2. Output mode

For the output mode, you can choose one of the following seven modes

• Maintain output/hold count

• Maintain output/over count 

I

• Maintain output/over count 

II

• One shot/over count

• One shot/recount 

I

• One shot/recount 

II

• One shot/hold count

Operation

(Example when input mode is either addition or subtraction)

Output control is maintained after
count-up completion and until resetting.
During that time, the count display does
not change from that at count-up com-
pletion.

* n: Set value

Maintain output

Over count 

I

HOLD-B

Output control is maintained after
count-up completion and until resetting.
However, counting is possible despite
completion of count-up.

* n: Set value

Maintain output

Over count 

II

HOLD-C

Output control is maintained after
count-up completion and until the next
signal enters. However, counting is
possible despite completion of count-
up.

* n: Set value

One shot

Over count

SHOT-A

Output control is maintained after
count-up completion for one shot output
time. Counting is possible despite com-
pletion of count-up.

* n: Set value

One shot

Recount 

I

SHOT-B

Output control is maintained after
count-up completion for one shot output
time. Counting is possible despite com-
pletion of count-up. However, reset
occurs simultaneous with completion of
count-up. While output is being main-
tained, restarting of the count is not
possible

* n: Set value

One shot

Recount 

II

SHOT-C

Output control is maintained after
count-up completion for one shot output
time. Counting is possible despite com-
pletion of count-up. However, reset
occurs simultaneous with output OFF.

* n: Set value

One shot

Hold count

SHOT-D

Output control is maintained after
count-up completion for one shot output
time. During that time, the count display
does not change from that at count-up
completion. Reset occurs simultaneous
with output OFF.
