3. Shift Key
Measurement state : Shift Key is used to call the mode setting.
(It's on for more than 2 sec with Mode Key.)
: Shift Key is used to call the mode protect function，
or used to change it.
(It's on for more than 2 sec. → The current mode protect function
state is indicated. → It's on for more than 8 sec just as it is.
→ Change.《L-oFF ⇔ L-on》)
Setting state : Shift Key moves the flash figure when each setting, to the right.
: The output bit values decreases at the time of analog output
adjustment mode setting.
4. Display Key
Turning on ：When a power supply is supplied keeping pushing
an analog output adjustment mode setting.
(A stop of the analog output adjustment mode setting is power supply off.)
Measurement state : Display Key is used to call the offset value setting.
(It's on for more than 2 sec with Mode Key.)
: Display Key is used to switch the ratemeter/totalizer.
(Need to set "Mode No.6".)
Setting state : Display Key changes the flash figure when each setting.
: The output bit values increases at the time of analog
output adjustment mode setting.
5. Reset Key
Turning on ：Throw power supply while Reset Key pressed to call
initialization setting.
Measurement state：Resets the totalizer if offset value is set, change the
reading to an offset value.
It also resets the presetting output.
(When using EXT input (terminals No.6 - 7), need to set "Mode No.6".)
Setting state : Reset Key is used to register and make it measurement status.
: The bit value of "An-1 and 2" is registered at the time of
analog output adjustment mode setting.
6,7. Preset output LED (Orange)
Measurement state : "OUT1,2" turns on during generating preset output.
: "OUT1" LED turns on during generating a
synchronization pulse.
Setting state : The presetting output LED lights up at the time of the
preset output value setting.
8. Totalizer LED ( or "×10 LED") (Green)
Measurement state : It lights up at totalizer.
: When totalizer is being "x 10", it'll change to a flash.
(Need to set "Mode No.8".)
Setting state : It lights up at totalizer.

Throw power supply in with Reset Key pressed to initialize the settings.
After the initialization, the set values will be as shown in "Table.9-1",
"Table.9-２" and "Table.9-3".
Counter data and the mode protect function are also cleared.
！ < Caution >
* Since an initialization changes all existing setting values to the initial
setting values, be sure to record all the setting values before an
initialization.
* In case the computer froze when unusual functioning occurred with
the normal operation, initialize according to the above procedure and
set the desired value again.
