Operation Mode

Output mode Operation Example when input mode is either addition or Subject:ubtraction
Output maintain/
hold count
[HOLD-A]
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 completion.
Output maintain/
over count
[HOLD-B]
Output control is maintained after count-up completion and until resetting. However, counting is possible despite completion of count-up.
One shot/
over count
[SHOT-A]
Output control is maintained after count-up completion for a fixed time (approx. 1 sec.). Counting is possible despite completion of count-up.
One shot/
recount I
[SHOT-B]
Output control is maintained after count-up completion for a fixed time (approx. 1 sec.). Counting is possible despite completion of count-up. However, reset occurs simultaneous with completion of count-up. While output is being maintained, restarting of the count is not possible.

Notes:
1.Make the switch setting before installing to panel.
2.Please turn the power off if you change the setting of the count speed switch when the power is on. The setting will become valid when the power is turned back on

 

1.Front reset key
This key resets the count value. It does not work when the lock switch is ON.

2.Mode key
Use to switch between each mode.

3.Setting key
Used to set digits of preset values or set each mode.

4.Set key
Use to set preset values or to switch between modes.

5.Lock switch
Disable the operation of the front panel reset key and the mode key. With the lock switch on, is displayed for about two seconds when the reset key or mode switch is operated.

6.Count speed switch
Use this switch to switch the count speed between 30 Hz and 5 kHz.
