Part names
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.
❇: Default setting when shipped.
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.
