Key Protect Level
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the
key protect level (KP-1 to KP-7). The key protect level is set in the function setting mode. The key protect indicator is lit when the key-protect switch
is ON.
* Changing mode to DIP switch monitor mode or function setting mode.
Self-diagnostic Function
The following displays will appear if an error occurs.
*1. This includes times when the life of the EEPROM has expired.
*2. Occurs when the measurement value reaches 999,999.
*3. Display flashes (1-second cycles).
*4. The normal display and
e3
will appear alternately.
When the Hold Key is pressed,
e3
will not be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the counter will continue
without clearing the output ON count.)
