Changing The Set Value; Cautions For Use - Panasonic LC4H-S Series Manual

LC4H-S
E The decimal point is set using the [UP] and [DOWN] keys to specify the 2nd, 3rd, and 4th digits (this applies only to 4-digit
models).(The 1st digit is set using the [UP] key or [DOWN] key in settings where there is no decimal point (this applies
only to 4-digit models).)
R Press the [RESET] key to set the displayed decimal point position and return to normal operation.
• Setting the pre-scaling value
Q Holding down the [SET/LOCK] key, press the key for the first digit to access the pre-scaling value setting mode.
Example) 4-digit type
W When the setting mode has been accessed, release the [SET/LOCK] key.
E Use the [UP] or [DOWN] key to set the pre-scaling value (this applies only to 4-digit models).
Select either: 0.001 to 9.999 (4-digit) or 0.001 to 99.999 (6-digit)
R Press the [RESET] key to set the displayed pre-scaling value and return to normal operation.
• Setting the one-shot output time
Q Holding down the [SET/LOCK] key, press the key for the third digit to access the one-shot output time setting mode.
W When the setting mode has been accessed, release the [SET/LOCK] key.
E Each time the 1st-digit [UP] key is pressed, the one-shot output time changes in the following sequence, moving to the
right:
→ 1 s → 0.5 s → 0.2 s → 0.1 s → 0.05 s → 0.01 s
(With a 4-digit type, the [DOWN] key can also be used to move to the left.)
R Press the [RESET] key to set the displayed one-shot output time and return to normal operation.

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) Suppose that thew counter is preset to
count down. Whether a preset count-
down value is smaller or larger than the
count value, the counter counts down to
"0 (zero)".
2. If the set value is changed to "0,"
the unit will not complete count-up. It
starts counting up when the counting
value comes to "0 (zero)" again.
1) Up-count (addition) input
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) Down-count (subtraction) input
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
The counting value does not become "0
(zero)" and so the counter does not
count up.
3) Directive, independent, and phase
inputs
The counting value is counted up or
down to any number other than "0" once.
When it comes to "0 (zero)" again, the
counter starts counting up.
